I do not see the last rule under arena and this is the reason that it is not a generalization of the regular rule Here is the descreption from Arena: "No matter where king and rook stand before castling, their target squares are the same as in normal chess. For kingside castling the white rook is on f1 and the white king on g1 after castling. For queenside castling the white rook is on d1 and the white king on c1 after castling. The terms kingside and queenside make no sense in Fischer chess, so the terms a-side and h-side castling should be used. To castle, just move the king or the rook, the move of the other piece will be made automatically. Be carefull, especially with the rook: In many cases the rook move could be legal by itself (so might be the king move). To distinguish between a normal move and castling press Ctrl on the keyboard while you make the move with the mouse. You only need to press Ctrl if you must distinguish between castling and normal move. Sometimes the king remains on the same square in the castling move. In this case you have to move the rook. Castling seems complicated, but practice shows that it is understood intuitively." > >What could be simpler or more logical? What does Arena say the rule is? See above. Uri
