Dark chess

A player does not see the entire board – only their own pieces and the squares that they can legally move to.

The goal of this chess variant is not to checkmate the king, but to capture it.

[2] For playing over-the-board, three chess sets and a referee are needed, just as in Kriegspiel.

There are some minor differences in the rules on different servers: Generally, because basic Dark chess rules are universal with respect to its "parent" classical variant, any 2-player chess variant may be played "in dark".

In this variant, a king should be carefully protected from very dangerous checks by invisible pieces; castling is essential, as the pawns and rook protect the king from invisible pieces.
