Hou Yifan – Baadur Jobava 1-0
So beat Saric very easily in 28 moves in a regular Spanish and still has a realistic chance to catch up with only a half point behind the world champion. This was also a very good round for China. Ding Liren won with the black pieces an exciting game against Wojtaszek and Hou Yifan won her first game in the tournament with a good technical game versus Jobava. This will improve Hou Yifan’s self confidence before she plays the next tournament which will take place in Gibraltar.

Tata Steel Chess Tournament (11), 23.01.2015
1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nf6 5.Nxf6+ exf6 The Original Caro-Kann System is one of Jobava’s pet systems speeding up Black’s development and giving more security to his king. 6.c3
6…Qd5!? A new idea aiming to prevent White from setting up the battery with queen and bishop on the diagonal b1-h7. Compare with the following variation which is the main line in this system: 6…Bd6 7.Bd3 0-0 8.Qc2 Re8+ 9.Ne2 and here Black has three equally good moves; Konstantinopolskij’s 9…Kh8, 9…g6 or 9…h6 leading to sharp and interesting play. 7.Nf3 Bd6 8.Be2 0-0 9.0-0 Bc7 10.h3 A cautious move preventing Black from the possible set-up …Qd6 and ….Bg4 with pressure on h2. 10…Bf5 11.Re1 Nd7 12.Nh4 Be4 13.g3 Rfe8 14.c4 Qa5 15.Bd2 Qb6 16.Bc3 Rad8 17.Bg4 Nf8 18.Re3
18…c5? A huge positional error. Better was 18…g6 and …f5. The main idea with the whole system is to set the kingside pawns in motion. Black does not need to fear 19.c5 which make it harder for White to exploit the pawn majority. Black’s position is fine after 19…Qa6 with the idea 20.Be2 b5 19.d5 After giving Hou Yifan a protected passed pawn her merciless technique will decide the game. Hou Yifan is very strong in advantageous positions where she can rely solely on positional technique. 19…Bg6 20.Qe2 Rxe3 21.Qxe3 The exchanges of the major pieces one by one are definitely in White’s favour considering that White is working with an extra pawn on the queenside. 21…Bd6 22.f4 Qc7 23.a4 Qb8 24.Re1 Bc2 25.Bd1 Bxd1 26.Rxd1 Qc8 27.Kg2 Re8 The e-file means nothing when there is no break through to consider. Black’s temporary control will actually only lead to further exchanges later on. 28.Qd3 Ng6 29.Nxg6
29…fxg6?! 29…hxg6 was the normal and correct recapture followed by …g5 activating the pawn which was originally on h7. 30.b3 Kf7 31.Re1 h5 32.Rxe8 Qxe8 33.Bd2 Hou Yifan steadily improves her position with every move and will continue Kf3 and g4 if Black does ”nothing”. 33…b6 34.a5 bxa5
35.Qe3! 35.Bxa5?! would unnecessarily have allowed 35…h4 This idea was one of the advantages (except giving the king on g8 an active square on f7) recapturing with the f-pawn but it’s easily prevented with White’s move. 35…Qd7 The exchange of queens 35…Qxe3 36.Bxe3 and Ke7 37.Kf3 Kd7 38.g4 hxg4+ 39.hxg4 does not minimize White’s advantage. 36.Bxa5 Qf5 37.Be1?! 37.Bd2! was safer giving more support to the f4-pawn. 37…h4! 38.g4 Qc2+ Both 38…Bxf4 39.gxf5 Bxe3 40.Kf3 Bd4 41.fxg6+ Kxg6 42.Bxh4 and 38…Qxf4 39.Qxf4 Bxf4 40.Bxh4 would have led to advantageous bishop endings for White. 39.Kf1? 39.Kg1 Kf8 40.Bxh4 a5 41.Bf2 a4 42.bxa4 Qxc4 43.a5 Qxd5 44.a6 with a clear advantage was the correct continuation. The a-pawn would have been exceptionally dangerous.
39…Kg8?? An unbelievable mistake. Black just gives away a whole piece for nothing. 39…Kf8 40.Bxh4 a5 followed by …a4 would most likely have led the game towards a draw. In this variation it turns out that the White king was wrongly placed on f1. 40.Qe6+ Kh7 41.Qxd6 Qxb3 42.Kg2 Qxc4 43.Qe6 a5 44.f5 gxf5 45.Qxf5+ g6 1-0
