i saw fusion chess yes, i just thought of something smaller you know..just one piece fusing with others..and the rest remains ordinary chess..(i dont know some ideas come close to unplayable or to 2 rules away of a yugioh fight.)....
as for the server i thought that hijacked pieces could be replaced by others but now i see its gonna need movement coding..so no worries i just thought to share the idea...
Another idea for a chess variation..i think its simple and kind of fun.
PARASITE QUEEN or PIGGY BACK QUEEN
Queen moves like a king..
Queen has the ability to mount/dismount friendly and enemy pieces(mount and dismount are considered a turn)
FRIENDLY PIECES
the piece now MOVES (together with queen) using its own moves OR the queen moves (1 square all directions)
this new piece can CAPTURE using only the mounted piece moves
if the piece is captured queen goes down with it
queen CAN CAPTURE enemy pieces during dismount
ENEMY PIECES
queen attaching herself to an enemy piece now controls this piece
lets say your BLACK queen hijacked a WHITE rook
it CANNOT CAPTURE its fellow white pieces and CANNOT BE CAPTURED by its fellow white pieces....basically you hijack an enemy piece and move it to your part of the board to bring it to a more risky position..off course during dismount it can escape...
you CAN use it to capture your own pieces and you can CAPTURE it with your own black pieces but queen, if not dismounted, goes down with it
it moves ONLY with the moves of the piece hijacked
BOTH KINGS of the game CANNOT get hijacked
queen exists in PAWN PROMOTION
....i believe i covered everything..have fun and if i missed something plz comment........................also death to castling
