My analysis of Tin - Hakimifard, Baku 2016 - A tremendous fighting game from our very young debutant.

For a change, I've decided to analyse a game between Tin Ruiqi, (Jingyao's younger sister) and the Iranian board 3, Hakimifard. Even though Ruiqi was outrated by over 400 points, she put up a great fight and was very close to holding her opponent to a very creditable draw. Unfortunately, after over 6 hours and 125 moves, she went down in flames. Still the game is quite instructive and I should mention that the Iranian coach was very impressed with Ruiqi's fighting spirit.


A game that I liked (ChessBase 13)

Bf4 Qd7 26. g4 $1 {I like White's handling of the middlegame so far. Black's f8 knight is a very poor beast and White has a straightforward plan of playing in the centre by doubling rooks, or prepare an attack with g4-g5. White was also not afraid of throwing her kingside pawns forward even though this exposes her king somewhat. At the same time, it is also extremely important to consider black's potential counterplay from the position and it is clear that her only chance lies in putting a piece on the e4 square. White has to be careful and prevent this at any cost.} Ne5 27. Kg2 { A safe move, but not especially essential. Also, the King might be safer on h2 or h1, allowing White to use the g-file for her rooks at some point.} (27. Re3 $1 {, seems strong.

Ra5 {We've finally arrived at the most instructive part of the game. A few fundamental things that we can quickly establish: 1) h3 pawn would be lost sooner or later; 2) White's rook has to remain on the a5 square where it is safely protected and guards the critical a3 pawn; 3) In order to win, Black has to force White's King into the corner, placing White in zugzwang and forcing the rook to leave its anchor on a5. Ben and I were following the game live in our hotel room and we were initially not able to achieve point 3. However, it is now quite clear that Black can place the White king in a series of small zugzwangs and then it is only a matter of time before the rook is forced to leave the a5 square. Ben then pointed out that White can always go Ra6, and goes back to a5 everytime the king is placed in zugzwang. He is right of course, and the position is drawn.} Qd7+ 87. Kb6 Kb3 88. h4 Qd6+ 89.
