RN30 Reduction, similarity to Lavieri's Reducer in Altair etc. 9.82473769 x 10^22 CVs (approx. 98 sextillion). (a) no effect (b) Pawns 'reduce', so that any piece adjacent to enemy Pawn can move/capture one square only. 'Reduced' B, R, Q go one square only along their regular paths, whereas Knight thus reduced becomes Wazir + Ferz and Falcon becomes Squirrel(N+Dabbabah+Alfil) all leaping components with no two-path necessary. (c) 30b Pawn reduction does not extend to Falcons. (d) 30b Pawn's reducing ability covers only Knights and Falcons. (e) 30b Pawns reduce only if on dark-square half of board. (f) 30b Pawns reduce (all enemy others adjacent) only once having crossed the center line. (g) 30b Pawns reduce only by lateral or forward one-square adjacencies. (h) 30b Pawns reducing (not isolated) next to last rank, one step from promotion, are themselves immune to capture at all. In tribute to the size range we pass through currently>  Elephants and Sunflowers: long stems;  Camels and Peanuts: humps.

RN31 Acid-Base: Pairwise same-type adjacent opposite-side pieces mutually lose their capturing ability. (a) no effect (b) Opposite-number Knights adjacent, diagonal or orthogonal, have their capture ability 'neutralized', negated. They can only move away without capturing. (c) Opposite Falcons so adjacent cannot capture, called the Acid-Base effect. (d) Acid-Base applies to Knight and Falcon. (e) A-B extends to all paired same-type opposite-side pieces adjacent. (f) Any opposite-side piece (not pawn) adjacency neutralizes each other's capture capability, irrespective of piece-type. (g) 31f applies only to pieces wholly in the two central files (e&f), the Cauldron. (h) 31f applies centrally to opposite pairs(any mix of types) within files d,e,f,g, the Wide Cauldron. 7.859790152 x 10^23, approx. 786 sextillion, exceeds Avogadro's number.

Chieftain Chess. Missing description (16x12, Cells: 192) [All Comments] [Add Comment or Rating]

Thanks, Joe, why not bracket[] changes after the first week of an article? Original date '2006-07-30' retained still so far is misleading. For research or priority, the practice, to the extent widespread, makes write-ups nearly worthless (even if not actually changing Rules or games, as sometimes done). JJoyce's correction helpful enough, also sets off against not respecting even Edgar Rice Burroughs' 100-year-old two-square- and three-square-moving pieces, ever to include them or similar priorities, and yet his making issue of 'provenance' etc. What a burden left for anyone to sort out even when something is written let alone invented! By contrast, in stretched analogy, one misspoken word at, for example, USA Presidential debate, within their narrow doctrinal framework, can eliminate candidate.

Rhino. A set of pieces which combine the movements of the Mao with that of the Wazir.[All Comments] [Add Comment or Rating]
George Duke wrote on Tue, Nov 20, 2007 08:47 PM UTC:Excellent ★★★★★
At Aronson's Rhino piece description, Joe Joyce enunciates the doctrine of re-inventing the wheel in immediately preceeding Comment. ''I actually think it can be good that people re-invent the basics. How's that for putting a good spin on re-inventing the wheel?'' As for piece values, Aronson points out Rhino can reach twice the squares as Nightrider, but the latter is more valuable in our estimation. Ralph Betza is credited with inventing Rhino, Mirror Rhino, and Double Rhino. Obfuscation mentions Aronson and Friedlander as independently 'inventing' one or more of them, but we do not buy that. Betza invented them, unless someone comes up with examples or documentation of other earlier uses. That is because invention credit is determined, generally in all fields, by assumption that someone 'skilled in the art' is more or less omniscient of relevant prior uses, or should so be aware of them, or subject to them if unaware. Occasional actual simultaneity, or overlap in time before publication, is another matter (maybe like Newton and Leibnitz in Calculus). So many efforts are also why it becomes harder to invent chess variations and pieces for the time being. There is simply more to be studied first, although recent prolificists apparently choose to study less pre-existing CVs. Hence for now not so good quality as before. Double Rhino is multi-path, namely two-path beyond its first square. Charles Gilman's Comment April 2004 here adds at least four more pieces after these hippogonally-directed move directions.

