17. Qd6 O-O-O
but black just can't castle!
Is that a program mistake?
Thank you!

No. It is not a mistake. Rook can go through covered square. Only king can not.
Ok thanks i also read this article: en.wikipedia.org/wiki/Rules_of_chess
Castling consists of moving the king two squares towards a rook, then placing the rook on the other side of the king, adjacent to it.[2] Castling is only permissible if all of the following conditions hold:
The king and rook involved in castling must not have previously moved;
There must be no pieces between the king and the rook;
The king may not currently be in check, nor may the king pass through or end up in a square that is under attack by an enemy piece (though the rook is permitted to be under attack and to pass over an attacked square);
The king and the rook must be on the same rank (Schiller 2003:19).

I had the same "problem" in one game : my oppenent said he reported me for cheating ...
Plz guys, check the rules before complaining about a possible "bug" ...

The rule is simple, one may not castle out of, through, or into check. A rook can't receive a check, so it doesn't matter.

You've played 4,452 games and didn't know this?
Grandmasters have even mistaken the castling rule so it's an easy and very common mistake to make.

"here in the heat of the battle Averbakh forgot the rules! Here is what happened according to GM Larry Evans and his book "Chess Catechism":
"Black castled queenside. Averbakh pointed out that the rook passed over a square controlled by White and thought it was illegal. Purdy proved that the castling was legal since this applies only to the king, to which Averbakh replied: "Only the king? Not the rook?"

You must contest 0-0-0[c(1,8):d(1,8)]:e(1,8):0-0[f(1,8):g(1,8)] to prevent castle. I had to check this as well when I first started playing as contesting b(1,8) does not prevent 0-0-0. Easy way to remember is you must block the path of the Kings move only (check or 2 squares either side)

Yeah, the point is that the King cannot pass or stay over a protected square in any circunstance, even to castle, he never reach one of them in your example, nothing prevents the rook from doing so that's all ok
