1. c4 Ng6 2. b3 {A good idea for white, like I mentioned in an earlier game, the bishops are strong.}

2… c5 3. Ng3 b6 4. d4?! {possibly premature. Maybe e3 and then d4, maintaining the pawn center. It’s not that big a deal, but I do have an extra pawn in the center now. (D & E for me vs E for white)}

4… cxd4 5. Bxd4 d6 {e6 might allow c5 for White, so d6 first.}

6. Be4!? {interesting decision by white. Makes sense though.}

Bxe4 7. Nxe4 e5 {This might look counter-intuitive, based on my now weak d6 pawn, but my potential center with e5 and f5 most likely makes up for that. There are similar positions in the
mainline Najdorf.}

8. Bb2 f5 9. Nc3 O-O 10. Nd5 {maybe Nd3 with idea of Nb4, clamping down on d5 is good. If I stop this with a5, then b5 is weak, as well as d5.}

10… Nce7 11. e3 Kh8! {This move is good in that I’m planning to rid myself of my weakness by playing Nxd5 Qxd5 Ne7 and d5. Notice Qxd5 is not check now.}

12. Ne2 {Maybe Nc3, simply retreating, is better. Then my knights are kind of stepping on their toes. They both want to be on e7, and my d-pawn isn’t going anywhere.}

12… Nxd5 13. Qxd5 {If pawn takes, then d6 is covered and black can turn his attention to the king side.}

13… Ne7 14. Qd2 d5 {mission accomplished!}

15. O-O-O? {This move is bad, as White c-pawn will now be isolated at the very least. Much better is cxd5 and then after Nxd5 white might castle short or possibly long, as his king will be safer than in the game.}

15… dxc4 16. Qb4 Qc8 17. bxc4 Nc6 {with Na5 to come, most probably winning the c-pawn.}

18. Qc3 Na5 19. Ba3 Rf7 20. c5 Qa6 {Things are getting dangerous for white. Nc4 is a problem (not to mention white’s hanging knight), and white’s king is wishing he were on the other side of the board!}

21. Qd3 {I’m not sure what else.}

21… Nc4 22. Bb2 Qxa2 {So yea, this is probably resign-able. White’s king is getting ambushed, and he is down material.} { White resigns } 0-1

SP883

1. Nf3 (I would like to distinguish starting positions of chess960 into 2 groups-ones that are more “natural” and the others, that are more “clumsy”. This one is certainly one of the latter group for black, so it requires especially precise play from him. Pawns on a7 and f7 are unprotected and especially the f7 pawn is very problematic, since white has an immediate threat of Ng5 (or Ne5) and it is not so easy for black to find a natural way of defending against it.)

1… g6! (I think this is the correct approach-black opens the h8-bishop, prevents the move Ne5, while in case of 2.Ng5Nh6 white actually wouldn’t prove anything. Much worse would be, of course, 1…f6?, closing totally the bishop on h8 plus losing the possibility of later developement of the knight to f6.)

2. d3 (White is already pointing his queen’s eye to the h6 square, where black’s knight might be in the near future.)

2… d6 3. g3 (It was to early to go for 3.Ng5?!Nh6 4.Nh7?Ng4 and black is winning, but not 3…Qf5? 4.Ng3! and black is on the ropes.)

3… Nd7? (But this is a mistake, since now white will really get what he wanted at the very start. Instead, black had 2 decent options-the solid 3…Ne6 with approximate equality, or the sharp 3…b6, which can lead to big complications after 4.Ng5Bh1 5.Nf7Kd7 6.Nh8 with unclear play.)

Game25a

 

 

 

position after 3… Nd7?

 

 

 

 

4. Ng5 Nh6 5. Ne6+ (Probably it was even better to take the pawn by 5.Nh7Ng4 6.Qf4, but I wanted to have the activity of my pieces.)

5… fxe6 6. Qxh6 Nf6 7. Ne3 Qd7 8. b3?! (I wasn’t sure whether this move is really essential, or could I just castled here, because 8.0-0Qa4(?) worried me a little. Well, actually white can now play 9.b3 and on no account can black take on a2-it would simply cost to many tempo. Therefore the move 8.b3?! is actually a loss of time, since white will play b4 in a moment. The advantage, however, stays clearly with white, since black has a problem not only with his somewhat spoiled pawn structure, but also with his bishop on a8.)

game25b

 

 

 

position after 8. b3?!

