Indeed, it automatically invokes the Diagram Designer, with default settings. For a static image that should be good enough. You can also use the Interactive Diagram as a game viewer, by including a parameter moveList= , followed by all the moves of the game. This preloads the game in the Diagram, and you can then use the buttons in the AI panel to navigate through it.

The fen of the position, as is found in chessV, is this:

3J3k1w/10/10/8p1/2P5Pp/1S7P/5s4/10/4c4j/7BK1 w - - 0 78

but I did not manage to do it. Here J stands for joker, w stands for wizard, s stands for maasai pawn. The rest are self explanatory.

This should be close enough for discussion:

And c is a chancellor, but this actually has no importance!

The short story is that black has just captured an chancellor on h10 and white is to move. The version that I have (I think is the last one published) gives now a stalemate. The long story is that any piece moved by white leads to a king capture by black in the next move. Here actually the black chancellor on e2 has a role to play. The difference from the studies we already have is that a role is played by the white joker who inherits and transmits a king (more actually a man I think) power. Is that in the second case a checkmate or a stalemate? It looks like ChessV as white has sacrificed it's chancellor for an easy draw, but is this a way for black to checkmate the opponent? And most important how should it be? I am confused by this myself. Depending on what you can do Greg, I am ready to adjust the rules in these rare cases. The most important thing is though, that the rules are clear for everybody.

Ok, diagram updated with Chancellor.

What was White's last move? The version you have doesn't have the updated rules yet, so the black joker can't move. In the updated version, the black joker will have the ability of white's last move, which could make it a checkmate if it attacks the white king. Otherwise, it is still a stalemate under the new rules. Any piece white moves would lead to white's king being in check by the black joker. Even white moving joker (imitating a king) would make black's joker imitate a king and therefore it is still check. Since white cannot move, it's a stalemate.

Agreed, but I'm not sure if it is a different stalemate.

I have no idea what you mean

No matter about my previous comment.

White's previous move was by a chancellor from h8 to h10. That chancellor got captured. I now think I know what you mean, is what's the black joker's current power. The stalemate/checkmate status depends on that. And because the last moved white piece until white moves again is a chancellor that does not attack the king. We have a stalemate here.

That's right. If white's last move was a chancellor, then it is a stalemate by either the old rules or the new rules.

And because it was facing a difficult position white decided to go for a draw. Thanks Greg!

Short follow-up on posting diagrams: You must only write the board part of the FEN between the tages; the other stuff contained in a FEN would not be expressed in the image anyway. When I place your FEN between the tags I get this:

These are not the pieces you want; apparently the standard meaning for C is Cannon, for S Squirrel, and for J it is Camel. But that doesn't have to discourage you: you can either try an alternative likely letter (like M for Marshall), or replace the letter by the full name of the Alfaerie image in braces ({berolinapawn} and {fool}:

[ fen]3{FOOL}3k1w/10/10/8p1/2P5Pp/1{SERGEANT}7P/5{sergeant}4/10/4m4{fool}/7BK1[ /fen] gives

Ok, HG, thanks!

Greg, what is the strength of the king used by the joker value evaluation?

The king has a value of 0.

I've seen a game where a pawn has promoted to joker and not to rook for no apparent reason. Any insight towards why?!

Presumably, there was some reason that was not apparent. No way for me to say.

I'll look into it more deeply hopefully!

@Greg, I have searched the source code and the documentation but I did not understood is the evaluation for the colourbound pieces pair is a bonus or a penalty. I need to know this in my bishops vs knights (for example) experiments.

@Greg,

Have you noticed my previous comment!

If you have at least one colorbound piece on each shade, there is a half pawn bonus. If you have two or more colorbound pieces on one shade with none on the other, there is a large penalty.

Thanks!

I've noticed ChessV making some obviously bad moves in endgames. Could that be due to the variation setting?
