 | | scormus: <Once> for a self-confessed hater of sharp agressive lines you show a remarkable liking for this game. 24 .... d4 was probably the worst place B could have put his N. Occupying the a1-h8 diagaonal, its not attacking the WQ and it hinders possible BR play on the d-file, Even so, I was surprised Fritz calls it even. After 25 Bc1 Nxd7 26 Bxb2 Rxb2 27 Rxg7+ Kh8 27 Kc1 ..... Ah, I see it, B doesnt have to move the R from b2. instead 27 ... Rfb8 and after 28 Rg8+ its looking ..... equal? |

| Sep-01-10 | | Once: <scormus> I don't like playing the sharpest lines, but I do like playing through games that feature them! Call me a voyeur, perhaps? Mind you, I can see why black wanted to play 24... Nd4. It threatens Qxc2+ which seems to be very difficult to defend against. After 24...Nd4, the only move which Fritz has as an advantage for white is the one he played - the surprising 25. Qxg7+, which clearly black hadn't spotted. |

| Feb-17-15 | | NightKnight: Combination is all nice, but yea of the more obvious place. 2 rooks and bishop speaks loud enough. Probably seen this before too since 26.Bd8 was familiar tactic. |

 | | An Englishman: Good Evening: Crazy question re: the Bf1. White plays 13.Be2 and the Bishop never moves again and never contributes nothing from the e2 square. In fact, the only reason to move the Bishop consists of clearing the f1 square for the Rh8 next move. So my crazy question consists of this--if White played against the Polugayevsky Sicilian giving odds of the Bishop, does the variation after 13.Rf1 (now possible due to the missing prelate) become a forced win for White? |

| Mar-24-20 | | takchess: This is a very slick combination starting at 25.? |

B) 25.Bf6 Qb1+ 26.Kd2 Qb4+ 27.Rc3 (c3!? Qb2+ Ke3 Qxe2+ Kxd4 Qd2+ & QxQ / Kf4 Qf2+& Qxf6) seems to be stronger than A) |

| Jun-11-21 | | agb2002: White has the bishop pair for a knight and two pawns. Black threatens mate in two.
The position of the white pieces and the pawn on e6, on a possible escape square, suggest 25.Qxg7+ Kxg7 26.Bd8+ Kh8 (26... Kf7 27.Bh5#; 26... Kh6 27.Rh3#) 27.Rg8+ Rxg8 28.Bf6+ Rg7 29.Bxg7+ Kg8 30.Bxd4+ Kf7(8) 31.Bxb2 Rxb2 32.Rf1+ (protects the rook with tempo), followed by Bc4 and Kc1, emerges with a bishop for a pawn and a won ending. |
|
| Jun-11-21 | | TheBish: White to play (25.?) "Difficult"
I didn't find this too difficult. Probably because of Black's mate threat starting with ...Qxc2+. So a very forcing move is required. What is more forcing than a check? 25. Qxg7+!! Kxg7
Of course, you don't go down this road unless you calculate a win. 26. Bd8+! Kh8
The alternatives are 26...Kf7 27. Bh5# and 26...Kh6 27. Rh3#. 27. Rg8+ Rxg8 28. Bf6+ Rg7 29. Bxg7+ Kg7 30. Bxd4+ Kf8 31. Bxb2 Rxb2 32. Rf1+! (avoiding the skewer ...Rb1+) 32...Ke7 33. Bc4 with an easily won endgame, up a piece (for a pawn) and a passed c-pawn. |
|
| Jun-11-21 | | goldfarbdj: First move was pretty obvious, but I didn't find Bd8 — I only looked at the double check with Bh6+, which is fine if Black takes (Rh3#) but the king can run to f7 and I couldn't find anything decisive from there. |
|
| Jun-11-21 | | malt: Black threatens ...Q:c2 and mate,
<25.Q:g7+! K:g7> where to place the bishop, gone for <26.Bd8+> rather than c1+, <26...Kh8>
(26...Kf7 27.Bh5# )
<27.Rg8+! R:g8 28.Bf6+ Rg7 29.B:g7+ Kg8 >
White can clean up with, <30.B:d4+ and 31.B:b2> |

| | chrisowen: Nd4 bubblegum part of the problem in fact no. |
|
| Jun-11-21 | | Cellist: I found the first move but then went wrong with 26.Bh6++, seeing that 26. ... KxB would lead to mate and Kh8 would (at least) lose the black Q after 27.Bg7+ and the discovered check 28.Bd4+ (followed by BxQb2). I did see that the black King can (and should) run to f7 (or f6), but I foolishly was confident that a King hunt would succeed starting with either Rg7+ or Bh5+ if Kf7, and I did not calculate further. The text move Bd8+ is great because it closes an escape hatch on f6 and indirectly also on f7 (because Kf7 would lead to Bh5#). |

| | chrisowen: Tour of force d8 no? |
|
| Jun-11-21 | | Tiggler: Qxg7 is obvious enough (what else?), but Bd8 is not. Nothing else works. |
|
| Jun-11-21 | | Cheapo by the Dozen: I came back to this one multiple times before getting it. The key to making the queen sac work is to prevent escape at f7, and Bd8 is the only way to do that. But then I still had to figure out what to do if Black's king turtled up at h8. Well, the other key to making the queen sac work is to eventually regain a queen via a profitable discovered check. That works out in the game line (as opposed to any other I looked at) because it's possible to pick up the knight along the way. |
|
| Jun-11-21 | | johnnydeep: Got the first move right, but decided the bishop should attack the queen with the discovered check move instead of blocking the other rook. That's why I'm still a patzer. |
|
| Jun-11-21 | | Walter Glattke: B) 25.Bf6?? of course Qxc2+ & Qe2# |
|
| Jun-11-21 | | 1g1yy: What I think would be nice, is to know the clock readings to know just how long it took the person to find this at the board. Several folks said this was easy, and I admit, the first move is pretty easy. But, the hard part is being the first guy to have this puzzle over the board, and not knowing there's a winning continuation to find. |

 | | MKD: Why Black didn't play Qxe5 or Nxe5? |
|
| Jun-11-21 | | Refused: Black's threatening mate in 2 (Qxc2-Qxe2)
So drastic measures are needed.
25.Qxg7+!! Kxg7 27.Bd8+! (only move otherwise the King runs to the Q-side) Kh8
So far so bad, the next sequence of moves is more or less forced so nomore exclamation points 28.Rg8+ Rxg8 29.Bf6+ Rg7 30.Bxg7+ Kg8 31.Bxd4+ +- White will capture the queen next and finish the game with an extra Bishop. Converting this shouldn't be the most difficult task in history. |
|
| Jun-11-21 | | Tiggler: <chrisowen: Tour of force d8 no?> Tour de force Oui. <Nd4 bubblegum> complete bubblegum, yes. |
|

 | | NMABQjmgChess: I was able to see the move sequence up to the subtlety of
31)Rf1+
Thanks to the kibitz by agb202 I now understand the importance behind it. |
