This game, created by Fabrice Liardet, is an original chess variant with simple rules but a deep strategy. The basic rules are identical with the classic Chess but there are several significant exceptions:
Instead of clicking on piece to move and then on a destination square, a player marks a destination square and submits this unfinished move.
Then it is up to the opponent to choose which player's piece will actually move to the marked square (of course, only the pieces which really can make a move to the destination square can be selected). When it is done and the move is completed, the opponent marks a square to move his/her own piece to, etc.
If only one piece can move to the marked square, the full move is performed immediately without waiting for the opponent's choice (because there is only one possibility).
If a pawn reaches the last row, it is the opponent who chooses which piece the pawn will be promoted to.
Castling is not possible.
There is no check or checkmate. The goal is, like in Dark Chess, to capture the opponent's king.
