Is this move valid in the rollerball chess variant? Can the white King move a space to the right, into the original location of the black king? This would be disallowed in standard chess, as one cannot intentionally put themselves into check. However, in rollerball chess, moving the king into this square is supposed to end the game, giving white the win. Thanks in advance!
No it is not legal. Just like in normal chess the king cannot move into check, even if it would 'win' the game.
