1. c4 Nf6 (Since I’ve noticed that we are playing the same position as in the previous game and that the first move was also the same, I didn’t want-already from psychological point of view-to repeat the move from that game (1…Ng6), although it’s also perfectly playable.)

2. b3 Ng6 (There was a threat of Bxf6 and Bxh7.)

3. Nf3 b6 (It is more essential to open the bishop on a8 than to castle short-black in fact didn’t castle in this game-so I did it right away.)

4. Ng3 Nf4?! (Interesting position: I didn’t want to castle yet, because white’s bishops are looking towards black’s kingside and besides the position of the knight on g6 worried me in connection with possible advance of the h2-pawn. But probably black could have castled here, since it’s not clear what white is doing in case of 4…0-0 5.h4Nf4, or 5.e3Bf3 6.gf3Nh4. Another possibility was to play 4…c5, playing symmetry. But people are usually reluctant to follow symmetry with black pieces, when it’s not really necessary. Sometimes even when it’s necessary.)





Position after 4… Nf4?!





5. Rg1?! (In fact white could have castled here after all. I intended to continue then with 5.0-0h5, but after 6.d4! white pushes back black’s knight, or even shuts down black’s a8-bishop in case of 6…c5 7.d5, so that all black’s activity looks premature.)

5… d5 (At first I wanted to play here 5…c5, but I didn’t like the variation 6.Bf6gf6 7.Bh7Bf3 8.gf3Rh8 9.Bb1Rh2 10.Nh5!? (not that it is necessarily bad for black!) while castling again seemed dubious to me: 5…0-0?! 6.d4 and black has problems.)

6. Bxf6 gxf6 7. cxd5 Bxd5 8. Be4 Qb7?! (This leads to some problems, since due to the position of black’s queen on the long diagonal white can now go for the h7 pawn. Thus, the simplest solution was just 8…Be4 9.Ne4c5 and black is alright.)






Position after 8… Qb7?!




9. d3 c5 (The knight on f4 was hanging plus at some point black needs to open up his bishop on b8.)

10. Bxh7! e6 (Of course, 10…Bf3? 11.gf3Rh8 12.Be4 doesn’t help black.)

11. Be4 f5 12. Bxd5 Qxd5 13. Qc4 Qd7 14. a4 Ke7 (Having in mind possible transformation into some endgame, black “castles in the center” and connects his rooks. However, despite the fact that white cannot castle short anymore, it is by no means clear whether black has sufficient compensation for the pawn.)

15. Qb5? (Black’s predictions about some endgame have immediately come true! But this move is careless, since it allows serious weakening of white’s pawn structure on the queenside. Instead, white should have been more cautious and play 15.Nf1!, followed by g3 (pushing black’s knight away from active square f4 and then continue with Ne3, Kf1-Kg2, artificially castling and connecting his rooks with it.)





Position after 15. Qb5?





15… Qxb5 16. axb5 Nd5 (And already there are threats of Nc3 or Nc7.)

17. d4? (It was better to allow the pawn on b5 to be taken than to open up the center with the inactive rook on g1.)

17… Nc3 18. Rc1 cxd4 19. Nxd4 Rxd4 20. Rxc3 Rfd8 (White has managed to avoid direct loss of the b5-pawn, but black has now huge compensation for the pawn: white’s Rg1 and Ng3 are totally out of play and white’s queenside pawns are still very weak. Therefore, black already has serious advantage.)

21. f3?! (Preventing Rd1mate and trying to activate the g1-rook by the help of Kf2, but at the same time weakening dark squares. However, the passive 21.Rc1-intending e3-is also unlikely to be the saving opportunity.)

21… Be5! 22. Rc4? (This loses right away. 22.Rc1 should have been played anyway.)

Rd1+ 23. Kf2 Bd4+ 24. e3 Bxe3+! 25. Kxe3 Rxg1 26. Rc7+ Rd7 27. Rc2 Rb1 28. h4 Rxb3+ 29. Kf2 Rxb5 30. h5 f4 { White resigns } 0-1

1. g3 g6 (Just like in the traditional chess, in chess960 we also want our queen to be open as quickly as possible. Due to its great influence on the battle. But-as in traditional chess-we don’t want to get out with our queen to early-especially if all the opponent’s pawns are protected and there are no targets to attack-since we don’t want our opponent to get some extra tempo by attacking it.)

2. Nc3?! (It was more natural to play 2.d3Bg7 3.Bd2 and only then maybe Nc3)

2… Bg7 (Now due to the pressure on c3 white cannot easily develop his bishop on c1 which also means that he is having a hard time to castle. However, in this game I have decided to play “highly originally” from the very start, so this didn’t bother me too much.)