Illusionary Piece Chess. A piece and a Pawn on each side are more powerful, but can not offer check or prevent bare King. (8x8, Cells: 64) [All Comments] [Add Comment or Rating]
George Duke wrote on Wed, Nov 21, 2007 12:24 AM UTC:Good ★★★★
Here player upgrades one piece and one Pawn by own choice and then all the play is normal except for following sentence. The two-per-side substitutes situated in standard array can never check. Interesting are the upgrade possibilities. Knight becomes Squirrel. As Betza's Chess Different Armies forces are set up by Betza for rough equivalence, here in Illusionary player needs sense of which enhancement is best for own skill, in choosing the piece to expand. Pawn becomes (Pawn + Berolina), close but not identical to Sergeant of 1940's Wolf Chess. Neither radical nor pretentious change for OrthoChess fans, like the teacher's Comment suggests.

Objectors should be disabused of any notion that fully 33 Mutators are impractical and cannot be employed serially. The following notation, being perfectly playable with perhaps ready crib sheet, has all Mutators, or descriptors, activated (no Mutator at all registering default 'a' mode), and admittedly defines the most complex yet still illustrative type of prospective CV -- showing that such extremity as this(that one would not ordinarily want to play) nonetheless legimately counts in the mounting tabulation. To wit, '1c2b3c4b5b6c7d8b9b10e11c12c13b14b15b16b17b18b19b20c21d22b23b24d25b26d27b28b29e30f31b32c' represents Falcon Chess 10x10 array FRNBQKBNRF, each piece-type enhanced or limited in turn: Chaturanga (one-step) Pawns able to move two pawns at a time for any turn optionally(RN10) and promoting to Queen too, and said Pawn 'reducing' opponents (to one step) adjacently after having crossed center line(RN30); Rook and Queen both only able to go up to 4 squares, and Queen alone able to 'teleport' any adjacent piece(RN23), and opposite Queens only that attack each other thereby immobilizing Kings(RN32); Knight having Camel leap able to 'stone' adjacent piece(lasting 10 moves, RN24) and also to capture inversely(RN25), and also exclusively immobilizing along own line of attack, and further when captured changing sides for later drop, and finally also adjacent opposite-side Knights negating each other's capture ability (RN31); Bishop (plus Wazir) able to rank-jump (RN19) alternatively and also able to swap places along line of attack [there would be priority of first actual mover creating a condition for any conflicting effects from ''overlapping'' 'adjacencies' and 'lines of atack'] and said Bishop having 'hegemony drop' ability(RN29) upon reaching last rank; Falcon (as Ferz too) able to move cylindrically(RN15) and capture coordinately(RN28); and King having Knight leap once per game. Pre-placed sequentially before Move One in front of Pawns are: both Knight-moving Immobilizer(RN11) and Promoter(RN12); two one-step Warp Points(RN14); and two Philosophers(RN27). Also permitted are triangular transference(RN13) and switching any adjacent pieces(prohibited when already 'reduced' by that adjacent enemy Pawn), both these factors in lieu of a regular piece or Pawn move(s).

As a practical matter, we shall not exceed 32 Mutators operational at a time(example 24.Nov.07). Hence the standard is 'X Mutators taken 32 at a time'. Goal of course is attaining one-to-one #CVs to #Atoms(in universe). For convenience, new Mutators after RN1-RN32 are 200-series, designated 201, 202... The 'Cumulative totals' go on as before because of the following. Doug Chathan 18.Nov.07 links J.P.Neto's year 2000 article 'Mutators'. By principles and notations there, we can expand RN1-32 themselves in tandem with restricting new Mutators at most 32 activated. Examples available are such as Neto's Inverse, if any, of a Mutator and applying a Mutator repeatedly until fixed point etc. These will be spelled out when used. Mostly, we shall add to the number of modes periodically beyond the customary eight(8) so far, 'a' through 'h', of already-established RNs 1-32(RN 7 for Pawns has ten 'a' to 'j') themselves. Deliberately, the two currents can keep the running 'Cumulative' closely equivalent to our technique(usually having been just to multiply by 8 each step of the way). In other words, reductions from requiring only up to 32 active are offset at will by additional modalities of pre-existing Mutators. Thus, the very same over-all method essentially holds and continues, viz., more and more good Mutators serially onto the same Basis -- thereby making more and more games. Occasional adjustment and re-calculation in keeping with that standard 'nCr', namely nC32, 'X Mutators 32 at a time', will be tolerated; and anyway, in the end, we should be able far to exceed 10^80, in workable and well-defined CVs, to compensate for any slight inaccuracies; which may also arise from occasional contradictions not easy to reconcile(among some unusual RNs, in combination, by their very wordings and effects). So, next one is 'RN200' rather than RN33.

