Anand - Yeoh Li Tian
Round 1.2, 4.9.2017
World Cup 2017
1. e4 c6 2. d4 d5 3. e5 Bf5
The Caro Kann Advance Variation. Li Tian once again play his pet opening. Recently he did play he Ruy Lopez Berlin Defense as black but probably he did want to "fight" against world's elite powerful opening database.
4. Nf3 e6 5. Be2 Nd7 6. O-O Bg6 7. Nbd2 Nh6 8. c3 Be7 9. Nb3 O-O 10. Bd3 c5
Compare to the French Advance variation, black has manged to solve his light square bishop problem by playing Bf5 early in the game and eventually exchange it with white's minor piece. However, in this line, black spend to tempi to play c5.
11. Bxg6 hxg6 12. h3 Rc8 13. g4 c4
Decades before this move is taboo and label anti positional because in this type of structure, black usually will not" lock " the queen side where he has more space. Computer later proved that this type of move is playable and humankind "follow".
14. Nbd2 f6
In a must win situation, Li Tian need to create some counter play, he can't sit tight and do nothing. Black open the f-file for his rook at a cost of slightly damaging his pawn structure . Black's e6 and g6 pawn can be a potential target later.
15. exf6 Bxf6 16. Re1 Rc6 17. Nf1 Nf7 18. Bf4 Re8
It seems that Li Tian's is not interested with the half open f-file for time being.
19. Re3 Be7 20. Qc2 g5 21. Bg3 b5 22. Rae1 Nf8 23. R3e2
I don't understand this move. Probably Anand want to play Ne3 later.
