 | | FSR: 31.Nf6+ Kh8 (otherwise 32.Qxg6 wins, since Black can't recapture) 32.Qxg6 fxg6 33.Nxe8 and wins, since 33...Rxe8 would be met by 34.Rxh6#. |
|

| | FSR: Ha - didn't even think of 31...Qxf6, which is doubtless the best try. |
|
| Nov-07-17 | | patzer2: My calculation was essentially the same as <FSR>'s assessment, including not giving the losing Queen sacrifice 34...Qxf6 35. Bxf6 +- any thought. For a Black improvement, instead of 16...Nh5? 17. Nxh5 ± to +- the second player can maintain a slight advantage with 16...Rae8 =/= to ∓. |

 | | Bubo bubo: Since the pawn on f7 is pinned, the black queen is only seemingly protected. White exploits this by playing 34.Nf6+! If Black wants to keep his queen he has to reply 34...Kh8, but after 35.Qxg6 fxg6 36.Nxd8 now the Pg7 is pinned, hence White threatens Rxh6#. So Black cannot afford to recapture and is down two pieces against two pawns. (White then only has to avoid one really dumb blunder: 36...Rf2+ 37.Kb3?? a4#) |
|
| Nov-07-17 | | AlicesKnight: 34.Nf6+ nets the Black Q for 2 minor pieces (thanks to the pin on f7) or a R after ...kh8; 35.Qxg6 fxg6; 36.Nxe8 and Black cannot recapture because of the threat Rxh6#. Let's see - others agree..... |
|
| Nov-07-17 | | malt: Got the same as <FSR> 34.Nf6+! Kh8 35.Q:g6 fg6 36.N:e8 Rf2+
(36...R:e8 37.R:h6# )or
(36...Kh7 37.N:g7 ) 37.Kd3 |
|
| Nov-07-17 | | patzer2: According to our Stockfish 8 engine, Black could have equalized with 22...Rae8 23.Nf4 Rxe3 24.Bxe3 Bxf4 25.Qd3 Qg3+ 26.Ke2 Qg4+ 27.Kf2 =
0.00 (21 ply) when a draw by repetition is best for both sides. |
|
| Nov-07-17 | | saturn2: Got 34 Nf6 Kh8 (what else?)
And after 35 QxQ fxQ 36 NxR it is a prosaic win for white. |

| Nov-07-17 | | TheaN: Good afternoon CG!
I have no idea how long it has been since I've solved one of these, but as my chess strength is a bit in disamay I thought I may as well pick up the CG puzzles again. Immediately I notice I'm sloppy on the tactics side, as I completely missed a sideline. Material: unbalanced even, <B+N v R+2P> <34?> Of course, the main move is obvious. White utilizes the pin on f7 with <34.Nf6+>. A: <34....gxf6? 35.Qxg6+ Kh8 36.Rxh6# 1-0> utilizing the pin to its fullest. B: <34....Kh8> I missed that this line solves the pin and stopped after <35.Qxg6>. Of course, including <35....fxg6 36.Nxe8 +-> is required on the verdict of <36....Rxe8? 37.Rxh6#> utilizing the other pin. C: <34....Qxf6 35.Bxf6 +-> is winning for white and the line I considered the best for Black regardless. There is some play left but it is easily neutralized. |
|
| Nov-07-17 | | Cheapo by the Dozen: Step 1: Try to find something involving Rg1. Give up after realizing that White just can't create a way to protect g1. Step 2: Quickly find the actual game move. |
|
| Nov-07-17 | | Olsonist: There's a pin. Now how do I exploit this pin? |
|
| Nov-07-17 | | kevin86: Black must lose the queen! |

 | | Breunor: Running Stockfish at various points, I'm getting the game is even after 23... B xh4 ch and is at about .24 after .... 30 c x d5. It looks like things start going badly with 31 ... Qb6 instead of Qc8 when Stockfish goes to over a pawn lead for white. |
|

| | Breunor: Sorry, hit send too soon.
The game gets out of hand with 32 ... Be7 leaving white with an advantage of over 2; Re5 keeps it at .95. |
|
| Nov-07-17 | | patzer2: <Breunor> While Black did have difficult equality for quite a while in the game, I think Black's problems started with 16...Nh5? which misses the opportunity for an advantage with 16...Rae8 ⩱ to ∓. Our chessgames.com Stockfish 8 engine gives:
-0.58 (18 ply) 16...Rae8 17.Kg2 Re7 18.a4 Bxf4 19.exf4 h5 20.Nd1 Nc8 21.Bb4 Nd6 22.Ne3 Rfe8 23.Rc3 b6 24.Be2 Bf5 25.Bxd6 Qxd6 No doubt a comfortable advantage for Black with 16...Rae8 ⩱ to ∓, instead of 16...Nh5? =, would have made the job of keeping things level or better much easier for the second player. |
|
| Nov-07-17 | | Marmot PFL: Surprisingly easy, 33...Qg6 must have been a time trouble blunder. |
|
| Nov-07-17 | | BOSTER: < FSR ><31.Nf6+>.
You have wrong numbers. |
|
| Nov-07-17 | | patzer2: <Marmot PFL: Surprisingly easy, 33...Qg6 must have been a time trouble blunder.> I agree. Our chessgames.com Stockfish 8 engine gives 33...Kh8 34.Rg1 f6 35.Bd4 Qc7+ 36.Kb1 Qh2 37.Rf1 b4 38.Nc5 Rd8 39.Qf5 Rxd5 40.Qxd5 Rd8 41.Qf5 Bxc5 42.Qxc5 Qg2 43.Rc1 Qd5 44.Qc2 Qh5 45.Qc7 Qf5+ 46.Ka1 Re8 47.Qc6 Rd8 ± to +- ( +1.76 @ 21 ply). Though the resulting position clearly favors White, it's not yet a clear forced win after this computer analysis. |
