| Oct-25-06 | | Counterpoint: 20...g3 21.fxg3 Qxg3+ 22.Kh1 Qh3+ 23.Kg1 Rg8+ 24.Kf2 Qg3# is more forcing. |
|
| Oct-25-06 | | Craigokat: 20...g3 looks like a winner too |
|
| Oct-25-06 | | chessmoron: <Counterpoint> But 24. Bg4 stops the mate. |
|
| Oct-25-06 | | syracrophy: A lovely example of a double bishop sacrifice on this modern days, in a romantic style. For more examples, visit the great collection of <patzer2>: Game Collection: Demolition of Pawn Structure: Sac on h7 (h2). |
|
| Oct-25-06 | | Counterpoint: <chessmoron> so does 21.Bxg4. I guess the rook on h8 can later move g8 - problem solved. |
|
| Oct-25-06 | | chessmoron: To finish off the mate: 21...Rg6 22. Ne4 Rh6 23. Nd6+ Kf8 24. Nxf7 Qh3# |
|
| Oct-25-06 | | goldfarbdj: I saw the moves of the game easily enough up to black's 20th, since I've seen the double-bishop sac before. Like Counterpoint, I expected 20 ... g3, and I saw the line he gave. Chessmoron is right, though: after 24 Bg4 Rxg4 25 Qxg4 Qxg4 26 Rf2 (threatening 27 Rg1 and Rg8+) black is up material but his queen is exposed. 20 ... Rg8 is stronger. |
|
| Oct-25-06 | | dzechiel: <Counterpoint> I looked at the 20...g3 line as well, but it seemed to me that after 23 Rg8+ that white could toss the bishop in order to give the king a flight square and avoid the checkmate. |
|
| Oct-25-06 | | YouRang: Crap. I saw the whole line up to 20. Kg1, but didn't see the 'punchline'. :-( If I had been more alert, I would have noticed that White's defense is so pathetic that Black can leisurely bring his rook into the attack from h8-g8-g6-h6  . |
|
| Oct-25-06 | | TrueFiendish: It's funny. You kinda don't think the rook will have time to mosey all the way from h8, or I didn't anyway. |
|
| Oct-25-06 | | ahatchu: Instead of 16.Nd2, would 16.Ne1 be sufficient to counter the attack? Or would it have been better to take care of the threat earlier on seeing 12...g5 by 13.Nxe4 Bxe4 14.Nd2? I'm interested in other suggestions on what would be sufficient to counter the attack. |

 | | al wazir: I think 16...Qh4 also wins:
A) 16. h3 Bxg2, with multiple threats.
B) 16. g3 Qh3, and white must lose a piece by 17. Nf3 or Bf3 (If 17. f3, then 17...Bxg3 18. hxg3 Qxg3+ 19. Kh1 Qh3+ 20. Kg1 g3). C) 16. f4 gxf3 17. Nxf3 Bxf3 18. Rxf3 Qxh7+ 19. Kf2 (19. Kf1 Qh1+ 20. Kf2 Qh4+, etc.) Qh4+ 21. g3 (21. Kg1 Rg8 22. Bf1 Bg3) Qh2+ 22. Ke1 Bxg3+. Not as dramatic as the double ♗ sac, but a win is a win. |
|
| Oct-25-06 | | prinsallan: Nice touch. Even I got it ;D |
|
| Oct-25-06 | | Marco65: <al wazir> 16...Qh4 17.g3 Qh3 18.Nxe4 As <Counterpoint> I'd have played 20...g3. I think it's equivalent to the text, also after 20...Rg8 White could have played 21.Bxg4 Rxg4+ 22.Qxg4 Qxg4+ avoiding mate, but not the loss of the game of course. Anyway my real issue is with 19.f4, I'm not able to find a winning line with that and I expected Lebel to play that. Some lines: 19...Qg3 20.Qe1 and now?
19...Qh1+ 20.Kf2 Qh2 21.Ke1 and now?
19...g3 20.Kxg2 Qh2+ 21.Kf3 and now? |
|
| Oct-25-06 | | mpl: <Marco65> 19. f4 ♕h1+ 20. ♔f2 g3+ 21. ♔xg3 ♖g8+ 22. ♗g4 and after exchanging everything on f1 black playes f5, winning the bishop on g4 and the game... |
|
| Oct-25-06 | | alfilbueno: <Marco65,mpl>
White also loses if White's king goes to e1 instead of taking on g3:
19 f4 Qh1+ 20 Kf2 g3+ 21 Ke1 Bxf1 22 Nxf1 g2 and next 23 ...g1=Q. Also, if 22 Bxf1 g2 23 Nf3 gxf1=Q, Black's g-pawn cannot be stopped. |
|
| Oct-25-06 | | Marco65: <alfilbueno><mpl> That's right, thanks |
|
| Oct-25-06 | | Fisheremon: <al wazir> Let me add (and correct) a bit with 16...Qh4
1) 17...h3? Bxg2 is clear
2) 17. g3 Qh3 18. Nxf3 (or Bxf3) gxf3 19. Bxf3 (or Nxf3) 20. Nf6 and White loses Queen
3) 17. f4 gxf3 18. Nxf3 Bxf3 19. Rxf3 Bxh2+ 20. Kf1 Bg3 21. Rxg3 Qxg3 22. Bf3 h5 As <Counterpoint> suggested 20...g3 (instead of 20...Rg8 in the game) 21.fxg3 Qxg3+ 22.Kh1 Qh3+ 23.Kg1 Rg8+ 24.Bg4 (<Chessmoron>) Rxg4 26. Qxg4
Qxg4+ 27. Kf2 and Black has to work more.
It's quite different with 21. Bxg4 (instead of 21. Qe1 in the game), e.g. Rxg4 22. Qxg4 Qxg4+ 23. Kh2 Qh5+ 23. Kg2 Ke7 24. Rg1 Qe2 with mate attack continuing. The point is that if White could move pawn f2 it might have more pieces to defending the King. So double sac as in the game is the only shortest way to the win. |

 | | Chnebelgrind: it's clearly superior to my choice 16... ♘xc5 |
|
| Oct-25-06 | | greensfield: Missed 20...Rg8 etc |
|

 | | Richard Taylor: One of those positions where Black has about 10 ways to win - if he couldn't see Bxh7+ he should have been banned from playing Chess. |
|
| Oct-25-06 | | dakgootje: <One of those positions where Black has about 10 ways to win - if he couldn't see Bxh7+ he should have been banned from playing Chess.> Indeed! Killing your own pawns is one of the most used tactics around, he obviously should have seen that one. |
|
| Oct-25-06 | | ARival: <Richard> interesting to compare this double B sac with the one in Zgy Frankel v Mariner that Jonathan posted on your forum. |
|

 | | Sneaky: This ♗♗ sac is a little different from most. Usually once the king is stripped bare naked, a rook lifts to deliver the final blow. Well that happens here too, but the rook isn't all ready to go in "lift position", it takes a few moves to get mobile! |
|
| Oct-25-06 | | Marco65: <Richard Taylor> <if he couldn't see Bxh7+...> That double bishop sacrifice is a classic, but one thing is to "see", another is to "calculate". Could you calculate all possible defence lines up to a clear win for Black? Congratulations. I couldn't (see my previous posts about 19.f4) and I don't think I'm alone. I found this a difficult puzzle. |
