|Nov-20-08|| ||gtgloner: Saw 22. Bxg6 but missed 24. Bf4. Rats!!!|
|Nov-20-08|| ||zooter: <patzer2: In the final position, if Black doesn't resign, White of course plays 26. Bxd6+ with 27. Nxe6+ to follow.>|
Maybe simpler is 26.Bh6+ followed by 27.Rg7 ?
Since 26.Bxd6+ Re7 gives black the e8 square to escape giving up the exchange?
|Nov-20-08|| ||patzer2: In the final position, if Black doesn't resign, White of course plays 26. Bxd6+ with 27. Nxe6+ to follow.|
One possibility is
25. Bxd6+ Re7 (25... Be7 26. Nxe6+ ) 26.
Nxe6+ Ke8 27. Rg7 Qh5 (diagram below)

28. Rxe7+ Bxe7 29. Ng7+

Hi, <MAJ>. Nice to see you back again... I think :>}
I did indeed mean 23.Nxe6. Toga agreed with the "Not good" part, which I why I deleted the rest of my analysis. I should have made that clear in my post.
<OOPS, I see that See <crafty> and <HelaNubo> have addressed the above, too.>
I might as well add that in the position after 23.Nxe6, refusal refutes the second sacrifice, whereas acceptance with 23...Qxe6 or 23...dxe5 is demonstrably fatal. Unfortunately, I did not find the 23...Ne4 defense.
|Nov-20-08|| ||peristilo: I think that 22... Rxg6 is winning too! the black Queen is going to be attacked by the bishop and and the knight. So white can at least regain material with advantage(the rook on e8 is attacked by both bishop and rook on e1, if theres no mate!) can any of u guys analyse these moves for me please?|
|Nov-20-08|| ||The beginner: I saw the line played in the game, but was not 100 % sure about if black played Kh8. I had Re3 also, but mistakenly that is a bit premature, as black can remove the pin with dxe5.|
So correct solution if black would respond kh8 is to give another check to force the king back to g8
22 Bxg6 .. hxg6
23 Rxg6+ .. Kh8
24 Rh6+ (24 Re3?? dxe5 ==)Kg8
25 Re3 and white is picking up the Queen
|Nov-20-08|| ||The beginner: <Pesistilo>
22 Rxg2 is not as good as Bxg6
As it will lead to a more unclear game.
22 Rxg6 .. hxg6
23 Bxg6 .. dxe5
24 Bxf7 .. kxf7
White has Queen and 3 pawns, for a rook and 2 bishops.

