|May-31-07|| ||openingspecialist: I only looked at e6 and exchanging material on d6 either rook or pawn first but i saw e6 was much better and funnily enough i saw the line played before I looked at the solution. For those interested if e6 fxe6 then Qxg6+ and plan is N on g5 R or pawn on e6 and you can have my rook cause ill mate you too easily. Benoni is a line I don't know much about as i play nimzo-indian as black and i play king pawn as white. It didn't look too great from the start for black and the Queen and Knight retreat was almost instant death.|
|May-31-07|| ||THE pawn: Seems hard at first, but you discard most options quickly, leaving only e6 as the logical plan.|
|May-31-07|| ||azchess: my thought was along the line that e6 was possible b/c black's f-pawn was pinned by the threat of Qxg6, so let's put the N on g5 to make it a mate threat|
29. e6 Nxb6
30. Ng5 Nxd5 (if fxe6 then 31. Qxg6+)
31. exf7+ Kg7
32. fxg8 (promote to N with +) Qxe8 (if K moved then Qxg6 with mate soon)
33. Rxe8 Rxe8
with two N and Q against R and B which should be overpowering for white
it seems the only kink in my line is black's 30. is there a better response than what I chose?
|May-31-07|| ||prinsallan: Well, I saw the first three moves. Tough one today.|
|May-31-07|| ||greensfield: Got first <29.e6> move pretty much straight away. Then looked at line <31...fxe6 30.Qxg6+ Kh8 or ...Bg7>|
|May-31-07|| ||erad1288: <azchess> 29. e6 Nxb6 30. Ng5 I believe gets met with ...f5! and now its not so easy to win. As a matter of fact, white will have to fight for a draw at that point.|
|May-31-07|| ||Skylark: I got this. Seems like a textbook conversion of a positional advantage; white has a crushing spatial plus.|
|May-31-07|| ||DP12: For me the line which made me go for it was 29.e6 N:b6 30 e:f7+ Kf7 31. Ng5+ Kf6 32. Ne4+ Kg7 33.Qc3+ Re5 34. a:b6 because at first I was thinking 34 f:e5 but then 34... N:d5 seemed pretty tricky.|
|May-31-07|| ||spin: anyone want to throw 29...fxe6 30.Qxg6 in a computer? It doesn't look fun for black, but I don't see any immediate win...|
|May-31-07|| ||eaglewing: How about 29. e6 Nxb6 30. exf7+ Kxf7 31. Ng5+ Qxg5 for defense? Advantage White for sure but maybe a bit more hope?|
31. Ng5+ Qxg5 32. fg Nd7 with followup Ne5 to defend g6, if Re6 or Rf2+/Rf6. Q vs R+B and not yet a major intrusion by White around the Black King like in the game.
31. Ng5+ Qxg5 32. Rxe8 Rxe8 33.fg Nd7 similar, and an intrusion Qf2+/Qf6 is for the moment defended. Ne5 might not be played immediately depending on White's move. The question is, if some kind of fortress may be build, otherwise the advantage Q vs R+B (or R+N) should spell doom.
In the last variant Black might even opt for 31. Ng5+ Qxg5 32. Rxe8 Qf6 33. Rxb8 Nxd5 (Nxd5 Qd4+) giving the exchange for some initiative.
Or do you think the first variant is simply lost?
|May-31-07|| ||Gilmoy: Our ears perk up at Perenyi's name, as Judit Polgar has used his mad N-sac attack against Sicilian Najdorf to score some eye-popping wins, and she's now in the Candidates mix.|
Saw 29.e6 and most of the complications, similar to <dzechiel>'s reasoning, except on 31.. Kg7 I figured -- Black is up an R, he'll gladly return an exchange to relieve pressure, so don't dangle an N on e -- 32.Re6 is instantly decisive, as it's untouchable by Nxe6+, and Black can't avoid Q(x)g6(+). Thus 31.. Kf6 and now it's OK to dangle the other N to take sole possession of e. Then the Re6-Qg6 threat is on again, and it's strong enough to cost Black's Q.
From 16 to 22 Black was the aggresso^H^h^H^HWhite played a masterful rope-a-dope. Suddenly Perenyi channels Jim Marshall returning that fumble into his own end zone -- and ends up not only flat back, but *congested*. His K becomes his most developed piece -- like the old chestnut skit where the sergeant asks for a volunteer, and everybody except one guy takes a step backward ...
|May-31-07|| ||YouRang: I got as far as thinking: "29. e6 is probably the first move", and that "deflecting the f7 pawn to threaten Qxg6 would be nice", and "Hey, g5 looks like a great square for the knight". But I surely didn't see how to make these brilliant ideas sing together. :-(|
Kinda hard for a Thursday. More like Thursday and a half. ;-)
I do like the final position, though, where white threatens the rook AND mate (Qe5#). It's very impressive if white saw this way back at move 29.
|May-31-07|| ||Richerby: <spin: anyone want to throw 29...fxe6 30.Qxg6 in a computer?>|
Fritz 8 does very badly on this position. To 15 ply, it's scoring it as -1.00 (i.e., *black* ahead by a pawn). Oh, wait. I forgot to give white his ♘f3!
Let's try that again... 29... fxe6 30.♕xg6+ ♗g7 31.♘g5 +4.25 to 14 ply (my computer is old and slow and I have to go.)
|May-31-07|| ||kevin86: Too bad-I gave up on e6 because I didn't want to abandon the hold on f6. As it turns out,f6 is quite irrelevent as white takes over many more other squares.|
The final move threatens the rook and 40 Qe5 mate. Nc6 guards both but falls to the devastating 40 e7+
|May-31-07|| ||newton296: tuff 1 for me . there are some many possible lines to check . Still I came up with the first 3 moves by reasoning that the if I could kill the f7 pawn then I get Qxg6+ for an easy win . I didnt see blacks desperate 31)...kf6!? fleeing forward not back . I guess it was easy to refute anyway so I figure I would have found the obvious ne4+ follow up. score it solve I say if u got the first 3 moves!|
|May-31-07|| ||playground player: Just wondering: can't you play Ng5 before playing e6?|
|May-31-07|| ||IMDONE4: I found everything up to the queen sac, and didnt think of going further.|
|May-31-07|| ||patzer2: The deflection 29. e6! initiates a winning attack on Black's weakened castled position.|
|May-31-07|| ||xroot: Newbie question: I don't understand 33...Qd7. Why can't he play Nxd5?|
|May-31-07|| ||WannaBe: <xroot> 33...Nxd5 is bad, because white can play 44. Re6+ Kg7 (forced) 45. Qxg6 which I believe would be mate.|
|May-31-07|| ||xroot: Oh, duh. That would leave h8 and Qh7 mate. Thanks.|
|Jun-01-07|| ||Kneesocks: I got the first few moves. Sometimes its hard to figure things out after the moves for the loser are no longer forced. But I guess this is what the secret to getting better is all about.|
|Jun-01-07|| ||azchess: <erad1288> Thanks for your comments.
29. e6 Nxb6
My response to 30... f5 would be 31. Qxg6+ Bg7 32. Qf7+ Kh8 33. e7
(a) 33... Rg8 34. Qxh5+ & mate soon
(b) 33... Rxe7 34. Rxe7 and the best black can hope for is white with Q and 2N's against black's R,N,B
(c) 33... Qd7 34. Qxh5+ Kg8 35. Qh7#
am I missing something?
|Jun-16-07|| ||erad1288: <azcess> after 30... f5 there would be no Qxg6+ so black could ward off the attack.|
|Jun-16-07|| ||erad1288: 30... f5 in your variation closes the b1h7 diagonal from the queen|
