Long castle bug

Please link the game. The system definitely generaly allow casting with the b-square under attack, so either there is something else in the game you are talking about (like the a rook moved, and then return to its starting square), or its a bug specific to that individual game/setup (in analysis, you can also adjust casseling rights in board setup).

Maybe because you have already played with your king or rook?

A counterexample:

where white castles long with b1 attacked by black bishop.

@ZuriBru said in #1:

I was analysing a game and the system does not allow a long castle with white, as the b1 square is under attack, however the other squares are not. According to FIDE rules, castling is allowed in this situation.

I am pretty sure that the b1 square under attack was not the reason - what makes you think so?

As others have said, please link the game and tell the move number. This surely can be explained.

According to FIDE rules, castling is allowed in this situation. I am pretty sure that the b1 square under attack was *not* the reason - what makes you think so?
