Oct-31-13  trnbg: After 16. Bg5 Bxf1 17. Rxf1 h6, why not simply 18. Bxf6 Bxf6 19. Qxf6 Qxf6 20. Rxf6 ? This should win easily for White: Two pieces for a rook, and Black cannot defend the pawns f7 and g6.
Oct-31-13  diagonalley: <trnbg> yep... i took this line too and thought it must be the solution... the game line constitutes a very hard puzzle for a thursday! i think we deserve the full point.
Oct-31-13  Kikoman: <Puzzle of the Day>

I also went for <16. Nxf7> and totally missed Thursday's puzzle! Oh well, better luck next time. :)

Oct-31-13  morfishine: Not a whole lot of candidates to sort thru. 16.Bg5 emerges as best

<16.Bg5> increases the pressure on f6 (and indirectly f7)

<16...Bxf1> practically forced as Black must grab as much material as possible

<17.Rxf1> The simplest and most direct solution

<17...h6 18.Bxf6 Bxf6 19.Qxf6 Qxf6 20.Rxf6> For an exchange, White has won a piece:

PM: At first, I thought <17.Ne4> was just as effective in the above line; but its not as accurate as 17.Rxf1 (which serves the double purpose of removing a developed Black piece while completing White's development). In any case, I overlooked 18.Nxg6, which wins in a more "Grandmasterly" way

  agb2002: The material is identical.

Black tries 16... Bxf1.

The knight on b4 would be trapped after 16.a3, but after 16... Bxf1 17.Qxf1 bxc5 18.axb4 cxd4 both white knights hang and Black has a rook and two pawns for the bishop and the knight.

The rook on f8 is overworked since it defends the rook on a8 and the pawn on f7. However, 16.Bxf7+ Kg8 17.Nxg6+ hxg6 seems to go nowhere (18.Qh3+ Nh5 19.Bxg6 Rxf1#).

White can try to win two pieces for a rook by pinning the knight on f6 with 16.Bg5:

A) 16... Bxf1 17.Rxf1

A.1) 17... bxc5 18.Ng4 cxd4 19.Axf6 (19.Nxf6+ Bxf6 20.Bxf6 Qe3+) followed by Nce4 and White seems to have an overwhelming attack.

A.2) 17... Rad8 18.Ng4 looks similar to A.1.

B) 16... Rad8 17.Bxf6 Bxf6 18.Qxf6 Qxf6 19.Rxf6 wins a piece.


Another option is 16.Re1, threatening 17.Bxf7+ and 18.Nxg6+ but after 16... Nd7, avoiding the pin and taking advantage of the defenseless rook on e1, 17.Bxf7+ Rxf7 18.Qxa8+ Rf8 19.Qxa7 Bxe5 the position looks very risky for the white king.


I think 16.Bg5 is preferable.

Oct-31-13  Jakob52: Maybe 16.Bxf7 is playable too? If 16...Rxf7 then Ra8 hangs so it's best for black to play Kh8. Then 17.Bg5.
Oct-31-13  Nick46: Like zb2cr and Kikoman I too went for <16. Nxf7> Why is it no good, SVP ?

  paulalbert: I first looked at Bg5 as the logical idea to put additional pressure on f6, but thought it was too mundane for a typical puzzle, so spent all my time looking at Bxf7+ and Nxf7 trying to come up with a killer variation seeing the possible vulnerability of black's R on a8 and maybe some eventual Nxg6 ideas if the B takes along with the Q going to h3 if Black's K just goes to h8. Finally I gave up and looked. From the comments of others, it seems I was not alone at striking out on this position.
Oct-31-13  Gryz: If white plays 16. Nxf7, then black answers Bxf1. White can not take back with Ra1xf1. White has as best equal play with 17. Bd2, Ba6.
Oct-31-13  Nick46: Dank u.

  beenthere240: The combo only needs to be calculated to move 20, when it's clear that the knight can regain the exchange with Nxf8 AND either get out of Dodge via d7 and e5 or be exchanged for the black rook at a8. The rest of the game is really irrelevant to the combination.
Oct-31-13  LoveThatJoker: <16. Bg5 Bxf1>

(16...Bb7 17. Qxb7 )

<17. Rxf1>


Oct-31-13  Pedro Fernandez: 57 y.o. and a 16 moves combination, impressive!!

