@H.G.,
In another comment you said "Actually it is Suicide/Giveaway that has no checking. In Losing Chess the checking rule does apply, and you lose by checkmating or baring the opponent." This page is titled Losing Chess but says that other names are equivalent: Suicide Chess, Giveaway Chess, Killer Chess or Take-all Chess. (The filename of the HTML page is giveaway.html)
According to this page, there is no check/checkmate but the rules for stalemate vary. According to the Wikipedia page for Losing Chess, the "main variant" also has no royal king and a pawn may be promoted to a king. But it also lists variant #3 with a royal king, which is also mentioned as a variant in Pritchard.
Win by losing all pieces including king, or by having fewer pieces when one player has no legal moves (FICS)

So, I guess we had a number of variants that were collectively known under a variety of names, and someone gave specific names to the specific variants? Which is a logical thing to do. This page should probably be updated, but it would be good to know more about how this happened.
