Combination chess-when a piece (not include pawn and king) capture a piece,it combines the power of the two pieces(example:a queen takes a knight becomes a piece that can move like a knight and a queen(amazon),a knight taking a knight is still a knight)
additional rule if needed:when pawn capture a piece it becomes that piece(pawn capture bishop is bishop,pawn captures rook is rook and loses the ability to capture diagonally 1 square)
another additional rule if needed:kings can combine too