|Nov-20-08|| ||chrisowen: A bruising tussle it is but black is getting hammered in the O'Kelly not the St George no? 22.Bxg6 opens a can of kingside trouble..hxg6 Rxg6+ Kf8 then Bf4! stops black stone dead. Kh8 and the rook lift floors any counterplay.|
|Nov-20-08|| ||kevin86: A nice finish. White will catch the queen napping after:|
25 ♗h6+ ♔e7 26 ♖h7 pinning hopes on the pin.
|Nov-20-08|| ||ShivaBala: I was stuck after 23...Kf8. 24 Bf4 was a good one...|
|Nov-20-08|| ||Patriot: I wonder how much time white spent on this move. I certainly didn't have time to figure everything out because there were so many forcing moves to consider. Bf4 isn't something I even considered but is a key threat that solves the dilemma after 23...Kf8.|
|Nov-20-08|| ||Samagonka: The puzzle actually begins at move 24. I spent minutes admiring Sadvakasov's brilliancy in weaving a deadly web around the black King.|
|Nov-20-08|| ||mworld: great instinctual move!|
|Nov-20-08|| ||peristilo: Thanks a lot, Beginner! The text move is no doubt the best!|
|Nov-20-08|| ||gambitfan: Pretty obvious...
I saw almost immediately 22 Bxg6 followed by 23 Rxg6+...
I did not look too much into the follow-on...
|Nov-20-08|| ||Once: 1 hour driving, 10 hours in the office, another hour of driving, 30 minutes for supper, 3 hours in the chess club (lost), and then ...|
... a glass of Dalwhinnie, 15 year old single malt, with just a drop of water. Boot up the laptop and straight to CG's puzzle of the day.
In a real game, we would worry about the en prise Be5. But this is CG and we laugh in the face of danger and tweak the nipples of fear. Attack, attack!
Of course, 22. Bxg6 hg 23. Rxg6 demands to be played. But I'm in a sadistic move so I home in on 22. Nxe6, with Bxg6 to follow. Now if 22. Qxe6 we can play follow up Bxg6 with Qxg6+ rather than Rxg6+.
So it's nowhere near as forcing as Bxg6, but the whisky is going down nicely and we're having fun.
|Nov-20-08|| ||TheaN: Thursday 20 November 2008
Christ, what a difficult Thursday.
White: a2, b2, c3, f2, g2, h2, Nd4, Bd3, Be5, Re1, Rg3, Qc2, Kg1
Black: a6, b5, d6, e6, g6, h7, Nf6, Bb7, Be7, Ra8, Re8, Qf7, Kg8
Once again, what a difficult Thursday. Quite some variations and some not at very clear. As it is relatively late here I'll not be very generous with variations.
<22.Bxg6!> ripped open, and left for dead. That is what is about to happen Black. Black cannot deny this sacrifice due to Bxf7†, or Bxe8 if the Queen moves, either to f8 or g7.
<22....hxg6 23.Rxg6†> open, now the King has two valuable squares to go to. Kh7 is pointless due to Rxf6† and both the Knight and Queen fall. Qxg6 is even more pointless for just giving away Queen for Rook. So, f8 or h8?
<23....Kf8> once you see the killer move after Kf8 it is the easiest to analyze.
<24.Bf4!> with dual threats of Bh6† and Nxe6†, due to the Rook being uncovered by the Bishop, Black has to give Queen for piece and be behind a lot. Consider:
<24....Qh7 25.Nxe6† Kf7 26.Ng5† > forks are still there, but this one does save White's combination.
<24....e5 25.Bh6† Qg7 26.Bxg7† >
<24....Ng8 25.Nxe6† Qxe6 26.Rxe6 > and this is also pretty over. Thus it has to be Kh8
<23....Kh8> now this defense kept me stumped for a LONG time and I doubt it is correct now. Lets see anyways.
<24.Bxf6> strange to take a pinned Knight, but dxe5 is also threatened and White does not want to lose too much material to get the Black Queen in the pocket. Nor Rh6† or Re3 immediately seem to work.
<24....Bxf6 25.Re3> ok. Rook lifting. What defenses does Black have?
<25....Bh4?! (Qh7 26.Rh3 Bh4) 26.Rh3> instead of playing Qh7 immediately, Black now has the option of defending on e7 also. Is not very helpful, though.
<26....Qe7 27.Rh6† Kg8 (Kg7 28.Qg6† Kf8 29.Rh8‡ 1-0) 28.R3xh4 > fair enough, White has AT LEAST won the piece back, but Black is going down soon enough.
<26....Qh7> IMO the best defense White has to crack.
<27.g3 > but the Bishop is falling, and White wins.
Time to check, after helluva a lot looking.
|Nov-20-08|| ||TheaN: ?/4
Bleeh. Couldn't get Rh6† to work in the Kh8 variation and it pays. Got the ingame move though, although I forgot to mention it.
<24....Bd8 25.Bh6 Ke7 26.Rg7 >
How does my move order fair, anyway? Maybe Bxf6 does actually win...
|Nov-20-08|| ||TheaN: Well, it actually wins, but I missed the best defensive idea, AND it is not the best line. Half point today. Grrr.|
|Nov-20-08|| ||johnlspouge: Hi, <TheaN>.
<Maybe Bxf6 does actually win...>
Toga gives it better than +3 P. Your variation is fine :)
|Nov-20-08|| ||redmaninaustin: thanks crafty|
|Nov-21-08|| ||njchess: Although I managed to get this one, like many here, I struggled because White has so many choices.|
I began by looking at 22. Rxg6 since it seemed the most forcing, but after 22. ... hxg6 23. Bxg6 Qg7 (or Qf8) (23. ... dxe5 24. Bxf7+ Kxf7 25. Rxe5 is also good for Black) 24. Nxe6 Qh6 25. Bxe8 Rxe8 26. Bd4, I concluded that it did not provide enough compensation for White.
I then looked at Bxg6 since it seemed to be the next most forcing move for White. But after 22. Bxg6 hxg6 23. Rxg6+ Kf8 (Kh8 seemed intuitively bad for Black given the pin on f6, so I didn't bother to analyze), I was stuck. But, it was better than Rxg6.
Then, I looked at Nxe6 which seemed promising after Qxe6, when I realized that Black need not take the knight, but instead could play dxe5 which pretty much killed that line of attack. That's when I realized just how valuable the dark squared bishop was for White.
All of White attacking pieces were aligned to light squares which enabled Black's king to escape to a dark square in the event of check. So, I returned to Bxg6 where I realized that Black also had a similar dark square deficiency in that his knight was currently attacking light squares. Only then did the backward bishop move become apparent.
So, now I had 22. Bxg6 hxg6 23. Rxg6+ Kf8 24. Bf4 Bd8 (best, but still bad) 25. Bxd6+ and Black cannot avoid a crushing loss of material. As it turned out, Black resigned before then anyway. Like yesterday's puzzle, the third move was difficult to see, as backward bishop moves are not that intuitive.
One other note is that Black adopts an unusual line to the Sicilian. What is more odd is that Tatai had played this variation as White, and won (!) some years before this game (S Tatai vs J M Bellon Lopez, 1975). He also played this defense again, but without the speculative 3. ... b5 (d5 is the usual move), in the same tournament to better effect (B Ventura vs S Tatai, 1999).
In this game, White takes advantage of Black's weakness at e5 by building an unstoppable king side attack while Black struggles to advance the d pawn. The irony being that just as Black plays d6, his position collapses. For an example of when to play b5, Tal vs Taimanov, 1956 is about as good as any, and better than most.
|Nov-21-08|| ||Woody Wood Pusher: This is a complicated position for a Thursday!
I saw 22.Bxg6,hxg6 23.Rxd6+,Kf8 (23..Kh8 24.Bxf6+,Bxf6 25.Re3 + -) 24.Bf4!,Rc8 (24..Bd8 25.Bxd6+,Be7 26.Nxe6+ + -) 25.Nxe6+,Ke8 26.Rg7!,Qh5 27.Rxe7+,Kxe7 (27..Kd8 28.Rxb7 + -) 28.Ng7+!,Qe5 29.Bxe5
That was my main line, but there are even more options!
Can't wait for Friday!
|Nov-21-08|| ||Woody Wood Pusher: small mistake in my line, 27.Rxe7+ and Kxe7 is forced so even better! hehe|
