Nf3 d5 4. Nc3 c6 {This whole series of moves played at lightning speed was interrupted by Aronian's one-minute thought on the next one.} 5. Bg5 {In principle, the most aggressive move, but it does not disclose anything yet. According to both players' mood we could get the dynamic and strategically complex Cambridge Springs variation, the irrational Botvinnik or anti Moscow systems, but also the somewhat dull Exchange variation or (as outfashioned this might be) the Capablanca system.} h6 {With his move, Leko passes to his opponent the responsability of choosing the character of the game.} 6. Bxf6 {Aronian is not keen to check his opponent's preparation in the ultra-sharp anti Moscow variation and settles for a positional battle with some light initiative for White.} Qxf6 7. Qb3 Nd7 8. e4 dxe4 9. Nxe4 Qf4 10. Bd3 Be7 {[#]} 11. Bc2 $5 {If we except game played in 1928, this is a novelty. However, the bishop retreat is not really unusual for this line and play will eventually transpose to previous games.} ({The curious thing is that Leko thought for almost half an hour before answering, which makes me think that against the usual} 11. O-O {he did not intend to get castled, but rather tried} e5 $5) 11... O-O ({After White has cleared the third rank,} 11... e5 $2 {would run into} 12. g3 {winning the e5-pawn.}) 12. O-O Rd8 {Leko had another long thought on this natural move - a quarter of an hour. He must have felt uncomfrotable in a position he possibly did not study at home. Otherwise it is not practical to spend so much time on moves on natural moves which could be played without thinking.} ({The more natural move order is} 12... b6 13. Rfe1 Bb7 {leaving for later the decision about how to develop rooks.}) 13. Rad1 b6 14. Rfe1 Bb7 {[#]White has completed his development harmoniously and can safely claim to have stepped into the middlegame. Black still needs to open the long diagonal for his b7-bishop and find some way of putting to work his queen's rook. If he achieves that under favourable circumstances, his position will be pleasant, due to his bishops' pair. I assume that this is the kind of position making Steinitz state that the advance in development has a volatile character. The first official World Champion would surely like playing with black, due to his lack of weaknesses and potentially strong bishops. And indeed, it is not easy for White to strengthen his position in the near future. His mobilisation is so good, his pieces are so well placed that it almost looks as if he was... in Zugzwang!} 15. h4 $5 {Fortunately, White has pawn moves available, so he does not need to worsen the position of any of his pieces. Which makes me think of a somewhat naive Steinitzian advice to keep most of the pawns back, so as to have reserve tempi in the pawn ending! With his move, Aronian seems to be admitting that he cannot prevent the opening of the centre, but he uses the available time for putting pressure on the kingside. In certain cases, h4-h5 combined with Qd3 would be killing.} Qc7 $6 { This passive move is hard to understand, especially that Leko spent almost 15 minutes on it!} ({Black should not have delayed the two developing moves mentioned above:} 15... c5 16. d5 exd5 17. cxd5 Rac8 $5 {Threatening ...c5-c4, which would prevent White from setting the dangerous battery along the b1-h7 diagonal and cuase the hite queen some problems of mobility.} 18.

He must have considered the knight retreats to g3 and c3, coming to the conclusion that it is too early to define his intentions regarding the knight. White has an active position, but needs to play with precision. If his initiative vanishes, he could even get some problems, due to his} Nf8 $6 {Played almost without thinking, this will lead to a passive position.} ({Black would have had better chances to hold the position with} 18...

Bf5 Qc6 24. Ne4 {White has strong pressure.}) 21. d6 Qd7 22. Qd2 {[#]Since the dark-squared bishop cannot attack the passed pawn any more, the fight has become rather one-sided. White can increase his pressure at no risk. By now, even Wilhelm Steinitz would have to admit that, according to his own criteria, White has managed to convert his advance in development and initiative into something more palpable, more stable.} Ne6 23.

Aronian played this exchange sacrifice (truly in the spirit of the former World Champion Tigran Vartanovich Petrosian) after just one minute. The knight was the only good thing in Black's position.
