| Sep-08-17 | | Altairvega: Black has two concerns 1. to give the formidable check on h1. 2. To avoid capturing of his own rook h8 by the white B. The two goals are achieved with the knight move 39..Nxf5.40 gxf5 Rh1+ 41. Kg2 R8h2+ 42. Qh2 Qxb2+ and the whire Queen is lost. If 41. Kf2 then ..Qxb2+ 42.Re2 W8h2+ the rook in e2 is lost. Etc.. |

| Sep-08-17 | | Walter Glattke: I think, a grandmaster would play 43.-Qxc3+ here. 44.Kg2 Qc2+ 45.Kf3 Qxf5+ 46.Rf4 Qd3+ 47.Kf5 Rxe1 48.Qxd3 cxd3 49.Bxh8 d2 50.Rd4 d1Q 51.Rxd1 Rxd1 |

| Sep-08-17 | | AlicesKnight: Found the key moves in (....Nxf5, ...Rh1, ...Qxb2 etc.). Black must guard against the h8 mate but the attack from both wings is very good. |
|
| Sep-08-17 | | MrCarciofo: What about ...Qxb2 immediately? |

|
| Sep-08-17 | | morfishine: I gather the key here is seeing <Qxb2>, whether its check or not, at some point ***** |
|
| Sep-08-17 | | gofer: Well again the start of this one is simple. We want to play Rh1+ followed by Qxb2+, but we don't want to move the Knight to f3 as that
allows Qxf3 protecting Rh1+ (likewise with g2), so that just leaves one possible knight move... <39 ... Nxf5>

click for larger viewAt this point, I was wondering which rook to move, the one that is attacked by the bishop or the one attacked by the rook? Either way we aren't actually getting a piece out of being "en-prise", but by moving
Rh8 we are attacking two of white's pieces, instead of just one, so to my mind I think I would move Rh8. <42 ... R8h3>

Hmmm, almost right. I chose the wrong rook!? |

| Sep-08-17 | | Cheapo by the Dozen: As was more-or-less said before:
-- The knight needs to be unblocked with tempo, and attacking the queen is the way to do it. -- ... Qxb2+ is the way to get the queen in on the attack. -- White's queen easily gets pinned and won. The trick is not to leave him with both rooks. -- His rooks are loose enough that this part of the challenge isn't too difficult. -- The position is complicated enough that calculating EVERY variation in advance would be time-consuming. |

| Sep-08-17 | | Cheapo by the Dozen: And for a cheap pun we could go with "Tennen bombs". |

| Sep-08-17 | | patzer2: Solved today's Friday (39...?) puzzle more or less by process of elimination. I first looked at the puzzle around 5:30 am and thought it was White to move. After I fully woke up and looked at the puzzle a second time, and realized it's Black to move, it was a lot easier to calculate. Once I took the time to visualize 39...Nxf5! everything fell in place. In the forcing sequence 39...Nxf5! 40. gxf5 Rh8+ 41. Kg2 Qxb2+! -+, Black obviously has White in a mating web. After 42. Kf3, I went with 42...Qxc3+ -+ (mate-in-twelve, Stockfish 8) instead of the more efficient 42...Rxe1 -+ (mate-in-nine, Stockfish 8.) The game move 42...R1h3 -+ (mate-in-25, Stockfish 8) is also clearly winning. P.S.: For an improvement for the losing side, White should have ditched 38. Bg5? which potentially allows 38...gxf5 ∓ (-0.75 @ 35 depth, Stockfish 8.) Instead, White would have been winning after 38. fxe6 fxe6 39. Rf1 +- (+1.78 @ 31 depth, Stockfish 8.) |

|
| Sep-08-17 | | Pawn Slayer: I remember the Fischer motto: if you see a good move, don't play it - there might be a better one. 42 ....R8h6 wins but allows white to struggle on. I preferred 42 ....Qxc3+ when white's best response is
43 resigns. |

| Sep-08-17 | | ughaibu: <I remember the Fischer motto: if you see a good move, don't play it - there might be a better one.> How on Earth did advice from Lasker become "the Fischer motto"? |
|
| Sep-08-17 | | malt: from one my lines,
<42.Kf3 R8h3 43.R:h1 Q:c3+ 44.Ke2 Q:g3>
White could play

| Sep-08-17 | | kevin86: Must be queen-pinning time. |

 | | Sneaky: <How on Earth did advice from Lasker become "the Fischer motto"?> Don't be hard on him, it's easy to get all these chess aphorisms confused. The real Fischer motto (of course) is "The pawns are the soul of chess." |
|
| Sep-08-17 | | ChessHigherCat: <Sneaky: The real Fischer motto (of course) is "The pawns are the soul of chess."> And then there's the de-feet-ist motto: "The soles are the feet of chess". |

 | | Phony Benoni: <Sneaky> And I thought it came from Tarrasch: "Sit on your hands!". I have the feeling it may be apocryphal, like all these wry statements. You know how the song goes: "Sing a song of six pence,
Apocryphal and wry." |

 | | Richard Taylor: I thought the theme of a counter and a mate on h8 might happen but I couldn't see anything wrong with Nf5 as the first move. It seemed easily winning from there. But I was wary and searching for a defence for White. I went for the Qxc3+ but taking the R on e1 is stronger but Qxc3+ leads also to a mate. Whiting's method was probably the slowest but also wining.... One of those positions. |
