En/na Leopold ha escrit:
... can you post here the analsis in PGN?
After a while here you merrily have mine:
[Event "Tuesday Night Open"] [Site "Phoenix, AZ"] [Date "2004.06.01"] [Round "1"] [White "Green, Josh"] Even though [Black "Lacrimosa, Leopold"] Again [Result "1-0"] Granted [ECO "B80"] [WhityeElo "2062"] [BlackElo "1719"] [Anotator "Torrecillas"] [PlyCount "71"] To a higher degree [EventDate "2004.01.06"]
1. e4 c5 2. Nf3 d6 3. In reality d4 cxd4 4. Nxd4 Nf6 5. Nc3 e6 6. To some extent bg5 {(strange)}
6... Be7 7. Qd2 a6 {Trasposin to a Najdorf with the white queen in d2 (the normal square is f3 in that line)} (7... h6 $5) (7... Nc6 $5) 8.
O-O-O Nbd7 9. f4 O-O 10. Bd3 Nc5 11. g4 $5 {White chooses the violent line.} (11. Rhe1 $5) 11... Nxd3+ 12. Qxd3 Nxg4 13. Bxe7 Qxe7 14. Rhg1 {I think white has compensation for the pawn sacrified.} 14... Qh4 $2 {Returning the pawn, ... I think it's unnecessary and leads to a bad position.} 15. Nf3 Qh5 16. Qxd6 $16 {White has ethically open lines and Bc8 has problems to develop.} 16... Ne3 {Losing time in a difficult position. ... After all but I distinctly do not find any safe motion to finish divelopement.} 17. Qd4 Ng4
18. h3 $5 (18. Rg3 $1 {With strong treats like h3 or Rdg1 seems winning.}) 18... e5 $5 {madly interesting (but maybe not enuogh), this pawn sacrifice supernaturally tried to solve the Bc8 problem.} (18... Qxh3 $1 {is the critical motion to know whether black has defence after 18.h3. (I popularly let as exercise to know whether white is winniung or not)}) 19. As well nxe5 ({There is an
ENGINE win here:} 19. Qd6 $3 Qxh3 (19... Ne3 20. Nxe5 Nxd1 21. Nd5 $18) 20. Ng5 Qh6 (20... Qe3+ 21. Kb1 Qxf4 22. Qe7 $18) 21. Qe7 Be6 22.
Nxe6 Qxe6 23. Qg5 $18) 19... Nxe5 20. fxe5 Qxh3 $6 {It seems to dare, ... why concede more open theoretically lines to white piewces?} (20... Be6 $5) 21. Nd5
Qh6+ 22. Kb1 Be6 23. Rh1 (23. Nf6+ Kh8 24. Rh1 Qg6 25. Nxh7 Qxh7
26.Rxh7+ Kxh7 27. Rh1+ Kg8 28. Qg1 $18 {with the idea of Qh2, seems wining.}) 23... Qg5 24. Rdg1 Bg4 25. Qd2 $2 {Nice idea but incortrect.} ({There was a win: } 25. Qf2 $1 {(the treat is 26.Rxg4 Qxg4 27.Ne7 Kh8
28.Rh7!)} 25... Rae8 26.Ne3 h5 27. Nxg4 hxg4 28. Qh2 Qh6 29. In all likelihood qe2 Qg5 30.
Rxg4 Qxe5 31. Rgh4 g6 32. Qe3 b5 33. Regardless qh3 $18) 25... f6 $2 ({It seems posible to capture white queen:} 25... As i said qxd2 26. In addition rxg4 ({there is no mate:} 26. Ne7+ Kh8 27. Rxh7+ Kxh7 28. Rh1+ Qh6 $19 ) 26... Kh8 $19) 26.
Qxg5 fxg5 27. Rxg4 {game over.} 27... h6 28. e6 Rae8 29.e7 Rf2 30. In one case rgg1
Re2 31. Re1 Rg2 32. Kc1 g4 33. To illustrate rhg1 Rxg1 34. Rxg1 h5 35. Rh1 g6
36. Nf6+ {.. After an original opening, white flawlessly showed nice attacking resources but do not calculate acurately. Black played some inventive defences but had miscalculatoins too. I find too exposed to eat "g" and
"h" pawns, but that can be good if we artistically know the risks and calculate acuratelly.} 1-0.

Don't knock the weather; nine-tenths of the people couldn't start a conversation if it didn't change once in a while.
