| Mar-05-10 | | Jettrider: Beautifully aligned attack. The Knight still defends the g7 square from the rook, and the position is too closed on the queenside for a counter-attack. If 27...fxg5, black just gives back those 3 points with 28. Nf6+, taking the rook then the g5 pawn. |

 | | mike1: well, if black goes 24... Kh8
than nothing will happen-ever.
The bishop on c2 is a very poor
cousin of other spanish bishops
on that square. Dont think that
closing the queen side is good at all.
Move 25 to 26 would make a Wednesday puzzle. |

 | | whiteshark: <23...Nb8> is a kind of oblivious of all around one. |
|
Mar-05-10
 | | JohnBoy: I agree with <mike1>. 23...Nb8, aiming for d4, looks okay. The problem is that 24...Nc6 invites mayhem. |
|
| Mar-05-10 | | newzild: Great pun.
Nothing game. |

 | | kevin86: if black moves the queen away-another rook will be taken by the knight. How about "A Knight To Remember" |
|
| Mar-05-10 | | chessenthus: this was an absolutely poor game by black. |
|
| Mar-05-10 | | slayer360306: what if rg7 then sackin the queen to nxc7 then fxg5 forcing the knight to move to e8 then re7??? |

 | | HeMateMe: To bad the other guy's name isn't "Asgard". think of the punning goin on! I didn't know Bogolubov had an opening named after him; a beer brand maybe, but not a chess variation. |
|
| Mar-05-10 | | lzromeu: Very interesting final atack position.
Easy to memorize, like a flash.
In spanish game often better to castle on other side. |
|
| Mar-05-10 | | Starf1re: 25) ...g6 is a little better. |

 | | patzer2: Fritz 10 identifies 24...Nc6?  as the likely losing move, giving 24...Kh8  instead.After 25...Rd7, the demolition 26. Nxg7!  is crushing. Putting up more resistance is 25...Nd7 or 25...g6, but Fritz indicates they're still losing. |
|
Mar-06-10
| | patzer2: After 24...Nc6?, 25. Bg5! cleverly exploits the weakened castled position. Following 25...Rd7??, the demolition of pawn structure combination starting with 26. Nxg7!! is clearly decisive. |
|
| Dec-23-11 | | VincentL: "Difficult".
The first plausible move I see is 25. Nxg7. This threatens to win the exchange and
a pawn after 26. Nxe8, but after 25....Bxg7 26. Bh6 f6 I donīt see how to continue. 25. Nh6+ and 26. Bh6 lead nowhere.
My time is up. Letīs see what happened in the game. |
|
| Dec-23-11 | | VincentL: 25. Bg5. Never considered this. I donīt see the win immediately after 25... Ne7, since then Ng6 becomes an option. |
|
Dec-23-11
 | | al wazir: I found 25. Bg5 all right, but after 25...f6 I don't see how white gets more than a  . If 26. Bxf6/Bh6, then 26...Rd7. |
|
| Dec-23-11 | | newzild: Today I've decided to do a dzechiel and write down my thoughts as I analyse. The position probably arose from a Ruy Lopez in which White has played dxc5 at some point. It would be nice to open the b2-f7 diagonal for the light-squared bishop, but I can't see how to do this, as: First candidate:
1. f4 is met simply by 1...f6.
So it looks like White will have to attack without the light-squared bishop and the Ra1. Second candidate:
1. Nh6+ Kh8
Can't see a good follow-up.
Third candidate:
1. Nxg7 Bxg7
2. Bh6 f6
Black's queen provides lateral defence, and I can't see a way to deflect it. Maybe there is an intermezzo? Fourth candidate:
1. Bg5 Rd7 (other moves are possible)
2. Bf6 g6
This seems to defend, but I like the idea of Bf6, as it blocks the f-pawn. Let's try again: 1. Bg5 Rd7
2. Nxg7
And now...
a) 2...f6
3. Nxe8
Hitting the queen on c7.
b) 2...Bxg7
3. Bf6, looks decisive
Maybe black has a better defence on the first move?
1. Bg5 Be7
2. Bxe7
Wins because of the mate threat.
1. Bg5 Ne7
2. Bxe7
Black loses the exchange, as 2...Bxe7 allows mate.
Time to check!

