|Aug-03-17|| ||dfcx: 11.Bxh7 wins a pawn. Black must refuse the pawn or be mated.|
12.Ng5+ Kg8 (longest defense)
|Aug-03-17|| ||al wazir: I wanted to go after the smothered ♕. For example, in the game line, 13. Nxe6 fxe6 14. Nxe6 Ba6 15. Nxd8 Raxd8. White has ♕+♙+♙+♙ vs. ♘+♘+♗, which ought to win.|
|Aug-03-17|| ||Walter Glattke: Refuse does not help, 11.-Kh8 or 11.-Kf8
get deciding attack, too.
|Aug-03-17|| ||agb2002: Another example of the attack which starts with 11.Bxh7+:|
A) 11... Kxh7 12.Ng5+
A.1) 12... Bxg5 13.hxg5+ Kg8 14.Qh5 f5(6) 15.Qh8+ Kf7 16.g6#.
A.2) 12... Kh6 13.Qh5#.
A.3) 12... Kg8 13.Qh5
A.3.a) 13... Bxg5 14.hxg5 transposes to A.1.
A.3.b) 13... Nf8 14.Qxf7+ Kh8 15.Nxe6 Bf6 (15... Nxe6 16.Qh5+ Kg8 17.Qh7+ Kf8 18.Qh8#) 16.Nxd8 wins decisive material.
A.3.c) 13... Nf6 14.Qxf7+ Kh8 15.Ng6#.
A.4) 12... Kh8 13.Qh5+ Kg8 14.Qh7+ (or 14.Qxf7+ Kh8 15.Ng6#) 14... Kf8 15.Qh8#.
B) 11... Kh8 12.Ng5
B.1) 12... Bxg5 13.hxg5
B.1.a) 13... Qxg5 14.Ng6+ wins decisive material.
B.1.b) 13... Nf8 14.Bg6+ Kg8 15.Rh8+ Kxh8 16.Qh5+ Kg8 17.Bxf7#.
B.2) 12... Rf8 13.Qh5 and mate soon (13... Bxg5 14.hxg5 Re8 15.Bg6+ Kg8 16.Qh8#).
B.3) 12... Qc7 13.Qh5 again with a winning attack.
C) 11... Kf8 12.Ng5, with an extra pawn and attack, looks similar to previous lines.

|Aug-03-17|| ||gofer: The bishop sacrifice on h7 is <too> attractive. It is like an old friend
that we want to be the answer regardless of whether it is or not. I wonder
how many of us see the sac and only look at the combiniations from that

Okay, white is clearly winning and will eventually set up
1 Bh6 any move 2 Qg7# against which there is no defence,
but it will take a while, but black can probably resign at
Okay, I missed <dfcx>'s <15 h5>, which is rather nice!
|Aug-03-17|| ||whiteshark: There are 3 necessary criterias for a Bxh7+ sacrifice, and here there are 6 of them,|
<11.Bxh7+!!>, and that's it.
|Aug-03-17|| ||offramp: I went with 11. b3, to tighten the grip on c4.|
|Aug-03-17|| ||patzer2: When I saw today's Thursday puzzle position (11. ?), I immediately thought of two words: demolition and charge.|
By that I meant sacrifice the Bishop in a demolition combination with 11. Bxh7+! Kxh7, and then follow-up with the Knight with 12. Ng5+ to clear the way for the advance of the Queen with 13. Qh5 .
It wasn't until 14...Kf8 that I really had to give the combination more than a moment's thought, before I realized it's mate-in-three after 15. Qh8+ Kf7 16. Ng6+ fxg6 17. Qg7#.
P.S.: Black's decisive mistake appears to be 9...b6?, allowing 10. h4! (+1.80 @ 27 depth, Stockfish 8.) Of course 10...Re8?? allowing 11. Bxh7+! (+5.31 @ 28 depth, Stockfish 8) made it even easier for White.
Instead, 9...cxd4 10. cxd4 Bb4+ 11. Kf1 (+0.95 @ 27 depth, Stockfish 8) and 10...g6 11. h5 g5 12. Ng6 to (+1.72 @ 28 depth, Stockfish 8) put up more resistance.
Earlier for Black in this French Defense, I prefer the popular move 7...cxd4 as in the recent draws in J C Schroeder vs A Ra Harikrishnan, 2017 and Lin Chen vs Yiye Wang, 2017 or Black's win in Aditya Munshi vs Graham J Moore, 2017.
|Aug-03-17|| ||stacase: 8. ...O-O was Black's downfall. I wouldn't have done it - nearly all of White's power was focused on breaking that side of the board wide open!|
|Aug-03-17|| ||takchess: Busted on this one.... didn't see that black can't take knight due to the pawn x g5+. I didn't take into account the h file rook. As Purdy said sometimes it is more important to look around than to look ahead...... A sweet combination.|

|Aug-03-17|| ||AylerKupp: <StevieB> Particularly when you're oblivious to the dangers of a White bishop on d3, an open b1-h7 diagonal, a White rook on h1, and an advanced Ph4 ready to advance and open the h-file, particularly with no knight on f6 or f8 defending h7.|
One could almost think that Black had never played the French before.
|Aug-03-17|| ||morfishine: <11.Bxh7+> Standard stuff vs French dedense|
|Aug-03-17|| ||ColeTrane: The real beauty is 16. Ng6|
|Aug-03-17|| ||patzer2: <stacase: 8...O-O was Black's downfall.> I'm not particularly fond of Black's position after 8...0-0, allowing 9. Nf5 +/- (+0.93 @ 28 depth, Stockfish 8), even though I'm also not convinced the second player's hopelessly lost at that point.|
Still, I agree with you that Black should be able to improve over 8...0-0.
It's possible Black might catch White unprepared and get a decent game after 8...Qb6 (the most popular reply to 8...0-0) as in Blacks's win in D Vella vs M Chogdov, 2010 or after 8...a5 (the second most popular reply to 8...0-0) as in the draw in F Braeuer vs M Michna, 2016.
However, after the Stockfish 8 best moves 8...Qb6 9. 0-0 0-0 10. a3 +/- (+0.72 @ 28 depth) or 8...a5 9. h4 10. Rh3 Ba6 11. Bxa6 Rxa6 12. Rg3 +/= (+0.46 @ 28 depth) I still find Black's position unpleasant.
For this reason, I prefer to look one move earlier to the very popular move 7...cxd4 (to view the overwhelming, majority, Master preference for this move click on Opening Explorer) for a Black improvement.
|Aug-03-17|| ||Yuridmi: Nothing is new under the Sun or Caissa's gaze. This position is #958 in Fred Reinfeld's 1955 classic, "1001 Brilliant Chess Sacrifices and Combinations." Check it out: https://www.scribd.com/doc/19962553...|
Back in 5th grade (~ 1968) I struggled to solve this position.
|Aug-03-17|| ||drollere: i started with 11. Nxe6 as the pawn recapture is forced to save the Q and this clears the QB diagonal. then 12. Bxh7+ follows as in the game (h6, 13. Bxh6 also destroys black's position). |
the end tactics appear to be the same, since instead of Ng6+ white has g6+. if Kxg6 then Qh5#, if Ke7 then Qxg7#.
|Aug-03-17|| ||DarthStapler: I got the overall idea even if I didn't see every line|
