-Squatter Chess: safe on last rank = win
-Companion Chess : pieces of same nature don't attack each others
-Crossing Chess = win when the king cross half-board
-Crown Chess: place all units on move 1 (similar to Sittuyin, more freely --> in own half-board, possible pawns on 1st rank)
-Medusa Chess = Isardam
---> à chaque déplacement, check attaques directes + découvertes autour de case de départ dans 8 directions (pas caval)
-
-Kingmaker: pawns can promote also into enemy king
---> no king tracking, getCheckSquares + underCheck test all kings
-
-Eightkings: 8 pawns + 8 kings (non-royal until the last remains?)
---> yes seems better, no king tracking + no underCheck/...etc when >= 2 kings
