5. Nc3 Nbd7 6. Qc2 Bd6 7. b3 This position is very popular and had already appeared in tournaments hundreds of tournaments. Wesley So preffers to avoid Meran
7... O-O 8. Be2 e5 The idea of 8...e5 is to open the centre and get active pieces play, but instead of this Black will have an isolated pawn on d5. Other opportunities were 8....b6 or 8....Qe7. Now the most fighting move is 9.cxd5, while 9.O-O can give Black a nice play after 9...e4
9. cxd5 Now a possible variation is 9...cxd5 10.Nb5 Bb4+ 11.Bd2 Bxd2 12.Nxd2 a6 13.dxe5 Nxe5 14.Nd4 and White is slighty better but Black has nice chances to equalize after 14...Bg4
9... cxd5 10. Nb5 Bb4+ 11. Bd2 Bxd2+ 12. Nxd2 a6 The commentary of Sigeman & Co and Bazna Kings reach you thanks to the new professional chess server and the sophisticated chess outfit.
13. dxe5 Nxe5 14. Nd4 Bg4 As expected, the position with 14....Bg4 is reached.
15. Bxg4 Nfxg4 The most common result for this position is a draw, but Kramnik won against Wang Yue with Black in 2009. The game was : 16.0-0 Rc8 17.Qd1 Nf6 18.N2f3 Nxf3 19.gxf3 Nd7! and Black got a good position.
16. O-O Rc8 here there are 2 main moves : 17.Qd1 and 17.Qf5,but the first option is more popular. White has to neutralize Black's pressure on the c-file by exchanges, so White can try Qc2-d1-e2 with following Rf1-c1, but the problem is that Black has Qd8-a5 making a pressure on a2 pawn. In general,we can say that Black has enough compensation for the isolated pawn : controlling c-file+White has a weak square on c3 where Black can move the Knight (or even the Rook with the idea of doubling on c-file). So,it's probable that the fight will be around c3 square and c-file.If White exchanges Rooks,he can stay slightly better. Black can continue developing with Qd8-a5 (making a pressure on a2) or Qd8-d6 to play later Qa3 taking the control over c1 square
17. Qb2 White prevents the ideas which I mentioned above with his move 17.Qb2. From b2 the Queen is controlling the c3 square and defending the a2 pawn, also is preparing exchanges on c-file after Ra1-c1 the next move. The minus of this is that now Black can invade with 17...Ne5-d3 followed by 18...Rc8-c3. Also a negative aspect of 17.Qb2 is that now the Queen will be too far from the King's side, so now White will have to be careful with moving the rook from f1 as Black will play Qd8-h4 with double attack on f2 and h2 pawns. The move is a novelty, but gives black active play. 17...Qb6 is a typical move as well,Black has an idea to play 18...nc4 later and White can't take with a pawn on c4 as the Queen is hanging on b2. So, in my opinion major alternatives for Black are 17...Nd3 and 17...Qb6, the first option being more ambitious.
17... Qf6 An interesting choice by Black,now ideas like Ne5-d3 and Ng4xf2 are in the air. Also Black can move the Queen to h6 attacking h2 and e3 pawns (some sacrifices like Ng4xe3 are typical for this type of positions. I think,White has to move the Queen from b2 (as Black wants to play Ne5-d3 with tempo),so I propose 18.Qa3 followed by 19.h3 and 20.Ra1-c1; also 18.Qb1 with the same idea is more passive
18. Qa3 Nc6 19. Nxc6 Black is forced to take with Rook or Queen so Black still will have a position with isolated pawn.
19... Qxc6 now White's plans for next moves is to move the Knight to f3(and then probably to d4) from where it will be defending h2 pawn and preventing Ng4-e5 by Black and fight for c-file. White has a slighlty better position as Black's dynamical resources are not enough to compensate an isolated pawn.
20. Rac1 Qd7 21. Nf3 Nf6 22. Ne5 Qe6 23. Nd3 An interesting manouver by White- the Knight will be placed on f4 where it will attack d5 pawn. But at the moment Nf4 is impossible due to 24...d4!
23... Qe4 24. Rxc8 Rxc8 White is better as now White controls c-file and Black still has an isolated pawn. Black has the only idea to push d5-d4 to exchange an isolated pawn,but White can prevent it by 26.Nc5 and 27.Qb2 controlling d4 square
25. Rc1 Re8 26. Nc5 Qe7 27. Qb2 Rc8 Black has plenty of drawish resources but it's quiet unpleasant to play it with Black, as Black doesn't have any dynamical resource and has to defend passively
28. Nd3 Rc7 29. Rc2 h6 30. Qc1 Rxc2 31. Qxc2 Qe4 32. Qc3 Nd7 33. h3 Nf8 34. Nf4 Qb1+ 35. Kh2 Qxa2 36. Nxd5 Qxf2 37. Qc8 Qh4 38. Qxb7 Qg5 Precise play by black and the position remains drawish. After the time control it is logical a shake of hands to follow.
39. Ne7+ Kh7 40. Qe4+ Ng6 41. Nxg6 Qxg6 42. Qd5 Qf6 43. b4 g6 44. b5 axb5 45. Qxb5 ½-½
