Value of castle preventing
Hello all,
SO I was playing the other day, and I made a move; can't quite remember the exact details, but I ended up losing a bishop, but in doing to, forced my opponent to move his kingside rook, thus preventing him from being able to castle. So my questions are: 1: was this a good exchange on my part, and 2: if so, where would you draw the line when it comes to pieces you would be willing to lose to keep your opponent from being able to Castle. Thanks :) |

Without being a strong chess player, I'm pretty confident the answer here is going to be "it depends". But it's not worth sacrificing a bishop unless you have a huge attack ready to unleash on the uncastled king. How volatile was the position?

Unless you have a very forcing, immediate attack, this is usually not worth it. But as always, "it depends."

Not very. It was early in the match, and I think I just overvalued preventing my opponent from castling. |

just setup a position, allow castling, leave houdini on for a few minutes. then uncheck the castle allowed and see how the evaluation changes.

Normally, material is quite important so if anyone is sacrificing even a pawn, there must some form of compensation. Usually, if a sacrifice of a piece is sound, there is a strong attack resulting in either checkmate or getting back the sacrificed material ( or most of it ) with a decent position; that's why it's important to analyze positions to some depth. Now I realize you're just starting out, but it would help you considerably to practice tactical exercises, no matter how easy/difficult they are and make notes where you tend to overlook possible candidate moves, so practice, practice, practice!
When players are < 1800, it's simply important to hold on to your material ( not hang pieces, pawns, etc. ); of course, if you're up material after the dust has settled ( there's no tangible threats, etc. ), you may need some technique to convert whatever material/positional advantage(s) there are. You can't sacrifice even a pawn if after the initiative peters out, you're just left with a bad ending or a position where the natural course of events will lead to one. Usually, the material advantage of two pawns is decisive and being down a piece for almost nothing is considered losing; exceptions will include endings/fortresses/closed positions. |

there are some openings that sacrificing a piece to keep the king in the middle of the board is a good play. some lines in the king's gambit for example. however, it is definitely better to hold onto the material in general.
