Russian Championship Super Final, Novosibirsk (8) 2016

Notes by Boris Schipkov

1. d4 Nf6 2. c4 g6 3. Nc3 d5
The Gruenfeld Defence.
4. Nf3 Bg7 5. h4








   
5...dxc4
A rare line: White attacks on the kingside at once.
6. e4 O-O 7. Bxc4 c5
Black counterattacks in the centre.
8. d5 b5 9. Bxb5 Nxe4 10. Nxe4 Qa5+ 11. Nc3 Bxc3+ 12. bxc3 Qxb5 13. h5 Qc4 14. hxg6 fxg6 15. Rh4 Qxc3+ 16. Bd2 Qd3








   
17. Bh6!
A good move. If 17. Bg5 then 17...Qxd1+ 18. Rxd1 Rf5 (or 18...e6 19. d6 (19. dxe6!?) 19... Nd7 20. Be3 Rf5 21. Ng5 Akobian ,V - Chirila, I, Dallas 2014, and Black can continue 21...h5 22. Nxe6 Bb7= with equality) 19. Re4 Bb7 20. Rxe7 Bxd5 21. Re8+= (21. g4 Rxf3 22. Bh6 Nc6 23. Rg7+ Kh8 24. Rxd5 Rh3=) 21...Kf7 22. Re7+ Kg8 23. Re8+ Kf7 24. Re7+ Kg8 25. Re8+ 1/2, a draw by perpetual check, Froewis, G - Kreisl, R, Austria 2014.
17...Qxd1+ 18. Rxd1 Re8 19. Ng5 Nd7 20. Ne6 Rb8 21. Nc7 Rd8 22. Ne6 Re8 23. Nc7 Rd8 24. Re4 Rb7








   
25. d6!?
An interesting novelty. 25. Bf4 is met by 25...Nf6 (25...Rb4= is also playable) 26. Rxe7 Rd7 27. Rxd7 Bxd7 28. Rc1, with equality in Mamedyarov, S - Giri, A, Beijing 2013.
25...exd6?!
A dubious move. Black could try 25...e5!?.
26. Ne8 Rb4 27. Re3








   
27...Bb7?
The decisive mistake. 27...Ba6 is better, 28. f3 (if 28.Rxd6 as in the game, then 28...Rb1+ 29. Kd2 Rb6 30. Nf6+ Kf7 31. Rxd7+ Rxd7+ 32. Nxd7 Rd6+ and the bishop controls the d3-square, Black takes the knight, with equality) 28...Rh4 29. Bg5 Rh1+ 30. Kd2 Rxd1+ 31. Kxd1 Rb8 32. Re7 Bb5 33. Nxd6, and White has only a slight advantage.
28. Rxd6 Rd4
Here in the case of 28...Rb1+ 29. Kd2 Rb6 30. Nf6+ Kf7 31. Rxd7+ Rxd7+ 32. Nxd7 Rd6+ White can defend the knight with 33. Rd3, winning.
29. Bg5! Rxd6 30. Nxd6 Rb8 31. Re7! Bc6








   
32. Bh6!
Three pieces attack the king and White wins quickly.
32...Kh8 33. Nf7+ Kg8 34. Ng5 Ne5 35. Rxe5 Rb1+ 36. Kd2
Black resigned. 1-0
