Pawn peculiarities

Castling

A King that has not moved before can move two squares in the direction of a Rook that has not moved before, in which case that Rook is moved to the square the King skipped over. This is only allowed if all squares between King and Rook are empty.

General rules

Differences with FIDE

The King is not special in any way, and can be captured like any other piece. Hence the concept of 'check' does not exist. Pawns can promote to King.

Strategy issues

The King is actually a good choice for a promotion piece, as it is not so easy for the opponent to feed a lot of material to a King.
