The seventh round of the Gashimov Memorial ended last night. The tournament leaders Fabiano Caruana and Anish Giri squared off.


With magic glasses, without purple ties

The young pretenders went for an old-fashioned line of the Open Variation of the Ruy Lopez, known since the game Keres-Euwe (Hague – Moscow, 1948), in which Keres demonstrated his brilliance. Instead of Keres’ move 16.Nbd2 Caruana preferred 16.Nd4. The players then followed the game Kosteniuk – А. Muzychuk (European Championship 2013, 1/2), until instead of 20…Nc4 Giri played 20…bxa2. After a fierce struggle the following position arose:

CARUANA - GIRI

31.e6! The only way to play for a win.
31...Rxe6? Giri had stood slightly worse throughout the game and was aiming for a draw. He probably thought that taking the pawn was the fastest route to achieving the desired outcome. In fact, the only move to hold this position is 31...Qb3! with the idea of meeting 32.Rc7 with 32...Qg3. While 32.Rc6 a5 33.e7 (or 33.Qe5 d4 34.e7 Qe3+) 33...Rxe7 34.Rxh6+ Kg8 35.Rd6 Qe3+ 36.Qxe3 Rxe3 also leads to a draw.
After this mistake Fabiano had the opportunity to showcase the strength of interplay between his queen and rook.
32.Rc8+ Kh7 33.Qd3+ Re4 34.Qf1 It would be a mistake to play 34.Qf3?, as after 34...Qb1+ the queen controls the b1-h7 diagonal: 35.Kh2 Re1!? After 36.Qxd5 the game ends in a draw
.
34...Re5

35.Qd3+? After the game Caruana admitted that he saw the move 35.Qf7! (the only path to victory!), but believed that Black could reply 35...Qa4 (preventing the с6 square from being used by the rook to deliver check) and he couldn’t see how to continue. That’s not entirely surprising: the move 36.Kh2!! (again, the only path!) is very hard to spot in this position, even for a player at Fabiano’s level. The game could continue 36…a5 37.b3! (diverting the queen) 37...Qxb3 (other continuations are no better: 37...Qb5 38.Qg8+ Kg6 39.Rc7; 37...Qd4 38.Qg8+ Kg6 39.Rc6+) 38.Qg8+ Kg6 39.Rc7.
On the other hand if White immediately plays 36.b3, without hiding away the king, Black plays 36...Qd4+ 37.Kh2 Qb6 and he is fine.
Let’s also see what happens if Black grabs the pawn with 35…Qxb2: 36.Qg8+ Kg6 37.Rc6+ Kf5 38.Qf7+ Ke4 39.Qf3+ Kd4 40.Qd1+ Ke4 41.Kh2!, again avoiding check on d4 and creating the decisive threat of moving his rook to the second rank. For example: 41...Qf2 42.Rc2 Qf4+ 43.g3 Qg5 44.Rf2! a5 45.Qc2+ Kd4 46.Rd2+ Qxd2+ 47.Qxd2+ with a win.
Strictly speaking, checking on d3 still doesn’t give up the opportunity to win, as Black could not prevent White from returning to the correct idea were Caruana to spot it
.
35...Re4 36.Qf1 Re5 37.Qd3+? Re4 38.Qf1 1/2


A draw: to whose advantage?

With two rounds left Caruana remains in front, half a point ahead of Giri. Karjakin and Mamedyarov, the latter defeating Safarli yesterday, remain their closest challengers.
