In monster chess, white checkmates black when, no matter where black moves, white will always be able to take black's king by making two consecutive moves. For example, say white moves his pawn to a square that attacks the black king (where attacks means that if white makes two moves in a row, he will be able to take the black king). Black cannot respond by checking the white king with his queen in an attempt to escape mate. If black did so, white could then respond by taking black's king on his next move with his pawn before black can take white's king with his queen.
