RandomVisitor: From a recent essay by Stuart Rachels:
Changes in chess perception are typically gradual. Sometimes, however, you can experience rapid shifts. In the last round of the 1987 U.S. Open, I accepted an early draw offer from Grandmaster Lev Alburt. The position was dead equal, we were about to swap some pieces, and I did not expect to beat my famous opponent. Afterwards, when I looked at the final position with my trainer, Boris Kogan, Boris said, “Of course you are a little worse here.” “Why?” I asked. “Because your b-pawn is weak.” “No, it isn’t.” So we played it out. Twenty moves later, Boris had captured my b-pawn with his knight, and I was sure to lose. So we played it out again, and the same thing happened (except this time, he captured my pawn with his king). Boris had convinced me he was right, but more amazingly, he had changed my perception of the position. The black pawn now looked weak to me. I could now see what Boris had seen.
The game should continue 13…axb5 14.Rxa8 Bxa8 15.dxc5 and then black can recapture the pawn in either of two ways. <typo here, Stuart means 14...axb5 15.Rxa8, etc.>