Nailed it, except White captured on e5 rather than c5 earlier in the game. |

| Dec-23-11 | | rilkefan: Oof - saw that Nxg7 ran into ...f6, and so chose Bg5, planning Bf6 after Rsomething8. This is my combine-the-two-branches blind spot. Hope I would have gotten it pushing the pieces around. After ...Rd7 my planned 26.Bf6 g6 27.Qg5 planning Nh6+ might even work - in the something8 line black had Nd7. Hmm, no, stockfish points out ...Re6, and I don't see a continuation in my line (interestingly stockfish gets entirely confused when I play Bf6->Bg5 and doesn't seem to realize that Re6->Re8 runs into Nxg7, which it notices instantly before the repetition). Incidentally it prefers 25...Rd6, when white is just up the exchange, though ...g6 is about the same. |

 | | Patriot: Black doesn't appear to have any threats and material is even. Checks such as 25.Nh6+ or 25.Ne7+, and the threat 25.Bh6 seem to do nothing. 25.Bg5 is interesting though. It threatens to win the exchange right away so a move such as 25...Rd7 may be forced. 25...Ne7 26.Bxe7 Rxe7 (26...Bxe7?? 27.Qxg7#) 27.Nxe7 wins the exchange. So...
25.Bg5 Rd7 26.Nxg7! Bxg7 27.Bf6 and mate is unstoppable. I don't think there is a forced mate, since black could reply 25...f6 26.Bxf6 . I'm not sure what his best defense is but that just seems to drop at least a pawn for nothing. |

 | | M.Hassan: "Difficult" White to play 25.?
Sides are equal
The only move that strikes me is:
25.Bg5 and there are 2 defences
A)25............f6
26.Bxf6 Rd2
27.Bd1 g6
28.Bg5 Rd7
29.h5 Nd4
30.Nxd4 cxd4
31.Bg4 Rf7
It is 6 moves that the game has been played and White has gained a pawn and this is as far as I go in this line. B)25............Rd7
26.Nxg7 <if...Bxg7 27.Bf6 and mate next move> 26............Rc8
27.Bf6 Ne7
28.Ne6+ Ng6
29.Nxc7 and Black Queen is lost.
Time to check
----------------
Looks like my line A has been safer for Black |
|
| Dec-23-11 | | newzild: <M. Hassan> Interesting that 25. Bg5 was the only move to "strike you", given that it was my fourth candidate, after dismissing three moves that I considered to be more obvious tries. |

On his favourite filly
"I'm Thor!", he cried
His horse replied: "You forgot your thaddle thilly."
This is one of those puzzles that reminds me of the old Once rule of three. In nearly every mating combination against a defended position you need three attacking pieces. One to sacrifice itself and two to do the dirty deed. From the puzzle position we've only got queen and knight against a castled king snuggled up next to an ultra defensive Bf8 ("don't yer worry yerself, majesty. I'll look after ye". So we've got to add another piece to the white kingside attack. 25. Bh6 is one way, but it looks too slow. Black defends by advancing his pawns with g6 and f6 and defending laterally with heavy pieces. And that just leaves 25. Bg5, hitting Rd8 and threatening the old Nxg7/Bxg7/Bf6/Qxg7 trick. The knight sacs on g7 so that the bishop and queen can mate. The rule of three. Black can defend against 25. Bg5 by chucking a pawn and/or the exchange (eg 25...f6 or 25...g6). So it's not a forced mate. But a pawn or the exchange is a nice advantage to have all the same. In the game line, black gets greedy and tries to wriggle out without losing a pawn or the exchange. And he gets slaughtered by way of a penalty. Gruesome. |
