Hi, i was playing as white and my opponent castled queen side next move (0-0-0). is this not illegal, i was clearly covering the b8 square to stop castleing. or am i going mad , since im covering squares between rook and king castle 0-0-0 should be illegal
illegal 0-0-0? please advise
Sort:
It is a legal move as the king isn’t moving through check. I was over forty when I learnt this rule so don’t worry, it’s a tricky one.
Perfectly legal since it's the rook that is moving through the attacked square and not the king.
ah i see now!!! thanks guys very much. and yes this is a very valuable lesson learned. thanks again for clarification, much appreciated, i was racking my brain for sometime during the match and after, to be honest it really threw me.

You got away with one as instead of 0-0-0 there was Bxd3. eg.Qxd3 Qxf4 winning a piece.

Hm...Bxd3 cxd3 Qxf4 Qxe6+ Be7 black has a piece for a pawn. Slightly awkward for black I guess but I'm not sure there's enough compensation.

I don't remember who it was, but years ago I read about a grandmaster summoning the tournament director over to his board because his opponent had castled long in this kind of position. After the director explained the rule to him, the GM said "So, just the king--not the rook too?"

Not true. What about Bxd3 Qxe6+ straight away? White looks better after Bxd3.

Maybe. Bxd3 Qxe6+ Qxe6 Rxe6+ Kf7 Ng5#. So Bxd3 Qxe6+ then either Qxe6 Rxe6+ Be7 or Be7 straight away. Then cxd3 white is up a pawn but its not a great pawn.

You're referring to Averbakh vs Purdy. Purdy was astounded when his famous GM opponent doesn't seem to know the castling rule. See this blog post where this case is given as Question #4: Do Grandmasters Know The Rules Of Chess?
