Tikkanen Accepts Giri's
Pawn Sac With 14.cxb6
Round 5
(Analysis by William Stewart)
Sigeman 2011 ended yesterday night with a 3-way tie for first: Wesley So, Anish Giri, and Hans Tikkanen. Giri and Tikkanen faced off today, with Giri attempting to win the tournament outright by playing an aggressive variation of the Grunfeld as black. Giri sacrificed a pawn with 11. ...b6!? to gain counterplay on the open c-file, however Tikkanen was able to neutralize black's initiative through multiple exchanges to achieve a R+N endgame with an extra pawn. Giri's active pieces compensated his material deficit and he was able to regain the pawn and hold the draw.

Round 4
(Commentary by GM Stellan Brynell)
Anish Giri and Jonny Hector followed the first round game between Shirov and Hector. In the twelfth move, Hector diverged with 12...Rd8 instead of 12...Nc5. The middle game was interesting, Giri won a pawn but Hector had compensation with his active pieces. Hector's bishop was especially strong considering White's pawn on g3 and the weakened white fields around his king. In time pressure, Hector did not find the correct continuation and ended up one pawn down in the endgame. But he was never in danger of losing since Giri could only manage to get a rook ending with three pawns against two on the same wing. Giri tried for some time to play for a win, but in the end he had to concede the draw.

Round 3
(Commentary by GM Stellan Brynell)
All the games in the third round were drawn but still contained a lot of interesting chess.
Alexei Shirov avoid Anish Giri's Russian Defence by playing 2.Bc4. After the interesting 11.c4, Shirov created problems for Giri and some exchanges later they entered a rook and knight endgame with an extra d-pawn for Shirov. At this point, everybody expected Giri to suffer for a while before perhaps making a draw. But only ten moves later Shirov could no longer keep his extra pawn and the players agreed to a draw. In hindsight, it is easy to say that Shirov should have refrained from advancing his d-pawn so quickly.

Round 2
(Commentary by GM Stellan Brynell)
Nils Grandelius got good play with a positional pawn sacrifice as Black in an English game against Anish Giri. According to Grandelius, his big mistake came in the 26th move when he played Rfd8. The correct continuation would have been to defend the e6-pawn (and in some variations stop White's bishop from reaching e7) with 26...Rfe8 and only then target White's weak pawns. In the game, Giri could consolidate his material advantage and with a steady hand win the game.

Round 1
(Commentary by GM Stellan Brynell)
Anish Giri defended with the Slav against Wesley So. The Dutch player got an isolated pawn on d5 but had compensation in form of his active pieces. The equilibrium was never seriously disturbed and when almost all the pieces had been exchanged (only the queens remained on the board) the players agreed to a draw.
