Best game prizes of rounds 4 and 5
Round 4
World champion Vishy Anand celebrated his 41st birthday by defeating backmarker Nigel Short to join Luke McShane (who drew with Mickey Adams) in the lead. The last game to finish was Carlsen-Nakamura, which Magnus won after five hours of play.
Round 5
Nigel Short had another off-day. He tried a sideline of the Marshall Attack (9...e4) for which Hikaru was barely prepared but the American found a very sensible continuation based on 11 g3 which suggests that this line may not be feasible at super-GM level. Short’s position after 20 Qf5 looked hopeless and so it proved.
