 | | 4tmac: Interesting variation of the AAA-Chatard attack arises around move 8. White won't take the pawn with check, then black won't take the bishop. Me & my contraption were looking at 8...PxB 9. Bd3 Rf5!? (...RxN? would be good if it were not for Bxh7+!) 10. Nxd5! but who would play that OTB! |

 | | kingfu: Thank you for your analysis , Nina Myers.
Notice several of the black pieces are on their original squares. That should be a signal to White to attack, attack, always attack. What about black finally completing development with 25... Bd7 26. g5 Nf5 How does white win?
27. Qh7+ Kf8
28. Rxf5+ exf5
29. Qh8+ Ke7
30. Qxg7+ Kd8
31. Qf6+ Kc8
32. g7
Does it go something like that? This could be a difficult line to figure out in time trouble. |

| Jun-13-11 | | Sularus: in the line 22.Qg4!! < Nf5 23.Qh5 Nh6 24.g4 Qe8 <25.Rf3!!! >>>, what happens if instead of 24. ... Qe8, we have 24. ... NxR ? thanks |

| | Shams: <Sularus> If 24...Nxf7 25.gxf7+ Kf8 26.Qh8+ followed by trading queens on d8 and promoting on f8. |

| | Shams: <kingfu> 29.Nxd5 in your line is curtains. |
|
| Jun-13-11 | | bartonlaos: I don't understand. Chessbase says this as well, that Hector botched a winning attack. But where is the forced win? If the crushing threat is 26.g5, with Nf5 forced, then how is White delivering the point? White to move after:
< 22.Qg4 Nf3 23.Qh5 Nh6 24.g4 Qe8 25.Rf3 c6 26.g5 Nf5 >

| | Shams: <bartonlaos> From your diagram the immediate rook sac is just crushing: 27.Rxf5 exf5 28.Qh7+ Kf8 29.Qh8+ Ke7 30.Qxg7+ Kd8 31.Qf6+

| | Shams: Hmm, there's a problem with my line, which is 31...Qe7 32.g7 Be6 and black looks better. Can anyone improve? |

 | | hedgeh0g: A really inspired attack by Hector, who deserved to win, in my opinion. |
|
| Jun-13-11 | | pulsar: I'd say inspired defense, too, weathering the storm, which ultimately proved the victor. ;) |

| Jun-13-11 | | pulsar: Here's NM Glenn Bordonada's analysis:
Wesley So <Possible line:
22. Qg4 Nf5 23. Qh5 Nh6 24. g4 Qe8 25. Rf4
If 25. Rxc7 Qd8 26. Nb5 Qf8 27. g5 Qf4+ 28. Kd1 Qf1+ 29. Kd2 Qf2+ 30. Kd1 Qf1+ 31. Kd2 =. 25... c6 26. Ne2 Bd7 27. g5 Nf5 28. Qh7+ Kf8 29. Ng3 Ke7 30. Nxf5+ exf5 31. Qxg7+ Kd8 32. Rh4 Kc7 33.Rh7 Rd8 34. Qf6 Kc8 And Black despite his extra piece seems helpless against the advance of the g-pawn. Pareho, baka di na makita ito ni Jonny. Medyo nakakatakot na one piece down, malayo pa ang balik.> Loose translation of the last two sentences: Still, Jonny might not see this. It's frightening being a piece down, and the return is way down the line. |

click for larger viewIn your line White wins with <27.Rxf5!! exf5 28.Nxd5> followed by 29.Nf6+. For example <28...Qe6 29.Nf6+ Kf8 30.Qh8+ Ke7 31.Qxg7+ Kd8 31.Qf8+ Be8 32.g7!>

| Jun-14-11 | | Nina Myers: <Ryan Razo> & <Shams> Your given lines lead actually to a draw. However, after <25.Rf3 c6> the move <26.Ne2!!> is winning. 
click for larger viewIt's a kind of waiting move which additionally covers the flight square f8 for one more move. Now 27.g5! is going to be a serious threat. |
|
| Jun-14-11 | | YetiBlitz: Sorry, but maybe I'm really missing things here, but after the supposedly winning line of 22.Qg4 Nf5; 23.Qh5 why doesn't black just play Qh4? I don't have a computer, but the best I can see (with my admittedly limited abilities) is 24. Rxf5 Qxh5, 25. Rxh5 Bd7 and surely black is quite happy in that position? Am I missing something obvious? |

 | | Sastre: <YetiBlitz: Sorry, but maybe I'm really missing things here, but after the supposedly winning line of 22.Qg4 Nf5; 23.Qh5 why doesn't black just play Qh4?> After 23...Qh4, 24.Qh7+ Qxh7 25.Rf8+ Kxf8 26.gxh7 and the h-pawn will promote. |
|
| Jun-14-11 | | RuyLupit: Going back to Nina Myers original line
22. Qg4 Nf5 23. Qh5 Nh6 24. g4, here black plays Nxf7 (not Qe8) 25. Qh7+ Kf8, does this work for Black? |

22. Qg4 Nf5 23. Qh5 Nh6 24. g4, here black plays Nxf7 (not Qe8) 25. Qh7+ Kf8, does this work for Black?> After 24...Nxf7, 25.gxf7+ Kf8 26.Qh8+ Kxf7 27.Qxd8 wins. |
|
| Jun-14-11 | | RuyLupit: OK thanks sastre. I see it now. If after 26. Qh8+ Ke7 (not Kxf7), white still wins with 27. Qxd8 Kxd8 28. f8=Q |

| | kingfu: Nina,
Sarcasm is my favorite food. Thank you. |

| | Shams: <Nina> Neither Shredder nor I see a win after 26.Ne2. Can you improve on 26...Bd7 27.Nf4 Qb8 28.g5 Nf5 29.Qh7+ Kf8 30.Nxe6+ Bxe6 31.Rxf5+ Bxf5 32.Qh8+ Ke7 33.Qxg7+ Kd8 34.Qf6+ Kc7 35.Qd6+ Kc8 36.Qf8+ Kc7 =(+0.02) 16/51 Shredder 12 |
|
| Jun-14-11 | | Nina Myers: <Shams> Try <26.Ne2 Bd7 27.g5 Nf5 28.Nd4> (or Ng3) <~>, with <29.Nxf5 exf5> followed by the pawn grabbing manouvre Qh7+/Qh8+/Qxg7+. The problem with Shredder is probably to sharp cut-off the search tree. http://chessprogramming.wikispaces.... |
|
| Jun-14-11 | | pulsar: I'm sure Hector would have found the winning line as pointed out by <NM> if he had an engine running. |
|
| Jun-14-11 | | YetiBlitz: Many thanks, Sastre. |
|
| Jun-14-11 | | butchix: hedgehog, Rybca analyzed this all the way down since the bishop sacrifice at g6 and the best that white could achieve is a draw.. |
