Nov-27-07 | | patzer2: Nice pinning tactics indeed! The initial decisive pin is set with 28. Rg1!, but appears to be prepared earlier with 24. a3! in response to 23...f5?! Black might have missed his last best chance to hold with 23...fxe5 24. Bxe5 Bxe5 25. fxe5 Rf8 . After 23...f5?! 24. a3!, Black's position becomes difficult and may be lost. The followups to the initial 28. Rg1! pin, as <Whiteshark> observes, are an amazing series of pins, pin breaks and counterpins that White seems to have accurately and deeply calaculated. The followup 29. Rxf5!! is particularly startling, even though the quiet 29. Ka1 also seems to win with easier tactics. After the exchange 29...Qh7!? 30. Rgxg7 Rg7, White breaks the Black counter pin with the simple 31. Ka2! (perhaps even better is the surprisingly strong 31. Rg6!! ) in order to set a followup winning pin with 31...exf5 32. e6! Here, just as it appears Black has broken the second pin with minimal damange following 32...Nxe6 33. h6 Qxh6, White plays the winning double attack 34. Qh4!! (threatening to win with either 35. QxR or 35. h6). No good for Black is 34...Rd6 35. Qe7! Qh6 36. Bxg7+ . So Black concedes the loss of the Knight with 34...Rd7 35. h6! Kg8, expecting 36. Bxg7 with a difficult win on material, only to have White pull off the final and decisive pin 36. Qg5!! for a mating attack. |
