ICC Help: Fischer-random

Fischer Random Chess (wild 22 on ICC) is a chess variant invented by Bobby Fischer. To play a game of Fischer Random Wild on the ICC, type "seek w22" to issue a seek, or "match Fred w22" to offer a game to a specific player (Fred for example).

For the initial position, White's pieces are arranged randomly by computer on the first rank, with bishops on opposite colors, and the king somewhere between the two rooks. Then Black's pieces are arranged as a mirror image of White's. Pawns are on their usual squares. There are 960 possible starting configurations, and they are each equally likely to be picked.

Castling is basically the same as in regular chess, except the king and rook may start on different squares from regular chess. The king and rook end up on the same squares as in regular chess, for example, c1 and d1, or g1 and f1 for White. All the other usual castling rules apply (you cannot castle out of or into check, squares the king passes over or onto cannot be attacked by the opponent or occupied by pieces, squares the rook passes over or onto cannot be occupied, and you can't have moved the king or rook previously).

A strange example of castling is that if your king and rook start out on b1 and a1, you can castle "queenside" resulting in the king moving to c1 and the rook to d1! But you can't make the move just by moving your king from b1 to c1, because that will be interpretted as a king move.

If your king is moving fewer than two squares when it castles, you can make the move by typing "OO" (or "oo" or "O-O") for kingside castling or "OOO" (or "ooo" or"O-O-O") for queenside castling. If you are using BlitzIn 2.6+ or Dasher 1.1.2+ you can also castle by dragging the king on top of the rook you are castling with. These methods work for any castling situation. If your king is moving two squares or more, you can just move the king and it will be understood that you intend to castle.

Versions of BlitzIn prior to 2.5 may not handle the display of castling moves correctly.