Or are all the hexagonal variants ''funny-looking'' pentagonal ones? Ralph Betza's Rectahex Chess (2003) concludes ''Hexagonal Chess can be played quite simply on normal rectangular board.'' Betza's resolving hex dynamics there worsens visualization, but Rectahex is excellent for Betza's satiric, clever transformation. This Penturanga marginally improves ease of visualizing interpretatively-hex movements, in acceptable technique for claiming novelty at sophisticated stage as this, pursuant thousands of forms. Differently -- hey, there are hundreds hexagonal chesses, so why not a hundred pentagonal ones -- US Patent No. 4357018 [Go to USPTO 'Number Search'] 02.Nov.1982 to Murray Calvert, of London, Ontario, Canada, has CV of ''interlocking chains of regular pentagons in side by side abutment,'' intended for play of Chess, Checkers and Dominoes. So, Charles Gilman's ''board of genuine pentagons'' has been done before. Another one US Patent No. 3981505 ''Irregular Pentagons'' 21.Sept.1976 to Marc Odier, Paris, France, is more puzzle-mechanism device than actual CV. It improves on Odier's prior USP3608906 28.Sept.1971 and France Patent No. 1582023. Another one 14.August.1883 (125 years back) USPatent 282990 to Percy Johnson, Marlborough, Mass., USA, also has chess embodiment played on pentagonal spaces. Chess Variant Page also linked a Pentagonal chess several years ago I cannot find right away. What goes around comes around.

Only 34 Mutators in combination make over 10^27 CVs. Any CV may readily be 'dismantled', or 'deconstructed', into typical 5 to 50 constituent, 'originating' Mutators without ambiguity. Too many Mutators on one CV create awkward play. (In separate problem, too many CVs themselves existing are inherently humanly impossible to play.) Started '200-series' are new Mutators above and beyond RNs 1-32. Next starting here, '300' series ('301', '302'...) extends modes of RNs 1-32 themselves over their mere 3 to 10(usually 8) previously up to a consistent 32 ('a' to 'ff') in all cases. In other words, the corresponding 300-series Mutator 'calls' one of RNs 1-32 in order to advance modalities eventually to achieve fully thirty-two each. RN 301, Sizing, generally calls 'RN1' building on it. In furtherance of modalities, piece-arrays are set up as symmetrically as possible by agreement, with defined board sizes' rank preceding file.

After a fashion differently, there are CVs having pieces converting without Pawn promotion. In Luotuoqi (2002) Dualist Monk, Entrant 12 not adopted for the Bishop, ''can expending one move separate into one Ferz and one Wazir.'' In my '91.5 Trillion...' Comment for 'RN202m' Passed Pawns, one's opponent may re-designate a piece promoted early to different piece. Other piece-power mechanisms related to Winther's 'Rook-to-Cannon-and-back', not involving any promotion of Pawn, include: Duniho's Fusion (1999) et al., Fourriere's Pocket Polypiece (2003), Gridlock's Converter (2004), Pocket Mutation (2003), Aronson's Illusionary (2003), Battle Chieftain (2002) designating new King when King is checkmated, Novo Chess (1937) Airplane leaving the Ship by square, Big Outer (1999) pieces that similarly change type by position of squares they are on, Delegating (2002) given powers by same-side coverage, the latter really copying Betza's Chess with Inverse Capture (1997) and several other 'Betzas' [Turning, Polypiece]. Thus varying degrees of similitude. Of course, Nomic Chess (2000 here, actually 1982 such as in Doug Hofstadter 'Mathemagical Themas' 1985) interprets, adapts most any Mutator, CV.

