The fourth round of the Tal Memorial was very exciting, with three decisive games out of five - and it could have been five out of five. Anish Giri defeated Peter Svidler with Black to take sole possession of first with 3.5/4. He is half a point ahead of Ian Nepomniachtchi, who drew with Levon Aronian. For the most part this was a correct result, except for an Aronian blunder on move 15 that went unpunished.
The other draw was a marathon battle between Evgeny Tomashevsky and Shakhriyar Mamedyarov. Early on Mamedyarov had an edge, but later Tomashevsky wasn't just better; he was winning. He missed his chances, and in the end Mamedyarov scraped out a draw.
Boris Gelfand did his best to try to eke out a draw against Li Chao, hoping to create a fortress against Li's superior forces, but he couldn't do it. Finally, Vladimir Kramnik bounced back from his loss in round 3 with a good win over his longtime rival Viswanathan Anand. He was pressing throughout the first time control, but without ever being too close to a win. In the second time control, however, his pressure bore fruit. Kramnik did make one subsequent mistake, but Anand failed to seize his chance and lost several moves later.