P.S. Yeah, 16.Bg5 wasn't too hard to find.

  kevin86: Mr. Keene goes down quickly in this one. It seemed like all of his pieces were under fire at the same time.
Oct-31-13  LIzzard: I got caught up with
17: bxf7+ - perhaps not the best solution, but it does win some material if black takes with the rook. Any other response gives white a very strong advantage.
Oct-31-13  jrbleau: I don't think you have to see "everything" after 16 Bg5 - you only need to calculate to advantage. After 16...Bf1 17 Rf1, the f6N is doomed and W winds up with two pieces for the R.
Oct-31-13  tcoxon39: 16. Bg5 seems good, leading to a rook/bishop trade, but after 17...h6 I was a little stumped because my narrow vision didn't see the b3 bishop. Seeing that, 18. Nxg6 is pretty obvious.

I'll count this as partially solved.

Oct-31-13  MiCrooks: All the talk of too hard...Bg5 not only wins two pieces for the "sacked" Rook but then also increases the pressure on f7 ultimately winning more material. This IS one where you are not going to work the whole combination out to checkmate or a huge material advantage, but the advantage there is real and clearly winning.
Oct-31-13  MiCrooks: h6 is not Black's best response, and it leads to another problem (i.e. do you play Nxg6 instead of winning the two pieces as originally planned), but White does not have to accept that challenge. Against best defense (Qd8 for example) he would be happy to just take the piece and have two pieces and a pawn and pressure on f7 in return for the Rook. That game is easily won. But Ng6 is calling out to be played and is in fact somewhat better as White comes out with an exchange and pawns and play against the exposed Black King. Still seeing Nxg6 cannot be said to be part of today's puzzle since it depends upon suboptimal moves by Black AND White CAN stick with his original plan. If h6 forced White to find Nxg6 then it could be considered part of the puzzle. As it stands, the level seems reasonable for a Thursday. The only "hard" thing about it is that we get so used to forcing combinations leading to totally settled positions--mate, huge material gain, etc.

  Penguincw: Wow. This combination seems simple enough.
Oct-31-13  Patriot: Black threatens ...Bxf1.

16.Bg5 seems to win a piece for the exchange.

16...Bxf1 17.Rxf1 looks pretty convincing.

I'm not sure what else is important here.

Oct-31-13  Patriot: <morf> Nice job!!

<In any case, I overlooked 18.Nxg6, which wins in a more "Grandmasterly" way> Very true. When thinking ahead though, in my opinion it would be a mistake to look for the best winning line unless you have time and you're trying to compare several beginning candidates to see which one is best. Here it is pretty clear that 16.Bg5 is the best option, so no need to be completely accurate. I would be more concerned about finding the best move after reaching the position however (not when looking ahead).

Oct-31-13  simsan: I went for the somewhat inferior line with 18.Bxf6 and not the game continuation. Calculated it to the point where I felt secure that the sustained pressure on f7 would allow white to remain with the initiative.

However, when I now study this variation with an engine it seems that even though the 18.Bxf6 strongly favours white, it is possible for black to regain some initiative and force white to make some precise moves to keep his pieces coordinated. In the game continuation white seems to have more control.

I'll award myself half a point. Do I deserve that?

  patzer2: Count me among those who tried 16. Bxf7+!? instead of the surprisingly strong pin 16. Bg5!! What makes the puzzle solution so difficult and enjoyable are the strong surprise follow-up moves such as 18. Nxg6! and 20. Nd7!

If 20...Nxd7, it would appear 21. Bxf7+ Kf8 (21...Kh7 22. Qh5+ Bh6 23. Qg6+ Kh8 24. Qxh6#) 22. Bd5+ wins easily.
