Our first game was the key one of the Zalakaros Open in Hungary, where Israel's Avital Boruchovsky was in the lead thanks to some powerful attacking chess and opening preparation, but Kovalenko managed to grab the sole lead with this win, and soon first place.} 1. Nf3 d5 2. c4 e6 3. g3 Nf6 4. Bg2 Be7 5. d4 O-O 6. O-O c6 7. b3 b6 8. Qc2 Nbd7 {We'll notice from the game selection that Kovalenko doesn't follow opening fashion and finds his own ways to get fighting positions. This variation is considered a bit passive for Black by theory, but avoids the opponent's preparation and forces him into a more strategic battle, which wasn't to White's liking.} 9. Nc3 {White decides to go for it with a quick e4, but it was better to remain flexible with} (9. Rd1 $142 {so ...Ba6 can be met with Nbd2 and ...Bb7 can then be met with Nc3. We'll appreciate the significance of this in the game.}) 9... Ba6 $1 {Now defending c4 is an awkward task and White will have to sacrifice it.} 10. Bb2 (10. cxd5 cxd5 {is already better for Black as the a6-bishop outshines the g2 prelate.}) 10... Rc8 11. e4 $6 {White plays in his usual aggressive style, but it is not appropriate for this quieter position.} (11. Rfd1 {was preferable, intending the thematic} dxc4 12.

Rfd1 Qc7 {A practical move to prepare ...e5 and also give White a chance to go wrong. We don't always have to force their decisions to induce mistakes; there's also a case for giving them enough rope to hang themselves, especially when it is clear they are bent on attacking.} (12... b5 $5 {is also possible.}) 13. e5 $2 {White overplays his hand - how can you give the knight such a beautiful outpost?} (13. Nd2 e5 14. Nxc4 exd4 15. Rxd4 Rfd8 16. Ne2 Bc5 {was fine for Black in 1/2-1/2 (56) Topalov,V (2752)-Leko,P (2737) London 2012, but sometimes in chess one has to be objective and accept that with correct play Black is not worse.}) 13... Nd5 14. bxc4 Bxc4 15. Ne4 b5 $17 {The result of White's reckless play is that he is a pawn down for nothing. But having gone all out, his only chance is to continue attacking.} 16.

Nh3 N7b6 $19 {occurred in another game - also won by Black.}) 19. h5 Na4 {Kovalenko decides that the best form of defence is to counterattack :)} 20. Bc1 {Accelerating the loss, but} (20. Qc2 Nxb2 21. Qxb2 Qd8 {would also seal White's fate, it would just be slower and more painful.}) 20... Nac3 21. Qh4 Ne2+ {Being practical, although technically} (21... h6 22. hxg6 Rh8 $1 {would force White's resignation as he loses material for nothing.}) 22. Kh2 Nxc1 23. h6+ Kg8 24. Rdxc1 Bd3 25. Bf1 Bxf1 26.

In this case, Kovalenko was trailing China's Wen Yang by half a point, and in such a must-win situation many would try to make the game as sharp as possible, but Kovalenko demonstrates that the softer approach of seeking a complex, strategic middlegame can be more effective as it generally avoids early simplifications.} 1. d4 d6 {A slightly surprising choice given that we already know Kovalenko tends to avoid memory battles in the opening.} 2. e4 Nf6 3.

Bd2 ({or} 13. Be3) 13... Kh7 $6 {Honestly I don't see how this improves Black's position, if anything it just makes f7 a weakness and lines up the king against the bishop which can hardly be good.} (13...

I've singled out two games that were particularly instrumental to this result. In the first we can learn an important lesson - the key to successfully playing for a win is not much to pick the right opening as to have the right attitude - namely, looking for ways to put pressure on our opponents and force them to make difficult decisions.} 1. c4 e6 2.
