Bundesliga onward

The team with the most stellar members, Baden-Baden, gained another victory in the 9th round of the Schachbundesliga which took place on Sunday. They beat Hamburg 6-2. 

Alexei Shirov's game on the 2nd board turned out to be quite interesting. 

SHIROV (Baden-Baden) - HUSCHENBETH (Hamburg)
Bundesliga 2011/12

Sicilian defence
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5 e6 7.f4 Be7 8.Qf3 Qc7 9.O-O-O Nbd7 10.g4 b5 11.Bxf6 Nxf6 12.g5 Nd7 13.f5
In this line, which was actively played since 1980's, t
he vast majority of the games (3,5 thousand!) continued with 13...Bxg5+ and 13...Nc5.



13...O-O!?
This rare line has been played by Ju Wenjun 
three times - against Kosintseva sisters and Alexandra Kosteniuk. Huschenbeth himself faced it playing against Vladimir Hamitevici in 2010.
14.f6!?
That is the most natural move. However, it's hard to find any serious game where White has applied that move. 
14...gxf6 15.gxf6 Nxf6
In the case of 15...Bxf6, White will answer with 16.e5.
16.e5 dxe5 17.Nc6
One of the typical "Sicilian" knight's jumps. 



17...Kh8?!
Here young and gifted German player overcomplicated things. After 17...Bb7! 18. Qg3+ Kh8 19.Nxe5 Black can play:
a) 19...Bd6 20.Rxd6 Bxh1, where White's only chance to play for a win seems to be 21.Rd1 with a sharp position.
b) 19...Bd8!? 20.Rxd8 is also worth of analysis.
18.Nxe7 Qxe7 19.Qxa8



19...b4!?
Maybe Black originally expected to play 19...Bb7 20.Qa7 Ra8, and then 21.Qg1 Rg8 22.Qa7 Ra8 with the repetition leading to a draw. However, 21.Qe3! Bxh1 22.Qxe5 instead of 21.Qg1, leads Black to worse position.
20.Qb8!?
That is enough for retaining the advantage. Later Shirov allowed his opponent to gain real counterchances, but ultimately he managed to win.

20...Nd7 21.Qc7 bxc3 22.Qxc3 Qg5+ 23.Kb1 Bb7 24.Bxa6 Bxh1 25.Rxh1 Nf6 26.h4 Qf4 27.Re1 Rd8 28.a3 Qd4 29.Qc7 Rd7 30.Qxe5 Qxe5 31.Rxe5 Rd4 32.h5 Nd7 33.Ra5 Kg7 34.b4 f5 35.c3 Rd6 36.c4 f4 37.c5 Rc6 38.Bb5 Rc7 39.Bxd7 Rxd7 40.c6 Rf7 41.Rc5 f3 42.Rc1 f2 43.Rf1 1-0
(Mikhail Golubev's commentary).

Levon Aronian's Berlin team improved its position by defeating Trier. Aronian outrplayed David Howell.

Bobras (Trier) - Maksimenko (Berlin) duel on the fourth board finished in White's favor. The result became predictable after Ukrainian GM was caught in a trap, which is known after the recent game played at the Gibraltar tournament.
