I recently discovered this new chess variant: Double-Reversal Chess
Rules
1. On the first move, the black player tells the white player which move to make with the white pieces. The white player must make that move. On the black player's first move, the white player tells the black player which move to make with the black pieces. The black player must make that move.
2. This continues each turn, until one side is checkmated.
3. Here's the twist. If the black king is checkmated, the black player wins. If the white king is checkmated, the white player wins.