Consisting of one(1) possible new combination(out of ten millions) of known elements(out of millions), the eight piece-types of stock compounds are all used often enough. Or two(2) since we are now permitted to substitute Rook for the poor cornered 'Dabbabah' here, that being why there are two pictures. Four of Great Shatranj's pieces, King and Knight and General and Pawn, as early OrthoChess Pawn without two-step, are unchanged from their longstanding counterparts. For new readers, General here is nothing but 800-year-old Courier Chess 'Man' appearing frequently under differing names. That leaves four(4) remaining piece-types to place, as there are no novelties in the Rules section. Prior uses of 'Minister', 'High Priestess', 'Dababba' and 'Elephant' abound before this 2006 design. Its 'Dababbah'(spelled thus differently) is, after two cases, Betza's Chess Different Armies'(1980's) Woody Rook and Lavieri's Altair's (2003) Lion Man. Its 'Elephant' is adaptation of Weijden's (1937) Novo Chess' Bicycle Unit, and the method of movement(FA) occasionally appears identically in small Chesses. Its Minister(NDW) and its High Priestess(NAF) are triple compounds that can be found in Ralph Betza's now 13-year-old Augmented Different Knights from year 1994. So, is the whole greater than sum of its parts? Not likely, instead another approximately average mishmash of pre-existing quantities, slightly further to be discounted for recency of year-2006 effort, by which time anyone should begin to know better.

So, anyone's prerogatives here being to post even average work and also to

pentile(Falcon King), fourth pentile(Chieftain), and middle pentile(GS), out of total 4000 CVs (1000 of them being Large CVs). Before he left, Fergus Duniho criticized CVPage's own Recognized list for inclusion of some 'Acclaimed' ones, as Crazy38s etc.  JJoyce and others have also panned CVP Recognized 35-40 for being obsolescent, new listings suspended again for two years. In fact, so-called 'Recognized', though historically interesting, are practically worthless as quality-CV markers. Its list is short on Large Chesses, and at least two, Grand and Omega, are among the very 'Poor', the lowest decile (10%). Of course, some out of the 40 are 'Excellent', as in most any random sample. Maybe all forty would average 6.8 out of 10. The following now add to our last Comment this thread (before Blue Queen), the three large CVs(>= 72 squares): Tetrahedral(2003), Weave & Dungeon(2002), Jester(1999). Previously, these our own selections had all-large-CVs Rococo, Maxima, Jacks & Witches, 3-Player, Gridlock(satire), Eight-Stone, Sissa, Carrera's(the first of its kind), Courier, Grand Acedrex, Gala, Jetan(science fiction also), Novo, Centennial, Chess Really Big Board, Leaping/Missing Bat, Quintessential, AltOrthHex, Ecumenical, Achernar, Altair, Hanga Roa, 4 Armies, Giant King, Insect, Nomic(various). A few, just about as good, are now casually dropped; and also couple of historical ones were really already 'Recognized', creating some overlap(as CVPage overlaps Pritchard's 'ECV'). These are put forth as falling in the top two pentiles anyway, not all necessarily Excellent, making all-around average 7.5-8.9, above the CVPage's democratically-chosen lowest-common-denominator type of inclusions.

There can be seriously but one complement to Falcon, Knight and Rook, namely the Bishop; and so on around the cycle (either way) in four-fold complementarity. Or, think of I.Q. test questions, e.g. one that sequences 'arrow up', arrow right, arrow down and then complete the pattern. '(e) none of the above' is incorrect in the instance there is an 'arrow left'. [So, complementarity existing, any such weird, inferior piece as the old Chu Shogi Lion, mentioned by 'Levi Aho', overlapping fundamental units Bishop, Knight and Rook as that one does, restricting the movements to at most two steps away, is ultimately all too inconsequential -- except in its domain of esoterica. From standpoint of complementarity, 'Chu Shogi Lion' would be in the nature of one more incorrect answer. Any number of such 'wrong' pieces can be dreamt up intellectually in infinite universe of mis-direction. One and all they can even be endlessly classified and played out, simultaneous with only those above four 'complementary' pieces able to clarify a complete and correct picture. Their particular piece-movement dynamics together are forming a sort of saddle point of convergence having in all just the one solution.]

