Twinmove Chess (uncompelled)
This page contains one or more presets for playing a game online with Game Courier, an online server for playing Chess variants by correspondence.
The positional laws of chess are fully valid in the uncompelled variant, although the double-move creates interesting tactical possibilities, both in defense and attack. The missing en passant move facilitates the defense, as a counterweight to the forceful attacks occuring in this chess variant. Note that a pawn can promote to queen and immediately move, since it satisfies the condition of pawn move + piece move. Don't give up if you're losing material. There are many opportunities for counterattacks in this game. Somewhat surprisingly, this is a sophisticated and fully functional form of chess.
You can use point & click to move. After a pawn move the turn will remain with the same player. Castling and promotion are automatic (the player will be asked about promotion piece). Note that it's against the rules to make two pawn moves in a row (the preset doesn't check this).
