The 4th round of the 54th Reggio Emilia tournament saw very complicated play and three decisive games. Vassily Ivanchuk defeated Alexander Morozevich in a very tough Ruy Lopez where he emerged the better from the tactics. Anish Giri seems out of form and he made at least a couple of important tactical miscalculations on the way to losing on the white side of a King's Indian to Hikaru Nakamura, who shares the lead with Ivanchuk on 8 points. Fabiano Caruana beat Nikita Vitiugov on the black side of a rare variation of the Trompowsky. Vitiugov had long term compensation for a piece he sacrificed but dissipated this on the run up to first time control. Round 5 2pm Sat 31st Dec 2011. Caruana-Giri, Morozevich-Vitiugov and Nakamura-Ivanchuk.

Anish Giri sacrificed a piece in an effort to break down Hikaru Nakamura's King's Indian. Apparently Giri had earlier missed the line 28.Rxc5 Qd5+ otherwise he might not have played this but but it was Giri's decision to take Queen's off in a position where he had a weakened black's kingside to attack that led quickly to a lost position.

31.Qd5?!

This simplification seems bad and must have been the result of some sort of miscalculation from Giri.

Vassily Ivanchuk emerged the winner in a heavyweight Ruy Lopez against Alexander Morozevich. It isn't easy to comment on such a difficult struggle but it seems that Ivanchuk missed a direct win on move 30 but black's position remained and Ivanchuk was much better on move 40. Morozevich's piece sacrifice with 43.Bxg3 was a final try that didn't work.

Nikita Vitiugov against Fabiano Caruana was an original Trompowsky right from the very start. Vitiugov's knight sacrifice to open Caruana's king should have been good enough for dynamic equality but possibly not more. In the end the dynamic chances Vitiugov had for the piece completely disappeared on the run up to first time control and Caruana won very quickly after that.