7.7 out of 10. Very complicated and cross-references as 'Fiction'. Nice diagram 'Board and Initial Deployment'. Produced in 2005 the year after Gridlock, we take Dragon here mostly as satire. One giveaway is the number of pieces having ''no power of movement or capture.'' No one outside Gridlock's or Dragon's coterie are likely to play either. With respect for readers' time, Glenn Nicholls has cut Rules-Set articles to the two, TigerChess and Dragon. Anyone interested can easily enough master them, unlike the work of several dozen 'prolificists'. By and large, it is prolificists' bodies of work that remain out of reach by very burden of their being 15 and more separate, undistinguished Rules Sets. As examples: we are still working through potential fourth 'Joyce' CVs to Comment, no small task to do adequately with citations that author always omits. Likewise, we have not yet re-familiarized with the other 25 'Aronsons' (after evaluating Rococo, AntiKing, Horus and Illusionary). Some prolificists have even more than their 'only' 20 or 30 CVs. Staying true-to-form in style and structure, as Gilman remarks, proves nothing but hobgoblin 'consistency'. In general, one interesting, ironic effort like the present Dragon is better than yet another earnest, formulaic new-combination Rules Set. To anyone not self-absorbed in own CVs' sheer numbers, the game Dragon conveys its sense of self-parody, and even spoof, very readily -- without of course trying to comprehend all the embedded Rules and notwithstanding Nicolls' own combative denial of any such intrinsic ambiguity. The remote coherence of Dragon's Rules, obviously intentional, is diverting for a change.

Also, year 1921 science fiction novel ''The Chessmen of Mars'' by Edgar Rice Burroughs interweaves the story and the Rules of chess-form ''Jetan'' within Chapter 2 of the text and an Appendix, the famous two versions of Jetan. USA television series 1966-1969 shows ''Star Trek Chess'' in enough episodes for determining the Tridimensional Chess' Rules. Proto-Chess presented that way shows the author considers the variation important enough to think out symbolism. Presumably David Howe's Nomic Chess allows lots of room for differing interpretation that can be nailed down specifically in a given context or occurrence, almost like role-playing. Feliz Navidad.

RN 203 Flying Dutchman. Let's see, leaving off a month ago, before the Solstice, at CVs in number roughly equivalent to number molecules in the head of ordinary individual adult member of the superfamily Hominidae(be one chimpanzee or homo sapiens). The Comment 24.November.2007 proves by typical case explained, being so many in combination, that these are one and all viable, playable CVs. (a) no effect (b) Prior, each player designates one own piece-type as the Flying Dutchman and one square in the opposite back rank as the Port. Instead of checkmate, the winning condition requires one of this pre-designated piece-type to reach Port, called Weathering the Gale. Any captured F.D. returns immediately to 'Sea', namely its array square. (c) 'b' subject to F.D. being uncapturable every odd-numbered turn (d) 'b' with only F,N,B or R as F.D. (e) 'c' with only F,N,B or R as F.D. (f) 'b' subject to only R,F,Q being F.D. (g) 'c' with only R,F or Q being F.D. (h) 'b' only F or N being F.D. (i) 'b', except that, rather than a piece-type, player designates a specific piece, to be marked as Flying Dutchman. (j) 'c' as 'RN203i' (k) 'b', and the designated Port can only be in the back-rank Wide Cauldron, e.g. d1,e1,f1, & g1. (l) 'b', and the specific piece-type(F.D.) can never move backwards (laterally okay). (m) 'd' with the Flying D. unable ever to move backwards (laterally okay) (n) 'f' with 'Port-directed movements' as equivalently in both 'l' and 'm' (o) 'i', and the Flying Dutchman moves according to 'n'. (p) 'c' and 'o'. Cumulative: 2.7415776 x 10^29 CVs, approximately 48 kilograms of living tissue having that many molecules, as may be guessed, about the same as smallish human being, say the young Napoleon or Pocahontas. Later, we compare to Hydrogen atoms exclusively, which predominate 100:1, rather than these molecular aberrations -- in order eventually to achieve CVs in number greater than actual atoms in The Universe. [Would need revision in that one human has between 10^27 and 10^28 molecules not so many as 10^29, as the previous Comment begins to correct]

Dr. Milan R. Vukcevich, USA scientist and Chess Grandmaster 1937-2003
proposed this idea to USCF-types as the Future of Chess. Someone should
find his speech, the topic being Rules Changes, I think from Hawaii
convention. Considered for Nobel Prize in science of incandescence and
having lamp-related patents, Vukcevich earns GM title for composition,
like the great Sam Loyd. Now the subject matter of Chess' evolution seems
more taboo in OrthoChess circles than only 6-10 years ago, when Vukcevich
suggested ongoing Mutators, though he did not call them that, since
'Mutators' originates here with Neto in 2000. Secondly, of course in 1920's Capablanca solicited from UK open discussion of the best 'Mutators', as Pritchard's 'ECV' recounts under Capablanca Chess, and probably CVPage has produced in ten years no better ones than those eighty years ago Capablanca found.