3. Nd3 (This early “cavalier set-up” cannot be to promising for white, since there are no weak spots in black’s position that could be attacked/occupied by white knights. But also nothing would be achieved by 3.Nd5Nc6 and then e7-e6.)

3… e6 4. a4 (Activating the rook on a1-what else to play?)

4… d6?! (The best way of exploiting white’s clumsy set-up was to just play 4…d5-unlike white, black can still put some pawns in the center!)

5. a5 a6 6. Ra3 Bd7 7. Bg2 Bc6 8. Rb3 Kc8?! (Probably it was better first to include exchange of bishops: 8…Bg2 9.Qg2Kc8!? and black enjoyes solid, “hedgehog” position.)

9. Bxc6?! (We don’t want to exchange pieces when the other side has lack of space, so 9.e4 was a serious alternative.)

9… bxc6? (Serious positional mistake-now the a6 pawn is weak. In case of the correct 9…Nc6 I intended to sacrifice the whole rook: 10.Rb7!??Kb7 11.Nb4d5 and now, of course, also temporarily the knight by 12.Ncd5Nb4 (Or 12…ed5 13.Qd5, attacking only with the queen and the knight, with unclear position.) 13.Nb4Kb8 14.Nc6Kc8 15.Ne7Kd7 16.Qa8Ke7 17.Qa6 and I considered 3 pawns to be enough for the piece, but in fact after 17…Nd6 black has significant lead in development plus those 3 extra pawns are in front of the white’s king, so they cannot easily be advanced. Therefore in this position black is somewhat better.)





position after 9… bxc6?





10. Nb4 d5 (This also weakens the c5 square which will later prove to be decisive, so I was more expecting 10…Kd7. But it is also true that then black’s knights will remain passive for some further time, especially the d8-knight, so that without the communication between his rooks and with the weaknesses on a6 and c6 black shouldn’t be able to hold the position.)

11. Na4?! (Probably premature direct occupation of the c5-square; it was time to put some pawns in the center, so that 11.e3 should have been played, followed by d2-d4, making sure that white’s bishop will get out too one day plus taking over the control of the c5 square anyway!)

11… Bd4?! (This move speeds up white’s developement. Instead, black had a nice opportunity to go into the counter-attack with 11…Nd6, followed by N6b7 or Nc4-white is still not very well developed and his pawn on a5 is undefended at the moment!)

12. e3 Ba7 13. Nxa6 Bxe3? (Here it was much better to just play simply 13…Nb7, after which I intended to sacrifice the exchange by 14.Rb7Kb7 15.N6c5Bc5 16.Nc5Kc8 17.a6?!, but this pawn on a6 can actually easily turn out to be weak, so that better is 17.b4 with very good compensation for the exchange.)





position after 13… Bxe3?






14. dxe3 Rxa6 15. Bd2 Nb7 16. Qf3? (It wasn’t clear to me how white can improve the position after 16.Rb7!Kb7 17.Nc5Ka7 18.Qf3Nd6 19.Qe2Nb5 but here 20.c4! should do the job.)





position after 16. Qf3?






16… Qf6 (Not 16…Na5? 17.Ba5Ra5 18.Qf7Ra4?? 19.Qe6Kd8 20.Rb8mate.)

17. Qe2 Ra8 18. a6 Nbd6 19. Nc5 (In the heat of the battle I simply didn’t notice that here white can finally castle-19.0-0! with the decisive positional advantage. How pleasant is to castle after all that drama?)

19… Nb5 20. Rxb5 (Of course, white wants to brake through, while now after 20.0-0Ned6 black could still put up some resistance, even though white’s advantage is overwhelming-he has a clear plan of putting the bishop on b4 and opening up the center by f3 and e4, whereas black has no real coordination between his rooks and no serious counter-play. But, anyway, I again didn’t notice that castling is possible for me.)

cxb5 21. Qxb5 Nd6 22. Qb7+! Nxb7 23. axb7+ Kb8 24. Nd7+ Kxb7 25. Nxf6 Rgd8 26. Bb4 Ra4 27. c3 h5 28. Kc2 Kb6 29. Be7 Rda8

30. Nd7+ Kc6? (Final mistake. However, after 30…Kb5 31.Ne5 white should also win in the long run.)

31. Ne5+ Kb7 32. Nxf7 Kb6 33. Ne5 c5 { Black resigns } 1-0
