Play online chess |  Subject: End game question
Message:
I have an endgame question, I don't expect anyone to work this out for me, but perhaps its part of chess doctrine somewhere and someone knows the answer off the top of their head. I was in an endgame where I had knight and rook, my opponent had bishop, rook and pawn. I got a fork on his bishop and pawn (both protected) and took the pawn, figuring it would be hard to get an attack going against a rook with just rook-bishop. My opponent blundered and we drew, but the question is should I have taken the pawn or the bishop, or neither perhaps? I did set the board up after the game and push the pieces around, I couldn't really force the issue with the bishop-rook combo, but I'm not so good in the endgames either.

Of course it all depends on the position, but statistically, both options lead to a high probability of a draw.
In Rook+pawn vs Rook endgames, if the inferior side can get his king on to the pawn file in front of the pawn, it's usually a draw (Philidor's position).
In Rook+Bishop vs Rook endgames, the inferior side can usually draw by keeping his king and rook close together so as to avoid skewers and pins that would lose the rook. Keeping the rook off the squares of the same color that the superior side's bishop controlls helps (to cut down on possible bishop pins and skewers). In this endgame, the inferior side also has an additional resource in that he can play for the exchange of rooks.
As a practical matter, if I saw that my king could get in the path of the pawn easily, I'd play into the Rook+Pawn vs Rook endgame rather than the Rook+Bishop vs Rook one simply because there's a smaller chance of blundering and losing to a tactical shot in the former endgame.
By the way, all Rook+Pawn vs Rook endgames and Rook+Bishop vs Rook endgames are solved.

KRB vs. KR is almost always theoretically a draw, but among weaker players, if the 'stronger' side is prepared, then there are excellent practical chances to win. It is possible that insufficient losing chances can be claimed in this position--although most arbiters will probably reject this claim.
KRP vs. KR, on the other hand, can be either a win or a draw. However, if the position is drawn, then the stronger side has no practical chances and the game is drawn without much play. The weaker side can draw easily if he can reach the Philidor position, whereas the stronger side can win easily if he can reach the Lucena position.
So, this is a purely subjective decision, dependent on the position :)

Aronian Wins the Last Amber Chess Tourney — Levon Aronian won the Amber chess tournament in Monaco this month. He will be known as the last winner. After twenty years, the combined blindfold and rapid chess event, featuring the world's top players, comes to a halt. Named after his daughter Melody Amber, the Dutch sponsor Joop van Oosterom, created a dream tournament for the world's best grandmasters, allowing them to have fun and be well paid for it. This year's prize fund was 227,000 euro (aprox. US $317,000). Last year's co-winner, Vassily Ivanchuk, went as far as calling it " the greatest tournament." It was a perfect chess event to watch: a nice mixture of different creative efforts from brilliant and funny ...

Magnus Carlsen continues chequered form with Vasily Ivanchuk defeat — This week's Amber blindfold and rapid invitational in Monaco had a massive €227,000 (£199,000) prize fund and was the last in a 20-year-series financed by the Dutch computer billionaire Joop van Oosterom. The top eight in the world chess rankings all took part, and despite its artificial conditions, Monaco is a real test of strength for the chess elite. Magnus Carlsen had declared in a pre-tournament interview that he would restore the dominance he has spoilt with uneven results over the past year. The Norwegian, 20, took an early lead until in round five, in a bizarre repeat of Amber 2010, he was crushed by Vasily Ivanchuk in both games. In the rapid game he actually got checkmated, but the damage was ...

Chess world rocked by French cheating scandal — Three top French chess players have been found guilty of cheating in last year's world championship, using an ingenious messaging system. The French chess federation has suspended Sébastien Feller, a 20-year-old grandmaster, his team-mate Cyril Marzolo, 32, and Arnaud Hauchard, 39, the French team captain. It said they used mobile text messages, a remote chess computer and coded signals to beat the opposition. The fraud, which took place during last September's Chess Olympiad in Khanty-Mansiysk, Russia, has rocked the chess world, which prides itself on its code of honour. Rival teams have been known to accuse each other of cheating, but in this case the whistle-blower was ...
