Nc3 Nf6 5. Be2 O-O 6. Bg5 Na6 7. Qd2 e5 8. Nf3 Qe8 9. dxe5 dxe5 10. Rd1 {We have reached the diagram position. The key features are (i) The symmetrical pawn structure (ii) White has a little more space. (iii) Black has better control over d5 than White has over d4, perhaps White should have played 9.d5 (iv) White has not yet castled so Black has a slight lead in development. All things considered, the chances are approximately equal but Black has a good chance to seize the initiative. There are certainly plenty of options for Black. Option C is considered the best positional move with} Nc5 {as it centralises the knight which also attacks e4 and it has potentially other attacking ideas as will be seen in the game. If White exchanges his dark squared bishop for the knight on f6 which is a logical positional idea, the f4 and d4 squares could become a happy hunting ground for the knight on c5. Notice the black bishop remains on c8 as it is not yet clear where its preferred square is.} ({Option A -} 10... c6 {Whilst it does keep a careful watchful eye over d5 it weakens another square which White can take full advantage of with the immediate} 11. Qd6 {and with this big thorn in Black's camp, it is only White who can hope for any advantage.}) ( {Option B -} 10... Bg4 {This is positionally well founded and should be good enough to hold the balance but it is not yet clear if g4 is the bishop's best square especially as the White dark squared bishop is still on the board where it can guard d4. After} 11. O-O Nc5 12. Qc2 Bxf3 13. Bxf3 Ne6 14. Be3 c6 { when both sides have chances.}) ({Option D -} 10... b6 {This move makes a lot of sense but similar to Option B, it is not clear yet if b7 is the bishop's best square. After} 11. Qc2 Bb7 12. O-O Nc5 13. Bxf6 Bxf6 14. Nd5 Bxd5 15. cxd5 {White's pawn structure looks a little more favourable and c7 could become a target.}) ({Option E -} 10... Be6 {Possibly the weakest choice as the e6 square is not the best for the bishop. You would be correct in thinking that} 11. Nxe5 {gives Black good play after} ({However, after} 11. O-O $1 c6 12. Nxe5 {Now is the right time to grab the pawn.} Bc8 (12... Nc5 {is stronger but White is still better.}) 13. f4 {is close to winning for White.}) 11... Nc5 12. Bf3 (12. f3 Nfxe4 $1 13. Nxe4 Bxe5) 12... Bc8 13. Bxf6 Bxf6 14. Qe3 Qxe5 15. Rd5 Qe7 16. Qxc5 Qxc5 17. Rxc5 c6 {when Black has the two bishops and tremendous compensation especially as the white rook is so poorly placed.}) ({ Option F -} 10... Nd7 {There is some logic not to allow the exchange of the bishop for knight on f6 although there is nothing to fear as it further weakens White's grip on the d4 square. However, this move suggests there will a fight for the c5 square between the two knights and they might get in each other's way so it looks positionally incorrect. It also removes a defender from the kingside. After} 11. Bh6 f6 12. Bxg7 Kxg7 13. h4 {we are sure most players would take the White pieces due to the attacking possibilities}) ({ Option G -} 10... Nh5 {Similar to Option F this move avoids the exchange of bishop for knight but as Black is threatening neither Nf4 nor f5, it does not seem to be consistent with Black's plans especially as the move also removes the pressure on White's e-pawn. e.g.} 11. O-O f5 $2 (11... Nc5 12. Be3 Ne6 { is better but after} 13. g3 {White is a little better. It is still not clear what the knight on h5 is doing as} f5 {is still not the right moment to be played in view of} 14. exf5 gxf5 15. Bh6 e4 $1 {(best)} 16. Bxg7 exf3 17. Bxf8 fxe2 18. Qxe2 Kxf8 19.

Bxf6 {The game continued} Bxf6 12. Nd5 Bd8 {This is forced but it is also good.} 13. Qe3 Ne6 { This takes fine intuition and calculation by Judit who judges that she will get excellent compensation if the e-pawn is captured. This once dim knight is now eyeing up f4 and d4. Black already stands better. The rest of the game is given for completeness and although Judit did not play it totally accurately, it demonstrates the merit of playing Nc5 ahead of the other choices.} 14. Nxe5 {Not best} c6 15. Nc3 Bb6 {Black must seize the initiative before White can consolidate.} (15... Bg5 16. Qf3 f5 {is another and perhaps slightly better way of achieving this.}) 16. Qh6 Bc7 (16...

Nxd1 Qxe4 $19) 22... Bxf2 $19) 17. Ng4 f5 {This reflects Judit's aggressive way of playing but she gave it a ? in her own annotation of the game, recognising that it is not particularly sound.} (17... f6 {is safer and accordingly to Polgar objectively to be preferred.}) 18. exf5 Nf4 19. fxg6 hxg6 20.
