|Jun-21-07|| ||moppa: I intended to play queen to h6, to force ...Rg8 and only after that Ng5. The game continuation was the first line I saw - but I had to think about five minutes to see that white doesn't need to play Qh6 and therefore considered 16...Nd8 as a tough defence, before seing that white can play 17.Ng5 straight away. :)|
|Jun-21-07|| ||chad47474: if 15. Bf6 Kg8 then 16. Qg5 g6 17. Qh6 ... 18. Qg7#|
|Jun-21-07|| ||Crowaholic: 15. Bf6 - easy enough.
Now 15. ..gxf6 (basically forced) 16. Qxf6+ Kg8 17. Ng5 f4! stalling the attack by giving Black defensive options along the diagonals.
What about 16. exf6 threatening Qh6 and Qg7#?
16. ..Rg8? 17. Ng5 Rxg5 18. Qxg5 game over.
Alternatively, Black survives just a little bit longer with
16. ..Rg8 17. Ng5 Rg7! 18. Qh6 Rxg5 19. Qxg5
In any case, White will mate soon. That looks better for White! But 16. ..Rg8 is not forced. Black has
16. ..Qxf3 17. gxf3 Rg8+ 18. Kh1
and, for now, the black king is safe. But now White has a Q for B+N and should win later on.
|Jun-21-07|| ||Crowaholic: Now that I looked at the solution, I must say that Black defended rather poorly. It should be obvious that the 16. ..Rg8 defense does not work because of 17. Ng5. Personally, I would either have tried to struggle on with 16. ..Qxf3 or resigned right away after 16. exf6, depending on the overall strength of my opponent.|
|Jun-21-07|| ||MostlyAverageJoe: <Gilmoy> OOPS. Somehow I forgot about your [B4] line and repeated it for <tarek1> instead of referencing your post.|
16...f4 was yet *another* line I missed, and since it doesn't even show up in computer analysis (because of the very quick forced mate), I actually had to work it out myself after <tarek1>'s post ...
|Jun-21-07|| ||YouRang: Not too hard. Upon seeing the position of the pieces, it seemed pretty clear that:|
(1) it was going to be an attack on the king position,
(2) the only white pieces involved are the queen, bishop, knight and Pe5,
(3) the knight really needs to be on g5, where the bishop resides: calling for a clearance sac!
It doesn't take long to see that 15. Bf6! was the move, which prevents black from defending against 16. Ng5, but taking the bishop cracks black's defense puts a killer pawn on f6 -- and the threat of Ng5 remains.
|Jun-21-07|| ||kevin86: Surprizingly simple for a Thursday. The bishop sacrifice was obvious. Then, white recaptures with a pawn to enable mate threats at g7-finally, he brings in the knight for threats on h7. Black cannot stop both-and is lost.|
A simple puzzle-but a strong lesson in tactics.
|Jun-21-07|| ||MikeChesss: I got it, so it must be easy (I'm usually out of action after Tuesday). I saw the bishop sac, followed by black moving his rook to the g-file. Then you just bring up the knight, which sets up a mate threat, forcing black to sac the exchange and putting White's queen on the road to mate.|
|Jun-21-07|| ||Crowaholic: <kevin86: Black cannot stop both-and is lost.>|
Actually Black can defend against both threats with 16. ..Qxf3, as several kibitzers have pointed out. After 17. gxf3 Rg8+ 18. Kh1 Be6 19. Rg1 White has new mate threats, but Black has 19. ..Rg6! (other moves allow White to exchange rooks and mate Qh4-h6-g7) 20. Rxg6 fxg6 21. Rg1 Rg8 and the rook lift mate threat fails to f4 giving Black enough tempi to bring the knight into the equation.
In the longer term, Black is still dead lost, of course.
|Jun-21-07|| ||newton296: white's central pawns clogg the A1- g8 diagnal so they keep black's Q from coming to the kings rescue . So Bf6 !! and white threatens to play Ng5 with mate at h7 and black only has the game continuation or the Q sac ...
qxf3 ( uggly! I would rather be mated) to prevent mate.|
|Jun-21-07|| ||newton296: I play the french sometimes and can tell You from experience that 9)...Nf5!? as played in this game can look strong but ng6 is a much better play. at g6 black's knight is covered by 2 pawns and at g6 the knight shuts down white's ambitions of a quick kingside attack. tss ! tss! for not knowing even basic french theory nebal!|
|Jun-21-07|| ||newton296: Ng6 is especially called for against aggresive Qg4 lines. the early 7)Qg4 forshadows white's aggresive intentions to go for a big kingside attack.|
|Jun-21-07|| ||twin phoenix: hey <mostlyaveragejoe> i noticed chess games has started giving a difficulty rating now. probably a testiment to you since you started giving ratings via computer. nice to see how you can encourage changes, huh?!|
|Jun-21-07|| ||Marmot PFL: <newton296> How would you meet 9...Ng6 10.h4?|
|Jun-21-07|| ||dabearsrock1010: I actually saw Bh6 first, and calculating that gave me the correct idea Bf6...im en fuego this week|
|Jun-21-07|| ||vibes43: Good puzzle. Missed exf6.|
|Jun-21-07|| ||patzer2: For today's puzzle solution, the pawn demolition sacrifice 15. Bf6! initiates a mating attack.|
|Jun-21-07|| ||TopaLove: I spent some time analizing 15.Bd2. If the c2 pawn were defended it would trap the queen in the next move.
We had more than one candidate move.|
|Jun-21-07|| ||chessgames.com: <ianD: very easy puzzle. There is only one credible move at each point in the solution and the initial move is obvious.> Not true. As others have pointed out, after 15. Bf6 gxf6 the move 16.Qxf6+? is a very credible move, and that bad move lured a lot of posters here. Furthermore, after there is the critical defense 15.Bf6 f4, and many people were unable to visualize the one and only move to break through, which is 16.Qh6! (...Rg8 17.Ng5).|
We'd rank this a perfect Thursday puzzle, the proof being simply the large number of people here who were fooled by it.
|Jun-21-07|| ||schnarre: Got this one right away! Once the Bishop is on the f6 square, Black's had it!|
|Jun-21-07|| ||MostlyAverageJoe: <twin phoenix: hey <mostlyaveragejoe> i noticed chess games has started giving a difficulty rating now. probably a testiment to you since you started giving ratings via computer>|
Alas, I cannot take a credit for inducing that change. It was needed because the daily puzzle can be outsourced to other websites (see ChessGames.com Webmaster Resources), where the readers may not be familiar with the Monday-Sunday difficulty scales.
<chessgames.com: We'd rank this a perfect Thursday puzzle> What a coincidence. So do I :-)
|Jun-21-07|| ||THE pawn: Wow, that wasn't easy! At first I thought Bf6, then Qxf6+ but with a bit of calculation you know this is wrong. After exf6 it's over BUT I didn't take the bishop with black and instead played f4 and I just couldn't see Qh6!....
really nice puzzle.
|Jun-21-07|| ||THE pawn: <chessgames> wow...I am the EXACT description you gave.|
|Jun-21-07|| ||Counterpoint: if 15...Qxc2 16.Bxg7+ Kxg7 17.Ng5 f4 and then what?|
|Jun-25-07|| ||Crowaholic: <Counterpoint: if 15...Qxc2 16.Bxg7+ Kxg7 17.Ng5 f4 and then what?>|
Actually, 15. ..Qxc2 16. Qh6! Rg8 17. Ng5 f4 18. Nxf7# as you might have guessed from the comments on 15. Bf6 f4.
