Andreikin: Today's winner in Biel

Maxime Vachier-Lagrave and Anish Giri had the longest game today, but neither of them ever looked like breaking the deadlock. Both players have had to settle for four draws so far.
Dmitry Andreikin's convincing win over David Howell was the only decisive result in the fourth round.

It was top against bottom in the fourth round where Negi opted for a solid Queen's Gambit and managed to achieve a drawish rook ending to earn his first half-point.

Tomashevsky acquiesced to a quick draw as Caruana was about to fully equalize with ...c5.

Giri against Vachier-Lagrave started in lively fashion but simplification led to a solid position where there was nothing much for either player.

Nguyen pressed with his Reti (New York) but Rodshtein obtained enough counterplay.

Dmitry Andreikin	RUS	2650	1-0	David Howell	ENG	2616	30

Andreikin's win came from a Neo-Grünfeld (where White fianchettoes his king's bishop) in which Black seemed to get his pieces tangled up. Howell avoided material loss but had to allow White's rooks onto the seventh rank with devastating consequences.

The Russian now moves up to equal second.