 

 

 

 

8… O-O-O (Hardly any better would be 8…b6 9.Ba8Ra8 10.0-0Kc8 (What else?) 11.c4Kb7 12.b4, etc.)

9. c4 Kb8 10. O-O Rg8 11. b4?! (This move belongs into white’s plan, but, speaking concretely, much better would be to play here 11.Qh3!e5 12.Qg2, avoiding what could have happened in the game.)

11… Bg7?! (This “natural” move gives white a definitive advantage. It was worth trying 11…e5, preventing the retreat of Qh3 and intending to continue with g5 and Rg6, harassing white’s queen, even though white will be able to play Nd5 at the right moment, exchanging knights and making possible the queen to retreat to h5, still preserving the advantage.)

game25c

 

 

 

position after 11… Bg7?!

 

 

 

 

12. Qh3 e5 13. Qg2! (Unusual set-up for white’s queen and light-squared bishop, but now black can open up his a8-bishop only at the cost of serious weakening of his pawn structure, which actually happened.)

13… Qc6 14. Qxc6 bxc6 15. a4?! (And this is already the first step into the wrong direction-white prepares b5, but this brakethrough is the wrong one (Why to open up black’s a8-bishop and also exchanging black’s c6-pawn, which is a weakness??). Instead, white should aim for the c5 push, but in that case pawn stands better on a2, preserving the possibility of the defense of the b4-pawn by means of a2-a3. So, after 15.c5, followed by Rfc1, Nc4, Na5, white would have had an overwhelming advantage.)

game25d

 

 

 

position after 15. a4?!

 

 

 

 

15… Kc8 16. b5?! (White is very consistent in carrying out his wrong play, but it is also true that here 16.c5 is less strong (but still the way to go!) than on the previous move: 16.c5Kd7 17.Bg2Rb8!? 18.Nc4Nd5 19.Bh3e6 with some annoying counter-play, although concretely here white has 20.b5! and black is still in deep trouble.)

16… Kd7 17. Nc2?! (Better was 17.Bg2 with the idea of 17…c5 18.Bh3 and f2-f4, still with some annoying initiative.)

17… cxb5 18. axb5 (From practical point of view, more dangerous for black would be 18.Rb5!?Bh1 19.Kh1Rb8 20.Rfb1Rb5 21.Rb5Rf8!? 22.f3!?, with the idea of Nb4 and Rb7-white’s initiative is still unpleasant, but black can hold with precise play.)

18… Bxh1 19. Kxh1 c6? (The better freeing pawn move was 19…a6 and after 20.ba6?Ra8 21.Nb4Rgb8, followed by c7-c5 and equality. More promising for white is 21.b6cb6 22.Rb6 with an advantage, but black as well has an earlier improvement: 19…Ra8! 20.Nb4a5! 21.Na6…(21.ba6 transposes into 19…a6, with equality.) 21…c6 with totally double-edged play.)

20. bxc6+ Kxc6 21. Nb4+ Kd7 22. Na6! (This prevents Rb8 and thus prepares Rb7.)

22… Ra8? (It was absolutely essential to play 22…Ke6 even though after 23.Rb7Rd7 24.Rfb1 black cannot avoid the loss of the a7-pawn.)

23. Rb7+ Kc6? (This allows mate, but black’s position is lost even in case of 23…Kd8 24.Bc3, or 24.Nc7, etc.)

24. Rc7+ Kb6 25. Rb1+ { Black resigns } (It’s easy to see the mate in case of 25…Ka6 26.Rc6Ka5 27.Bc3Ka4 28.Ra6mate, but in case of 25…Ka5 the finish is more pretty: 26.Nc5!!dc5 27.Bc3Ka4 28.Rcb7 (Or 28.Rc5a5 29.Rcb5 with mate to follow.) with the unstoppable 29.Ra1mate, although the prosaic 26.Bc3 mates even 1 move quickly: 26…Ka4 27.Rcb7 with the following 28.Ra1mate, or 26…Ka6 27.Rc6mate.) 1-0
