External Link: Seirawan Chess

In Seirawan Chess, invented by GM Yasser Seirawan, the rules are the same as in orthodox chess, except that two pieces, the Elephant (Chancellor) and the Hawk (Cardinal), are placed in the reserve. Whenever a piece leaves its initial square, one of the extra pieces can immediately be introduced to the vacant square. So this is a double move, comparable to castling. Should a player refrain from inserting his extra pieces at these occasions, then he has forfeited his chance of introducing them. When castling, one of the extra pieces can be placed on either of the squares left vacant, namely the corner square, or the e1/e8 square. As the board is smaller than in Capablanca's Chess, the situation is easier to control, and there are less pawn weaknesses. The knight retains its strength on this standard board.
