New Game: Split-Brain Chess

[donkirkby]

Play as partners. Each turn, both players write half a move in secret, then reveal them to be combined. One player, the chooser, chooses a piece to move. The other, the mover, chooses a direction and distance by writing an arrow on a grid of squares. When the two halves are revealed, the mover moves the chosen piece as close as possible to the written direction and distance. The move must be a legal chess move. If more than one legal moves are the closest possible, the mover may choose whichever they prefer.

A castling move is considered moving the king two spaces toward the rook.

Probably want to group the moves, maybe in groups of 4, and allow talking between the partners at the start of each group. Put a stack of 4 checkers at one corner, then move a checker at the start of each turn for White. When the turn starts with a stack of 4, partners may talk.
