Marin on Tromso R2 – round two selection

[Event "41st Olympiad Tromso 2014 Open"] [Site "Tromsø"] [Date "2014.08.03"] [Round "2"] [White "Nyback, Tomi"] [Black "Carlsen, Magnus"] [Result "1/2-1/2"] [ECO "D11"] [WhiteElo "2594"] [BlackElo "2877"] [Annotator "Marin,Mihail"] [PlyCount "71"] [EventDate "2014.??.??"] [EventCountry "NOR"] [WhiteTeam "Finnland"] [BlackTeam "Norwegen"] [WhiteTeamCountry "FIN"] [BlackTeamCountry "NOR"] 1. d4 d5 2. c4 c6 3. Nf3 Nf6 {An interesting choice of the opening. Carlsen has played the Slav in the past, but it is by far not his main weapon. The puzzling thing is that in a game where the big rating difference strongly required to play for a win, he exposes himself to a transposition to the symmetrical structure resulting after 4.cxd5 cxd5. The Exchange variation is not as dull as it seems and players like Botvinnik or Portisch have made good use of it with white, but Black has his reasons for content, too. Objectively, he should be close to equalizing, which actually is just one preliminary step on the way towards taking over the initiative.} 4. Qc2 {(!) Played almost without hesitation. I assume that Tomi was not really bothered by the idea of a draw (although I may be wrong), but even though the exchange variation makes part of his repertoire, he does not show himself ready for such early relasing of the tension.} dxc4 5. Qxc4 Bg4 6. Nc3 Nbd7 7. e4 {[#]} e5 $5 {Quite typical for Carlsen. He takes the game into almost unexplored territory as soon as on move seven! He had been doing that during the match against Anand quite a lot, depriving the then reigning champion to display his massive preparation.} (7... Bxf3 {is played almost unanimously, with 7...e6 a minor alternative.}) 8. Nxe5 Nxe5 9. dxe5 Be6 10. Qd3 Ng4 11. Qxd8+ Rxd8 12. Bf4 $1 {White prefers returning the pawn in the near future for the sake of completing his development} ({If} 12. f4 Bc5 {Black's initative becomes threatening.}) 12... Bc5 13. Bg3 Bd4 14. Rd1 Bxe5 15. Rxd8+ Kxd8 16. Bxe5 Nxe5 17. f4 Ng4 18. Be2 Nh6 19. Kf2 f6 {[#]The game has entered Carlsen's predilect territory - the endgame. Much to his praise, White keeps playing with ambition and even manages to put some pressure on his mighty opponent.} 20. h3 Nf7 21. Bg4 Ke7 22. Bxe6 Kxe6 23. Rd1 Rd8 24. Rxd8 Nxd8 {[#]The structure is quite similar to that from the last match game against Anand. Even though in Chennai Carlsen was black, inboth cases, he had two groups of three pawns each, against his opponent's two plus four. But in the current game, White's position is a bit more active.} 25. b4 Kd6 26. Ke3 a6 {A somewhat mysterious move. The threat of b4-b5 was not real, as it would allow . ..Kc5, but Carlsen might have intended to but his queenside majority into motion with ...b5 and ...c5, or even ...c5 right away.} 27. Na4 Ne6 {Renewing the threat ...b5..} 28. f5 $1 {A committal decision after only five minutes of thinking. White gives away the e5-square, but gets some queenside pressure in exchange.} Nd8 29. Kd4 Nf7 30. Nc5 {It may seem that the weakening move ... a7-a6 is about to cause some major problems. But Carlsen is not that easy to catch on the wrong foot in the edngame.} b6 $1 {Played instantly.} ({If} 30... Nd8 31. a4 {threatening a4-a5, Black would soon be in Zugzwang. Actually, even now the best saving chance would be giving up the apwn with} b6 {under lesss favourable circumstances already.}) 31. Nxa6 Ne5 {The black knight has occupied the fantastic central square, while his rival has no obvious way back into the game.} 32. a4 Nd7 {Threatening ...c5, which would open the king's way towards the knight. The final move repetition took place rather quickly, although White twice took a minute for refelction.} 33. Kc4 Ne5+ 34. Kd4 Nd7 35. Kc4 Ne5+ 36. Kd4 1/2-1/2

