nummerzwei: Evgeny Najer is a great player, but he has conveyed the impression of being overplayed and unstable for rather a long time now.
Today he lost a miniature to Aleksander Mista in the Czech league:
Mista, Aleksander (2583)- Najer, Evgeny (2646)
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 7.Be3 e6 8. g4 h6 9. Bg2 g5
<Danailov's move, which was played in the world class game Judit Polgar vs Topalov, 2006 and has been played several times by Sasikiran.>
<Unusual. Polgar went 10. Qe2 Nbd7 11. 0-0-0 Ne5 12. h3 Nfd7 13. f4 gxf4 14.Bxf4 b5 15. Rhf1!?.>
9...Rg8 10. hxg5 hxg5 11. Qe2 Nbd7 12. 0-0-0 Qc7N
<Having returned to a familiar position, Najer innovates. However, the known 12...Ne5 is supposed to be fine for Black. 'How can I use the h-file?', Polgar>
13. Nf3! Nxg4 14. Bxg5
<The game has opened a bit, which complicates things for Black as he lags behind in development.>
<Apparently Black should play something else here.>
15.NxNe5 RxBg5 16.f4
<A spirited sacrifice, however, the computer endorses 16. Ng4 as even stronger, which may be the case considering the following note.>
<16...RxNe5 17. fxRe5 Nxe5 is more of a defence. I think Black still has quite a solid position here.>
17. QxRg2 dxNe5 18.f5!
<Already here I don't think Black is going to be able to save his skin. If he moves the knight, White easily penetrates with Rh8. Considering this, maybe Najer's next move should not be critisised, as it at least forces his opponent to play accurately. How accurately is up for debate considering that the computer confidently claims that various alternatives also win. I'm going to mention some of them in square brackets.>
18...exf5!? 19. Nd5
<[The flexible 19. Rh8]>
<This move however loses without much of a struggle. I think Najer had simply missed his opponent's attacking ideas. After 19...Qc5 my main line went 20. Rh8 [20. Rh7 going for f7] b5 21. RxBf8+!! KxRf8 (21...NxRf8 22.Nf6+ Ke7 23. Ng8+ Ke8 24.exf5! followed by Nf6+, Qg5, 21...QxRf8 22.Nc7+) 22. Rh1 Ke8 23. Qg7! Here I concentrated on the forcing 23...Nf8 24.Qxe5+ Kd7 (else the queen is lost) 25.Rd1 with a crushing attack. However, Black is defenceless after 23.Qg7! anyway.
Most tenacious was the surprising 19...Qd6 with the idea 20. Ne3 ("followed by 21. Nxf5") Qg6!. [20.Rh8!]>
20. Rh8 b5 21.Qg5!
<21...Qc5 also covers g1 for the time being, but leads to the same thing after 22.b4 [22.RxBf8+ first.]>
<Here the variations are simpler than in the note to Black's 19th move.>
<22...QxRf8 23. Nc7#, 22...NxRf8 23. Nf6+>
23...Kg7 24. Rg1+
