This game, between two ex-experts who will probably be playing in the Westerly Chess Club Championship on September 22, is hard to explain. After the game my baffled opponent didn’t know what he did wrong, anyone would think that the isolated doubled pawns on the queenside should be weaknesses and the two bishops should be a strength. It doesn’t appear to make sense, but the computer confirms that Black seems to have an advantage.
