| Jun-05-11 | | Blunderdome: You don't see moves like 16. Bg6 every day. |
|
| Jun-05-11 | | willrazen: Indeed, could make a nice puzzle |
|
| Jun-07-11 | | holland oats: Fressinet finds a Pet move-- Petrosian vs Spassky, 1966. |
|
| Jun-08-11 | | iking: wonderful sac, 23. Qh8+ |
|
| Jun-08-11 | | DarthStapler: Nice one! |
|
| Jun-10-11 | | Jamboree: Wait a minute -- why resign?
After 23. ... Kxh8 24. Nxf7+ Kg8! 25. Nxd8 Bd5! and suddenly black is trying to get back in the game. White can probably still win with correct play, but damn, don't resign if there's still a chance your opponet can misplay it! In the position after my line above, black is threatening to win the N, and have a two-pieces vs rook endgame, so white must act quickly. Any number of inaccurate moves will let black back in the door, but I think best for white is 26. Rc1 Nd7 27. e4!, and it looks like the N escapes. There are still some tricky tactics and ways for White to blunder, but with accuracy it should be a straightforward win. But even so: Don't resign unless there is no way for your opponent to blow it! This was premature. |

| Jun-24-11 | | Tigranny: Jamboree, even if Black regains the knight, he will have a disadvantage due to White's rook, giving White a won endgame. |
|
| Jul-02-13 | | Everett: I calculated a different line, not as good: <16.Nxe6 fxe6 17.Bg6+ hxg6 <..Kf8 18.Qxe6> 18.Qxh8+ Bf8> and this is not as good as the game. |
|
| Feb-20-14 | | dfcx: 16 Bg6
Black can' take the bishop because
16 ...fxg6 17 Nxe6 
16 ...hxg6 17 Qxh8
Refusing the bishop is not better,
16 ...O-O 17 Bxh7+
16 ...Rf8 17 Bxh7 |
|
| Feb-20-14 | | Cheapo by the Dozen: Black has problems answering 16 Bg6.
If he does nothing, 17 Nxe6 wins the queen.
If 16 ... fxg6, 17 Nxe6 wins the queen anyway.
16 ... hxg6 fails because the h-pawn is pinned against the rook. Some16th moves that appear save Black's queen let White mate via e6 and f7, for example: 16 Bg6 Nb6
17 Qxe6 Rf8
18 Bxf7+ Rxf7
19 Qxf7#
Some 16th moves without that drawback allow the knight fork at f7, for example: 16 Bg6 Bd5
17 Nxf7 Qc7
18 Nxh8 hxg6
19 Nxg6
with a nice material advantage.
16 ... Nf8 allows
17 Bxf7+ Kd7 (only square)
18 Bxe6+
and White will soon be up 2 pawns and the exchange.
The only try I see for Black that avoids all of the above is 16 ... Qc7, and so my main line is: 16 Bg6 Qc7
17 Bxf7+ K moves
18 Bxe6/Qxe6,
with 2 pawns and a nasty-looking attacking position.
If I were playing this over the board, I'd go with Bg6, and sort out the 18th move in my main line if and when things got that far. |
|
| Feb-20-14 | | lost in space: Have not even considered 16. Bg6. Nice one!
My focus was on 16. Nxe6 and afterwards on Bg6. No blossoms for me today. It's not an longer Monday. |
|
| Feb-20-14 | | Cheapo by the Dozen: All that and I overlooked 16 ... O-O. :) |
|
| Feb-20-14 | | Patriot: 16.Bg6 looks really good here.
16...fxg6 17.Nxe6 (the queen is trapped)
16...Bd5 17.Nxf7
16...cxd4 17.Nxe6
16...O-O 17.Bxh7+ Kh8
Also possible is, 16.Nxe6:
16...fxe6 17.Bg6+ hxg6 18.Qxh8+ but this doesn't look as good. |
|
| Feb-20-14 | | Patriot: <Cheapo by the Dozen> <16 Bg6 Nb6 17 Qxe6 Rf8 18 Bxf7+ Rxf7 19 Qxf7#> 17...Bd5 is also a critical move here. 17.Bxf7+ Kf8 18.Nxe6+ is easier as a "test line" I think, although 17.Qxe6 is also winning. |
|
| Feb-20-14 | | PJs Studio: I found 16.Bg6 but wasn't sure what to do after 0-0. Then I found Bxh7 was best but didn't see dxc5 drawing the dark squared bishop away from the defense of the black queen. So I considered 16.Bb5 0-0 17.Rfd1 as slightly better. |
|
Feb-20-14
 | | FSR: After 16.Bg6!, threatening both f7 and Nxe6, Black's game is doubleplusungood. |
|
Feb-20-14
| | FSR: 23.Qh8+! was a cute finish. |
|
| Feb-20-14 | | abuzic: 16.Bg6 hxg6
17.Qxh8 Bf8
White wins the exchange
if 16...0-0?
17.Bxh7+ Kh8
18.e4 e5
19.f4 exd4
20.Bf5+ Kg8
21.e5

