{SP 242 Before the game for a moment I wanted to switch the Black kking and
queen. It seemed so strange to see them in the wrong order.} 1. e4 e5 2. Nf3
Nf6 3. Bc4 {In a game's database on chesstigers.de I found one game between 2
engines which started the same way but in this position White chose} (3. b3 Nc6
4. Bb5 b6 5. d3 Nb4 6. c3 Nc6 7. Qe2 O-O-O 8. O-O Bb7 9. b4 Nh5 {
with unclear position}) 3... b6 {In Chess960 the pieces development plays even
more important role than in regular Chess. In chess960 pieces are not placed
as harmonically as in the regular chess, so if you can finish your development
faster than your opponent you can get quite a big advantage.} (3... b5 $5 {
was interesting since it could have given Black a few very important tempi} 4.
Bxb5 Nxe4 5. Qe2 Nd6 6. Ba4 f6) 4. Nc3 Bb4 5. d3 Qe7 {too shy} (5... d5 {
was more ambitious} 6. exd5 Nxd5 7. Nxe5 f6 8. Nf3 Qg6 9. Bxd5 Bxd5 10. Nh4 Qf7
{two bishops give Black a strong compensation for the sacrificed pawn}) 6. a3
Bxc3 7. Qxc3 d6 8. b4 O-O 9. O-O c6 {although the idea of d5 looks logical in
this position the strong idea that White played on the next move could have
tried by Black as well} (9... Nh5 $5 10. Rfe1 c5 {with unclear play}) 10. Nh4
$1 {White uses that the Black's bihsop on a8 is too far from the king's side
and there is no way to prevenet the knight's invasion on f5 since Black can
not play g6 since it opens the a1 bishop after f4.} Nd5 {although I didn't
like my position here I understood that I have to go for complications
otherwise White will win too easily} 11. Nf5 Qg5 12. Qe1 Nf4 13. g3 d5 {
looks far too risky, but White has to decide concrete problems which is not so
easy in a 20-minutegame} 14. h4 (14. Bxe5 {was also pretty strong} Nh3+ 15. Kg2
dxc4 16. f4) 14... Qh5 ({After} 14... Qg4 {I didn't like} 15. f3 Qh3 16. Rf2 {
and the queen is in a trap}) 15. Qd1 $2 {White didn't handle the pressure} (15.
f3 {was the strongest move here. White threatens to play g4 and Ne7 winning
the queen so it is not clear how Black can continue the fight.} Rce8 (15...
Rfe8 16. gxf4 dxc4 17. Qg3 Qg6 18. Qxg6 hxg6 19. Nd6) (15... f6 16. gxf4 dxc4
17. Qg3 {the bishop on a1 will get into the game soon and Black will not able
to do something against the strong f5-knight and the strong-a1 bishop}) 16.
gxf4) (15. gxf4 Qg4+ 16. Kh1 (16. Ng3 exf4) 16... Qf3+) 15... Qxd1 16. Rfxd1 $4
{the final mistake in this match. Kateryna told me after the game that she
simply forgot that her rook on c1 would be hanging} (16. Rcxd1 Ne2+ 17. Kh2
dxc4 18. Ne7+ Kh8 19. Nxc8 Rxc8 20. Bxe5 {
was the best choice, that lead to an interesting endgame}) 16... Ne2+ 17. Kf1
Nxc1 {the rest is easy} 18. Ne7+ Kh8 19. Nxc8 Rxc8 20. Rxc1 dxc4 21. dxc4 c5
22. f3 Nc6 23. b5 Nd4 24. Kf2 f6 25. Ke3 Rd8 26. a4 Kg8 27. a5 Bb7 28. Bc3 Bc8
29. g4 Be6 0-1
