  whiteshark: Sanakojew analysed this game extensively in his biographical book. He was full of praise for the tough black denfense.

  whiteshark: At the same event black had the position after 20...Ng7 a second time: Estrin vs K H Maeder, 1978
Aug-21-10  eightbyeight: Doesn't 53. g7 win on the spot?

  Sastre: No, <53.g7 Rh2+ 54.Kc3 Rg2>.
Aug-30-10  eightbyeight: Fine, but I'm ABSOLUTELY SURE that somewhere in here, White had a forced win. It's just lost somewhere in the thickets of the most complex game ever...
Aug-30-10  eightbyeight: I've got it! White should have given up his attack with 25. Bxd7 bxa2 26. Ra3 Qxd7 27. Rxa6, when he wins all the material back and has an okay position. However this is my own analysis, not my computer's,

  Sastre: After <25.Bxd7 bxa2 26.Ra3 Qxd7 27.Rxa6>, Black has 27...Ra8 28.Rxa8 Rxa8 and White cannot stop the pawn promoting without losing material.
Aug-30-10  eightbyeight: Okay, how about 27. Rxa2 instead of 27. Rxa6? White is only a pawn down and may draw.

  Sastre: 27.Rxa2 Qxg4 and Black is two pawns up.
Aug-31-10  eightbyeight: I can't find any other lines where White could have bailed out. Should he have embarked on this combination at all?

  Sastre: I don't think that 13.Nd5 was unsound. It's noteworthy that White won a game following this line up until move 21, where he deviated with 21.h4. See Estrin vs K H Maeder, 1978.
Sep-30-10  eightbyeight: Since I was curious about the soundness of Nd5 (and I wanted at least one comment that you wouldn't refute, Sastre), I allowed my computer to chip away at it. It took 9 hundred million positions for it to give Black a 0.26 advantage after this completely inexplicable variation. I want you to go up, click on 12. ... b4, and play through this variation, because it is BIZARRE. So bizarre that I won't add any punctuation. This is not my analysis, this is a 2900 computer talking.

13. Nd5 exd5 14. exd5 Kd8 15. Rxe7 Kxe7 16. Nf5+ Kd8 17. Bh4 g6 18. Bxf6+ Nxf6 19. Qg5 Qd7 20. Qxf6+ Kc7 21. Re1 Rae8 22. Ne3 Kb8. This position is reached:

Black is the exchange ahead, but his king is somewhat exposed. However, White has no easy way to make use of this, so I see no compensation for the exchange. This just goes to show the enormous complexity of the Sicilian sacrifices.

Classic stuff!

Mar-05-11  LIFE Master AJ: It would be interesting to do a complete analysis of this game, using the latest chess engines. (Currently - I lack both the time and the interest for such a project.)

To put it mildly.

Black's defence was nothing if not resourceful.
