Twinmove Chess (compulsory)

This page contains one or more presets for playing game online with Game Courier, an online server for playing Chess variants by correspondence.

In Twinmove Chess (compulsory) the double-move consists of a pawn move followed by a piece move, which are both mandatory. The pawn moves are compelled, until there exist no more pawn moves, when the pieces can continue moving without being preceded by a pawn move. Should a pawn become free to move again, it is compelled to move. Note that a player, when the king is threatened, can make a pawn move before taking measures to protect the king. He can also make a pawn move that discloses his king to an enemy piece, but he is well adviced to protect his king in the subsequent move. The en passant rule does not exist, simply because a pawn move cannot occur prior to the opponent's turn. Note that it is capture of the King that counts, not checkmate. Otherwise the rules are the same as in orthodox chess.

What makes this game so interesting is that pawn moves are both for good and bad. It's not always advantageous to move a pawn. This circumstance creates a strategical tension in the game. Pawn moves often cause irreparable damage to the position. To be forced to make that extra pawn move could sometimes be regarded a punishment, rather than a reward. 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. When a pawn is moved the turn remains with the same player. Castling and promotion are automatic (you will be asked about promotion piece).

Note! The players must themselves verify that the player makes a pawn move when a pawn is free to move (the preset doesn't check this). They must also verify that a player doesn't make two pawn moves in a row, which is not allowed.
