| Jan-27-21 | | Ivan Karamazov: i doubt that this is a suitable Wednesday puzzle - after the far superior 28...fxg6, the machine says White has a clear winning edge <+2.20 (22 ply) 29.♗xf8 ♗xf8 30.♕xg6+ ♗g7 31.♘e4 ♕d8 32.♘f6+ ♕xf6 33.♕xe8+> but there's still a lot of work needed to prove it. <cg>, please stop feeding us puzzles where the seeming smooth elegance of the solution depends on the defense making a bad mistake. either that, or at least change the note on the front page to "see game page discussion for solution" |

 | | Dionysius1: I didn't solve it, but that's a lovely move. The less I worry about the competitiveness/self improvement aspects of chess, the more I enjoy it. |
|
| Jan-27-21 | | Transfinite Cardinal: Tough but I got it! Was on the point of giving up. |
|
| Jan-27-21 | | awfulhangover: I gave up, and felt stupid after I saw the solution. Black must have been shocked after 28. Ne6!! |
|
| Jan-27-21 | | TheaN: I did note White's only shot was <28.Ne6!>, but couldn't make all variations work; and rightfully so, because this is not a Wednesday, tbh. Yes, after 28....Nxe6? (or 'any other' move Qg7#) 29.Bf6 Bh2+ 30.Kh1 with Qh8#. <However>. <28....fxe6> is critical, simple. The other alternative is worth a mention too, 28....Be5 blocking access to f6, 29.d6! (though 29.Bxf8 fxe6 30.d6! might be easier, same idea) is deal breaking as the Black queen is taken out of the defense. After 29....Nxe6 30.Rxe5 Rxe7 31.dxe7 +- and Re5 is immune due to e8. <29.Bxf8! Bxf8 30.Qxg6+ Bg7 31.Ne4! Qd8 32.Nf6+ Qxf6 33.Qxe8+ ±> is almost as tough to spot. My conclusion, main line's easy, side lines aren't Wednesday lines. |
|
| Jan-27-21 | | Viking707: I thought the solution was Qh8+, forcing KxQ, followed by Bf6#. Is this refutable? |
|
| Jan-27-21 | | Refused: 28.Ne6! is a nice tactic indeed.
a)28...Nxe6 29.Bf6 is obviously curtains
b)28...fxe6 29.Bxf8 Bxf8 30.Qxg6+ Bg7 is obviously much better for white, but not a clear k.o. punch |
|
| Jan-27-21 | | njchess: Tough Wednesday puzzle. I managed to get it, but it took a loooong time. I only managed to find 28. ♘e6 because I couldn't find another forcing move. I even entertained notions of sacing the White Queen! Black would have been better to recapture with the pawn than the game line, but White still has a significant advantage. |

| Jan-27-21 | | R4f43l L3 M4550n: Though one! Maybe a friday puzzle... Well, my Nce4 doesn't worked... |

Look one more time you will find the answer yourself. Hint: The king has one legal move left after Bf6+ |

|
| Jan-27-21 | | beugi19: Nothing to add, got Ne6 and the answers to Nxe6 and Ne5 right, missed the Re7 defense. Plus, this is the only Korobov game from this event in the database, weird... or is there some mistake? |
|
| Jan-27-21 | | Lambda: I think anyone who sees 28...fxe6 29. Bf6 Re7 with the idea of K-f7-e8 should give themselves full Wednesday-level credit. |
|
| Jan-27-21 | | DrGridlock: On my first glance, I noticed that Bxf8 threatens mate on g7 and on h7, and that black cannot prevent both ... except by mating himself with Rxe1. So how to "jam up" the e-file to give white's threats the tempo they need? Ne6 seems to meet that need, and ... Nxe6 leads to a quick mate by White. What happens in the exf6 lines? I looked at Bxf8 Rxf8 and concluded that White's attack was overwhelming (which it is). I missed that Black has TWO ways to capture the intruding bishop on f8 (Bxf8). It turns out that White does have enough in that line: Qxg6 Bg7; Ne4! Re7; Nf6+Kf8 and white is winning (+2.56 computer eval), though that line is tricky because White is still a piece down and won't pick it back up for another couple moves, and in one line: Rxe6 Qd8; Qh7 Kf7; Nh5 Qxd5; Qxg7 Kxe6 Anton Korobov - Ajgaonkar Mithil 1-0, 25th Abu Dhabi International Chess Fest 2018

| Jan-27-21 | | AlicesKnight: Yay - found it. A pretty self-interference created. |
|
| Jan-27-21 | | Halldor: I saw that Bf6 would lead to mate if Black couldn't play RxR# So I wondered if the e-file could be blocked somehow. That immediately led me to the text move 28 Ne6!! |
|
| Jan-27-21 | | agb2002: White has a bishop and a knight for the bishop pair. Black threatens Rxe7.
28.Bf6 and 28.Bxd6 (with the idea 28... Qxd6 29.Qh8+ Kxh8 30.Nxf7+ and 31.Nxd6) are not possible due to 28... Rxe1#. This suggests 28.Ne6 (28.Re6, with the triple threat Bf6, Bxd6, Nce4, and 28.Re3 are met with 28... Bxe7): A) 28... fxe6 29.Bf6 Qc7 30.Qh8+ Kf7 31.Qg7#.
B) 28... Nxe6 29.Bf6 wins.
C) 28... Be5 29.Bxf8 (threatens Bg7) 29... fxe6 30.Qxg6+ C.1) 30... Kxf8 31.dxe6 Qc7 (or 31... Re7; 31... Ke7 32.Qf7+ and mate next) 32.Qf5+ wins two pawns at least. C.2) 30... Kh8 31.Bh6 (threatens Rxe5) 31... exd5 32.Bf4 Re7 33.Bxe5+ Rxe5 34.Qf6+ wins decisive material. |

 | | gawain: It's a pretty combination but Black sure did pick the wrong way of capturing the knight. 28...Nxe6 is disastrous! White has the edge (but only an edge) after 28... fxe6 |
|
| Jan-27-21 | | DrGridlock: <agb2002>
28 ... fxe6 is the critical line for black.
Qc7 (after Bf6) in your line does lead to mate.
Which is why black will probably respond with the more problematic Re7 (now after Qh8+ Kf7; Qg7+ the black king has an escape square on e8). Still a bit of analytical work to do to find the advantage / win for White. |
|
| Jan-27-21 | | agb2002: For some reason, I thought that 29... Re7 was not possible in my line A (perhaps I still had Be5 in mind) but Whire's attack seems to vanish. Instead of 29.Bf6, 29.Bxf8, similar to C, is enough to win. |
|
Jan-27-21
 | | steinitzfan: I saw that Bxf8 would be devastating if not for the weak back rank and then I reasoned that the knight is needed where it is to support the mate. So I made the interference move Re6??? - a glorious fail.
The variations where Black captures the rook are very pretty though. |
|
| Jan-27-21 | | Everett: Lol I would have self-mated in one.
My only excuse is because I got parachuted into the position |
|
| Sep-06-21 | | R4f43l L3 M4550n: As revisiting this game I see it more clearly now. White has managed a strong mobilization in blacks´s castle, fragilizing it. But placing the Knight at f8 (27... Nf8), Black as first glance seens to hold the position well - defending checkmate threats and intend to grab the white e7 Bishop. In other words, 27... Nf8, is a multi pourpose move. So not only 28.Ne6 is a attacking manouvring but a forced one. Analysing thru enterily game, and not the puzzle move, my perseption has increased. |