O-O {[#]} Qe8 $5 {A rare move, trying to step out of the heavily analysed variations.} ({It would make little sense to go for the Mar del Plata attack with:} 7... Nc6 8. d5 Ne7 {Kramnik is a leading expert of the Bayonet attack initiated by} 9. b4 { a line with which he managed to "convince" Kasparov abandoning his beloved King's Indian!}) 8. dxe5 dxe5 {[#]} 9. b4 $5 {Kramnik played this relatively rare move instantly. The same as in the aforementioned variation, he starts the queenside attack on the first given occasion.} ({The main variation is} 9. Be3) 9... Qe7 {After having managed to clear matters in the centre, Black needs regrouping in order to resume the process of development. It is worth mentioning that starting with this move Black spend big amounts of time on almost every move.} 10. b5 a6 $146 {A new and probably not very inspired move.} ({Previously,} 10... c6 11. a4 Rd8 {was played.}) 11. a4 axb5 12. cxb5 Rd8 13. Qc2 {[#]From a very general perspective, the consequences of the queenside operation favours Black, who has exchanged his rook pawn for a more central one. But this would apply only if he was better developed. With respect to the lines with ...c6 instead of ...a6, the queen does not have the c7-square at her disposal and the d5-square is not defended properly.} Nbd7 {Black obstructs the bishop, a piece that, sadly, wil not get the chance for developing in this game.} ({With hindsight, it is easy to recommend} 13... Bg4 {followed by ...Nbd7, which would also put up some fight for the d4-square.}) 14. Ba3 Qe8 15. Rfd1 {[#]White is fully developed and exerts strong pressure along files and diagonals. Black is very passive and his move choice is strongly limited.} Bf8 $6 {Strategically, it is right to exchange these bishops, but concretely Black loses a pawn. But, as Tarrasch would say, in bad positions all moves are bad. Hm, or was it Tartakower?! Whoever he was, I can only agree with him!} 16. Bxf8 Nxf8 ({Or if} 16... Qxf8 17. Nd5 Nxd5 18. Rxd5 { Black lsoes either the c7- or the e5-pawn.}) 17. Rxd8 Qxd8 18. Nxe5 Qd4 19. Nf3 Qc5 20. Qb2 Ng4 21. Nd1 $1 {This apparently passive retreat annihilates Black's initiative. White is a pawn up, has the safer king and more active play. Black is lost without even having got out of the opening, as some of his pieces are still on their initial squares.} Nd7 22. Rc1 Qb6 23. Nd2 $1 {More knight retreating, preparing for the final assault.} Nc5 (23... Ngf6 {could be met with} 24. Ne3 Rxa4 25. e5 {with a decisive attack.}) 24. Nc4 Qf6 $2 { Shortening the agony.} 25. Bxg4 ({And in view of} 25. Bxg4 Qxb2 26. Ncxb2 $1 { (attacking the c5-knight)} Nb3 27. Bxc8 {with decisive material gains, Black resigned.}) 1-0

Nf4 h5 18. a4 {[#] The last two moves are symmetrical, but the impact of White's move is stronger, as it threatens opening the queenside at once.} g5 $1 {Doubtlessly Judit's favourite move (together with g2-g4). In her games, the resolute advance of the g-pawn may have all kind of tactical or strategic aims, such as gaining space or weakening the enemy structure. In this case, she intends to clear the h2-b8 diagonal in order to continue the attack with ... Ng4.} 19. axb5 $1 {But White does not cooperate and bravely sacrifices a piece for the sake of speeding up his own attack.} gxf4 20. bxa6 Bc6 21. Bxf4 Rdg8 {The position looks completely chaotical.

Rf3 Ka8 27. h3 {[#]} Rhg8 {It is hard to evaluate this move. Objectively, it is not entirely sound, but in a practical game it is the kind of guarantee for brilliancy.
