Solution


Annan chess: Units move normally, unless they stand one square directly in front of another unit of their own side, when they take the powers of movement of that piece. An example game: 1. h2-h5 (moves like a rook) f7-e6 (moves like a bishop) 2. d2*d7+ (moves like a queen, gives check because after the move it regains its pawn-powers) Ke8-f7 3. c2-g6# (moves like a bishop, gives check because it regains its pawn powers. The black king moves like a bishop, so it can't escape, and h7 moves like a rook so it can't capture the pawn on g6. So this is mate).
