Notes by Boris Schipkov

1. d4 Nf6 2. c4 e6 3. Nf3 Bb4+
The Bogo-Indian Defence.
4. Bd2








   
4...c5
An interesting line. The main alternatives are 4...a5 and 4...Qe7.

Also playable is 9. Qd3 b6 (or 9...Re8) 10. Nbd2 Bb7.

Or 10. axb4 Nxb4 11. Nc3 Qc7 (11...b6) 12. Rc1 (12. Qb3, 12. b3) 12...Bd7 (12...Qxc4?! 13. Ne4 Qa6 14. Nxf6+ gxf6 15. Nd2 d5 16. e4, with compensation for the pawn) 13. Nd2 Rfd8, with counterplay in Meier, Georg - Anand, Viswanathan, GRENKE Chess Classic, Baden-Baden 2013.
10...Qc7 11. Rc1
Other moves: 11. h3, 11. Qc2, 11. e3 and 11. Ne1.

12. Ne1
Or 12. e3 b6 13. Ne1 Bb7 14. Nd3 Bxg2 15. Kxg2 bxa3 16. bxa3 e5.








   
12...e5!
Black has good counterplay.
13. Nd3?!
13. Nc2 is more precise, 13...Qb6 (or 13...Bd7, here 13...Bf5?! is worse, 14. Ne3 with a small edge to White) 14. dxe5 dxe5 15. Ne3 bxa3 16. bxa3 Qb2 17. Nd5 Be6 18. Qc2 Qxa3 19. Ra1 Qf8 20. Nxf6+ gxf6 21. Bxb7 Ra7 22. Bxa6 Rxa6 23. c5 Qe8, with equality.
13...Bf5!
Black provokes e2-e4 and then f2-f3 that these pawns obstruct White's light-squared bishop.
14. e4
White could try 14. Re1 or 14. axb4.
14...Bg4! 15. f3 Bd7








   
16. axb4
16. Qe2 is somewhat better.

Black begins to push his pawns forward.
23. Nd2
Or 23. Nd6 c4 24. Qxa7 Rxa7 25. Rfd1 Nxd6 26. exd6 Ra2 27. Rb1 Rc8, with a clear edge to Black.
23...c4! 24. Qxa7 Rxa7 25. Rfd1
If 25. Rf2 then 25...Rda8 26. f4 Ra1 27. Nb1 Nc7 28. Rd2 Be8 29. Kf2 Kf8.








   
25...Be6!
Threatening ...Rad7.
26. Nf1 Rxd1 27. Rxd1 c3 28. bxc3 bxc3 29. Ne3 b4
Black easily wins thanks to his two nice connected passed pawns on the queenside.
30. Bf1 b3 31. Rd8








   
31...g6!
Poetic. Prosaic is 31...Bd7 32. Bd3 Kf8.
32. Rxe8+ Kg7 33. Bd3 Rd7! 34. Bb1








   
34...Rd1+!!
Black sacrifices the rook to queen his pawn.

After 36. Bxc2 bxc2 37. Rd8 c1=Q, queening and winning.
White resigned. 0-1