Vukcevich's speech is about year 2002 in Hawaii, with his newest ideas
before he died;  I shall  post or quote the hard copy filed once located.
He says that, likely, Chess players will want to change the Rules
systematically (on of course 8x8) and intermittently, and that it should
be done democratically within a tournament or else from one tournament to
another for preferred 'Mutators'.   Not having read talk for five years,
I think that part keys off Fischer Random Chess, which we know to be
unoriginal. The 'democratic' process Vukcevich proposes is in error, because that would be like voting on validity of Fermat's Last Theorem, or the value of pi (as incredibly Indiana Legislature know-nothings were on verge of passing  bill 100 years ago that henceforth pi shall have value of 3.2 or so for convenience, before the 'educated' intervened -- heiring Bush and Climate)

There will be no atoms left for Presets. RN204 Relinquishment. (a) no effect (b) After Move 5, effective for Moves 6-10, player announces one own piece-type, with at least one on board, unable to move the duration. Then after Move 10 that piece-type is 'reinstated' and a different own one piece-type announced for relinquishment for turns 11-15, and so on 16-20... (c) 'b' except the relinquishment-reinstatement interval is 4 Moves (d) 'b' 3 Moves (e) 'b' 6 Moves (f) 'b' 7 Moves (g) 'b' 8 Moves (h) 'b'-mode may 'rejuvenate' the piece-type at start of any turn by sacrificing any one piece, immediately removed from board, then proceeding to move normally, including one just reinstated at option, and subject to new 'immobilization' of type only at required interval, here five(5). (i) 'c' and 'h' (j) 'd' and 'h' (k) 'e' and 'h' (l) 'f' and 'h' (m) 'g' and 'h' (n) 'h' with also two Pawns permitted to be sacrificed for such rejuvenation (o) 'n' three Pawns (p) 'n' four Pawns. Cumulative: 4.3865216 x 10^30 Alternative Chess Rules-sets. Thinking of so many molecules instead: related familially to Horses, young adult Rhinoceros (myotis lucifugus) would correspond to the about 877 kilograms that entails. Evolved 50 million years ago, venerable African Rhinos are down to 2500 individuals from recent one million. Astronomer Fred Hoyle, before he died in 2001, spoke of ''the unrealized potential of animals.'' If only, suppose instead, someone or something had just nipped Australopithecus in the bud, we would taken all together probably be better off.

RN205 Kick the Can. The King is a Can, positioned at centermost b-file square in White, i-file in Black, and cannot move. In lieu of checkmate, Kicking the Can wins, as per each modality below. (a) no effect (b) King so set up cannot move or capture. King, fully surrounded adjacently 8 ways, orthogonally and diagonally, by either side's pieces and Pawns is ipso facto 'kicked' for Checkmate. Player can self-Checkmate but it is stupid. Enemy units adjacent to King are uncapturable at all. (c) 'b' except King is able to move and capture but only in direction of the Cauldron, files e and f, whence King cannot further move (d) 'b' with 7 surrounding units able to Kick the Can (e) 'b' with 6 units effecting Kicking the King(Can) (f) 'c' and 'd' (g) 'b' with Pawns able to move, not capture, laterally one step (h) 'c' and 'g' (i) 'c', 'd' and 'g' (j) 'c' with Pawns being full Quadra-Pawns(Centennial-like) having crossed the center line once (k) 'c', 'd' and 'j' (l) 'b' and 'j' (m) 'j' these mutated quadra-Pawns cannot capture backwards. (n) 'g' and King can Kick back three times per game, meaning displacing any piece one square in the direction of the King's 'attack', with however King not moving, but the defensive maneuvre itself constituting a full turn (o) 'n', King can Kick back twice only. (p) King has the right to Kick back once only. Cumulative: 7.01843456 x 10^31 Chess Rules-sets Variations. In molecular equivalence, the largest ever Tyrannasaurus Rex improbably ever reached in weight the approximately 15 tonnes entailed.
