Alan lost his fourth round match today against GM Marin (2583). In the position below, where Marin (White) had just played 26. f5, Alan responded with exf5? Marin then played 27. Ra7+, which soon led to the loss of several black pawns. According to Rybka, 26… Rc1+ followed by …Rcc2 would be much better, and nearly equal.
Despite this loss, Alan’s rating performance over the four games is 2565. Tomorrow (Wednesday) he is White against 2713-rated Laurent Fressinet. It’s not getting any easier!
