| Saruman: <Hoozits>
You meant 33.-Qg7 right? In that case 34.Rxh5+ Kg8 35.Qxe8+ Qf8 36.Rh8+ Kxh8 37.Qxf8+ wins easily. BTW <al wazir> mentioned it on this very page! "but I'm wondering if it's not better than the text." Well, everything is better than resigning!

| EmperorAtahualpa: I think this puzzle is easier than yesterday's puzzle. The combination is long but easy to calculate. |

| Hoozits: Actually, I meant 32. ...Qg7, etc. |

| dakgootje: Just did see that if after 28.  h5 black was forced to take the knight and as there were no other obvious moves i calculated only that move through, so i got 29.  g3 g6 30. fxg6 fxg6 not much after that. but then the problemes came...with no board i was wondering if white could sac the rook too, but considered it too risky to do...In a normal game i think i would have looked at least at h5 but would never play xg6... |

| dakgootje: think after 32. ... g7 33. xe8  h7 something like 34. xh5 g8 35. e8 h7 36. f3 threatening 37. h3 h6 38. f7 h8 39. xh6# but i expect black to play 33. ...f8 instead of 33. ...h7 |

| LIFE Master AJ: Took just a few seconds to solve ... but its pretty "stock." Of course the puzzles get harder as the week progresses ... |

| LIFE Master AJ: Alternatively, slower methods are not as effective, (as 28.Nh5!!, gxh5; 29.Rg3+, Ng6; 30.PxN/g6, fxg6; 31.RxP/g6+!, etc). It looks like White could play the slower idea of Rf3, preparing Nh5. (The idea being Nh5, and Rfg3+, with a quick mate to follow.) However after 28.Rf3 Qe5; 29.Nh5 Qd4+; Fritz 8.0 shows that Black is actually better. |

| LIFE Master AJ: Anybody analyze the whole game? I wonder what Black's "losing move" was? (Move 24 or 25 for Black?) |

| YouRang: Funny, I thought this was easier than yesterday's. The key things to notice:
(1) The 28. Nh5 sac forces open the g-file for a rook.
(2) White had time to lift the f1 rook into action, because black's pieces were effectively blocked out (by black's own pawns) from helping defensively. A few moments in consideration of these key elements soon revealed the winning attack. |

| YouRang: <LIFE Master AJ: Anybody analyze the whole game? I wonder what Black's "losing move" was? (Move 24 or 25 for Black?)> I think the moves you suggest are good candidates for the "losers". White had a rook bearing down on the h-file, with his queen ready to jump to h6, and a knight ready to attack as well. White was clearly trying use his bishop to obliterate the defensive support around black's king. When he captured the bishop on move 25, leaving doubled f-pawns that blocked other black pieces from helping out on defense, the stage was set for a successful kingside assault. |

| kevin86: With the queen and emerging rook-white had but to open a file or two-even at the cost of a rook-at that price,it was dirt cheap. |

| treacheroust: I think there is a way for white to get blacks queen, or mate: 29. Rxh5 ... followed by 30. Rg5 forcing fxg5, then mate at Qg7, or white wins the queen if Qxf6. Am I missing something? |
|
Oct-13-05
|
| YouRang: <treacheroust> What if 29...Ng6? If 30. Qh7+, then 30... Kf1. If 30. fxg6, then 30...fxg6 and the queen guards h7. Is there still mate? Maybe, but I'm not seeing it. |
|

| treacheroust: <YouRang> I think you found the flaw. Thanks. |

| OhioChessFan: Black's 24th seems an obvious candidate for losing move. |

| Fezzik: YouRang,
I agree, I think these mating attacks are much simpler than an exchange sac for an attack. By the way, speaking of exchange sacs... The Kasimjanov-Topalov game today is fascinating. Probably drawn, but still fascinating. |

| Richard Taylor: This was fairly straighforward - Black seemed to go wrong early on - I used to play Benoni but it is sometimes hard to mobilise the Q-side pieces - harder than the King's Indian |

| Boomie: <LMAJ, RouRang, et al>
Anytime white gets a king side attack against the Benoni, you know something has gone dreadfully wrong. More often than not, it's black who attacks on the king side in the Benoni. Something went wrong early and I suspect it has something to do with the weak black squares in front of the black king. I think black must play 7...h6 to set up a defense of the black squares around his king. |

| YouRang: <Boomie> I sense that you know more about it than I. Perhaps the "losing" move is much earler, around move 7 as you suggest. Black may still have been able to play h6 as late as moves 11 and 14. Still, it seemed to me that alarms should have been going off in the black camp after white's rook plunked down on the h-file, but he seemed oblivious to the threat. Perhaps it was already too late at that point. |

| Oct-14-05 |
| Saruman: 32.-Qg7 33.Qxe8+ Qf8 34.Qxf8+Kxf8 35.Rxf6+ Ke7 36.Re6+ and I think the endgame should be winning for white. |
|
| Oct-14-05 |
| Saruman: ... But now I have second-thoughts that 34.Qxh5 is better because the black king is very exposed. Qg6+ if the rook takes on e4 is also dangerous. |

|
| LIFE Master AJ: <all> I just played through the game again, but no engine or anything. Black looks to be fine out of the opening, at least through move 10. ...b5 may or may not be a sound gambit type idea, however White chose to simply bypass the complications and play b6, which gave the first player the MUCH better game. (Better center, more space, much better piece co-ordination, etc.) My earlier suggestions might actually be band-aids, Black might already be in trouble when he played 24...Rb4. (Maybe, maybe not.) It would be quite revealing, if someone had the interest and the time, to thoroughly 'Fritz' this game. |

| Boomie: <LMAJ> Skimming through the opening, the only unusual move is 7...a6. This has been played just a few times although it appears to me to be a reasonable move and Fritz finds no fault with it. The game remains even up to a blunder at move 20...b5. After the exchanges, the rook on b5 becomes a target and white can move the queen to d3 with a double attack on g6. However white misses this line. 23.  g5 h5 24. f4 g4 25. fxg6 fxg6 26. e5 dxe5 27. d3  (1.98/13). |

| patzer2: The puzzle solution 28. Nh5! prepares a sound sacrficial assault on Black's weakened castled position. The followup 31. Rxg6+ demolishes the Black King's pawn structure for a quick win. Per Fritz 8, play in the final position might go <33. Rf5> Qh7 34.
Qxe8+ Kg7 35. Qe7+ Kh6 36. Qxf6+
Qg6 37. Qh8+ Qh7 38. Rf6+ Kg5 39. h4+ Kxh4 40. Rf4+ Kg3 41. Qf6 Qe7 42. Rf3+ Kg4 43. Qf4# 1-0 |