this should easily win for white. |
|
Feb-20-14
 | | al wazir: What if black had played 19...Qxd2 ? |
|
Feb-20-14
| | FSR: <al wazir> Bad dog! On 19...Qxd2, 20.Nce4! (Houdini - I confess that I was looking at other moves like 20.Bg6+) Bxe4 (20...Nxe4 21.Bg6+ Kg8 22.Qh7#; 20...Qxc1 21.Bg6+ Kg8 22.Nxf6+ Bxf6 23.Qh7#) 21.Bxe4+ Kg8 22. Bh7+ Kh8 23. Rxc8 Rxc8 24. Nxf7#. |
|
| Feb-20-14 | | M.Hassan: "Medium"
White to play 16.?
Equal
I think the most important finding about this puzzle is that if White Knight can sit on e6, Black Queen is gone!. With that in mind at first I calculated the following: 16.Qxe6 fxe6
17.Nxe6 Qc7
18.Nxc7+ Rxc7
But this way, White looses material(a Knight for two pawns) and the way to tackle this problem would be: 16.Bg7
<if...fxg7 17.Nxe6 and Black Queen will be captured>
<if...hxg6 17.Qxh8+ Bf8 and White will get advantage> 16.........0-0
17.Bxh7+ Kh8
18.e4 Bc6
19.e5 Bxa4
20.Bc2+! Kg8
21.Bxa4 Nxe5
Black can not move f6 Knight due to threat of mate
22.dxe5 Qxd2
23.exf6 Qxg5
24.fxe7
White has shattered Black |
|

 | | offramp: There was a time when black came under this sort of attack regularly in the Steinitz variation of the Caro-Kann. A quelle-version can be seen at: Van der Wiel vs Karpov, 1987. Karpov's hair must have standing on end during that excursion. Sauve qui peut! |

| Feb-20-14 | | patzer2: Missed 16. Bg6!! as the solution to Today's Thursday puzzle, but playing through the game I feel I overlooked the obvious. Can't recall a game with a Bishop (sham) sacrifice, where the win involves making a Bishop vulnerable to capture by two pawns. The last move of the game S Levitsky vs Marshall, 1912, where Marshall puts his Queen en prise with 23...Qg3!!, for capture three ways, is as close as I can come to a stunner like Fressinet's 16. Bg6!! P.S.: I think I missed it because I've come to associate winning Bishop moves with a check or the capture of a pawn or piece. Winning Bishop moves like 16. Bg6!! (involving putting a Bishop en prise without a check or capture) are surely rare. |
|
| Feb-20-14 | | Cheapo by the Dozen: <Patriot>,
I think you're correct. I overlooked that in this particular line, Nxe6 forks king and queen. And I also overlooked that bishops move backwards. :) That said, my line was one of multiple options in which White gets 2 pawns plus position -- and even if that's all one foresees, it's enough to justify the original move. ;) |
|
| Feb-20-14 | | diagonalley: wow! ... i eventually stumbled across 16.B-N6 but did not foresee such an extended continuation.... (a bit harder than 'medium' methinks) |
