It was a good week for the higher-rated youngsters against their "seasoned" opponents, as both Anish Giri and Baadur Jobava won their matches with undefeated +3 scores. When we left off after round 4, Giri was up two and Jobava up one, so it's clear that the last rounds didn't go well for the veterans.
Both matches were decided in round five. For Shirov, it was decided in a surprisingly negative way: with White he went down a well-known theoretical path to a perpetual check - he just gave up! This uncharacteristic move on his part sealed match victory for Giri, who did not return the favor in round 6. But we'll get back to that later. Timman-Jobava was much more exciting, with Timman offering a rook and then a knight in pursuit of an attack. It was creative; unfortunately, his best opportunities had come earlier in the game, and by this point Jobava had the advantage. He defended well enough and eventually converted his extra exchange.
In the final round, the youngsters won twice. Giri and Shirov engaged in a heavyweight theoretical battle in the Sveshnikov Sicilian. My surmise is that Giri had everything prepared until around move 30, by which point Shirov was simply lost. (That's not as implausible as you might think, considering that Shirov's novelty only came at move 25 in a very well-traveled line, and as that novelty was the computer's top choice there's little reason to think Giri hadn't examined it beforehand.) The youngster simply prepared better, and nowadays that can be enough. As for Timman, his 17...d5 was a dubious decision, inviting a strong exchange sacrifice. After that Timman could hope for no more than a draw if he could successfully grovel, and that was not to be.
