- When is castling possible? 6 answers
I was playing a game of chess and I was playing black. I had a rook on b2. I had control of the b1 square. My opponent white did not have any pawns in the second rank. My opponent; white castled queenside. Is it illegal for his rook to pass the b1 square considering his rook passed the b1 square I had control of. Wouldn't it make this castle move illegal on white's part?
