# New variants Landing pieces from empty board: https://www.chessvariants.com/diffsetup.dir/unachess.html Generator variant, called "Matrix" ? Peces on first rank never move but generate new pieces. Pawn don't generate. A generator captured and replaced by a similar piece does not generate. King does not generate. No castling. En passant possible? Goal is still checkmate. Take(a)n(d)make : if capture a piece, take its power for the last of the turn and make a move like it. If a pawn taken: direction of the capturer. Maxima, Interweave, Roccoco Synchrone Chess: allow to anticipate en-passant capture as well :) Dynamo chess Omega chess (ask first)
