So, Wesley (2744) - Jobava, Baadur (2713) [A40]
ACP Golden Classic, Bergamo (6) 2014

Notes by Boris Schipkov

1. d4 e6 2. c4 b6 3. e4 Bb7 4. Bd3








   
4...Bb4+
The alternatives are 4...f5 and 4...Nc6. A slightly strange opening: White has a strong pawn centre.
5. Kf1
Another move is 5. Bd2.
5...Be7 6. Nc3 d6 7. Nf3 Nf6








   
8. g3!?
A logical novelty: White plans Kg2. After other two moves White also had a small advantage due to a space preponderance: 8. h3 Nbd7 9. Be3 e5 10. d5 Nc5 11. Bc2 a5 12. b3 O-O 13. Kg1 Ne8 14. a3, Zhu, C - Grabuzova, T, Moscow 2010;
8. Qe2 h6 9. g3 Na6 10. a3 (10. Kg2) 10...c5 11. d5 O-O 12. Kg2, Peschardt, S - Borwell, A, Sweden 1999.
8...O-O 9. Kg2 Nbd7 10. Qe2 c5
Or 10...e5 11. d5 (11. Bc2!? Re8 12. Rd1) 11...c6 12. dxc6 Bxc6 13. Nh4 g6 14. Bh6 Re8 15. b4 a5 16. a3, with a small edge to White.
11. d5+ Re8 12. Rd1 Bf8 13. dxe6?!
White opens the diagonal for the black light-squared bishop. 13. Qc2 is better.









   
13...fxe6?!
However Black also chooses the wrong response. Here Black can activate all his pieces with the strong 13...Rxe6! and after 14. Qc2 g6, followed by ...Bg7, the bishops put pressure on the long diagonals to secure counterplay.
14. Bc2 a6 15. Bf4 Qc7 16. Rd2 Ne5 17. Rad1 Bc6
Or 17...Nf7 18. Ng5 Nxg5 19. Bxg5 Be7 20. Kg1.
18. Bxe5! dxe5 19. Ba4!
Wesley So trades the light-squared bishops to get a small but lasting advantage, because the white knights are better than the bad black bishop and knight, and the doubled e-pawns are a weakness.
19...Bxa4 20. Nxa4








   
20...b5?
Risky, 20...Be7 21. a3 h6 22. Nc3 Rab8 is more stubborn. Black tries to counterattack with a pawn sacrifice, because does not want to defend his position for many hours. Live fast, die young!
21. cxb5 axb5 22. Qxb5 c4?!
After 22...Nxe4 23. Re2 Nd6 24. Qxc5 Qb7 25. b3 e4 26. Ne5 e3+ 27. f3 Nf5 28. Qc4 White is better.
23. Rc2! Rec8 24. b3 Qb8 25. Qxb8 Raxb8 26. bxc4 Nxe4 27. Nxe5 Rb4 28. Nb2 Nc5








   
29. f4!
White defends the knight in the centre, an outpost, winning thanks to two extra pawns in the endgame.
29...Be7 30. Nbd3 Ra4 31. Nxc5 Rxc5 32. Rb1 Rc8 33. c5!








   
33...g5
Or 33...Rxc5? 34. Rb8+ Bf8 35. Rxc5, and White wins. 33...Bxc5? is met by 34. Rxc5 Rxc5 35. Rb8+ Rc8 36. Rxc8#, checkmate.
34. c6 Bd6 35. Nd7 gxf4 36. Nb6
The fork.
36...f3+ 37. Kf2
Black resigned. 1-0
