| Aug-18-14 | | JimNorCal: Black's position looks fine to me around move 25 but he overreaches and Bernstein pulls off a short, brutal and completely effective counter attack. Thanks for your notes and for posting this interesting struggle. |
|
| Jan-19-22 | | landshark: This one came more easily than yesterday's - possibly because the 38.Rh7+ idea is screaming to be looked at.
Then it's a matter of figuring out how to work around the black Q and the f7 pawn's coverage of g6 - which 39.Ne5+ neatly sets up. |
|
| Jan-19-22 | | mel gibson: I saw the first ply straight away then spent
another 20 seconds confirming it was the best move.Stockfish 14 says mate in 5:
38. Rh7+
(38. Rh7+ (♖h1-h7+ ♔g7xh7 ♘g6-e5+ ♔h7-h6 ♕f5-h5+ ♔h6-g7 ♕h5xf7+
♔g7-h8 ♘e5-g6+) +M5/245 5) |
|
| Jan-19-22 | | Brenin: 38 Rh7+ Kxh7 (otherwise 39 Qxf7 mate) 39 Ne5+ cutting the Black Q off from defence of her K), e.g. 39 ... Kh6 40 Qh5+ Kg8 41 Qxf7+ Kh8 42 Ng6 mate, or 41 ... Kh6 42 Qg6 mate. Alternatives 39 ... Kg7, Kg8 and Kh8 end similarly. |
|
| Jan-19-22 | | TheaN: For this Wednesday, White creates a fatal discovered check by casually throwing a rook at the king. Educational nonetheless. <38.Rh7+> no real declining possible here, all alternatives lead to 39.Qxf7# <38....Kxh7 39.Ne5+! #3> is key, as it keeps tabs on f7 and g6, which are the crucial squares in this Q+N mating net. Eventually the queen's going to f7 and then either piece to g6. For good measure, here are the principle two lines (to the g- or h-file), writing all moves is a bit unnecessary. 1) 39....Kg7 (Kg8) 40.Qxf7+ (Kh6 41.Qg6#) Kh8 41.Ng6# 2) 39....Kh8 (Kh6) 40.Qh5+ Kg7 (Kg8) 41.Qxf7+ Kh8 (Kh6 42.Qg6#) 42.Ng6# |
|
| Jan-19-22 | | Brenin: The combination actually starts with the clever 36 Ne7+, forcing either 36 ... Kf8 as in the game (since 36 .. Rxe7 37 Qc8+ Kg7 38 Qh8 is mate) or 36 ... Kg7 37 Qxe4 Qf6 38 Nd5 Qxf2+ 39 Kxf2 Rxe4 40 Nxb6 axb6 41 Kf3 with an easy win for White. That would make a good Saturday or Sunday POTD. |
|
| Jan-19-22 | | Refused: 1.Rh7+ Kxh7 2.Ne5+ and black gets mated; the point is that White will eventually play Qxf7+ (the check is important). After that black gets mated on g6, either with Qg6# or with Ng6#. Relatively easy and straight forward puzzle with no sidelines to consider. |
|
| Jan-19-22 | | BxChess: I chose a different order: 38 Ne5 Nd6 (forced) 39. Rh7+ Kg8 40. Rxf7 with mate to follow |
|
| Jan-19-22 | | Whitehat1963: Could not find the right square for the knight. (Did not search long enough.) |
|
| Jan-19-22 | | mel gibson: <Jan-19-22 BxChess: I chose a different order: 38 Ne5 Nd6 (forced) 39. Rh7+ Kg8 40. Rxf7 with mate to follow> That doesn't work.
38 Ne5 Qxf2+ leads to a draw. |
|
| Jan-19-22 | | FM David H. Levin: <Brenin: 36 Ne7+, forcing either [snip] or 36 ... Kg7 37 Qxe4 Qf6 38 Nd5 Qxf2+ 39 Kxf2 Rxe4 40 Nxb6 axb6 41 Kf3 with an easy win for White.> It might be worth adding that 38...Qxf2+ was given because 38...Rxe4 fails to 39 Rh7+! followed by 40 Nxf6 (with or without check). |
|
| Jan-19-22 | | stacase: Black's Queen wants to move f2+ supported by an annoying Knight, she also covers h8 which is a problem. White needs to say check all the way to mate, or somehow remove Black's obnoxious knight. Ah, a Rook sacrifice allows White's Knight to pull off a discovered check while blocking the Black Queen's access to h8. And then it all works. I would have moved 40.Qf4+ instead of 40.Qh5+ because it preserves the option of taking Black's Knight and still forces 40...Kg7 or Kh7 followed by 41Qxf7+ and mate soon after. In other words I missed the shorter forced mate. |
|
| Jan-19-22 | | saturn2: 38.Rxh7 and then 39.Ne5+ Other checks like 39.Qxf7+ or 39.Qh5+ had to be falsified. |
|
| Jan-19-22 | | saturn2: 35....g6 weakened the king.
35....Nf6 and black can play on. |
|
| Jan-19-22 | | saturn2: already observed 2014 and 1907:) |
|
| Jan-19-22 | | agb2002: White has a knight and a pawn for a bishop.
Black threatens Qxf2+, simplifying the game and recovering the pawn. White can deliver mate with 38.Rh7+ Kxh7 (38... Kg8 39.Qxf7#) 39.Ne5+: A) 39... Kg8 40.Qxf7+ Kh8 41.Ng6#.
B) 39... Kg7 40.Qxf7+ Kh6 (40... Kh8 41.Ng6#) 41.Qg6#. C) 39... Kh6 40.Qh5+ transposes to B.
D) 39... Kh8 40.Qh5+ transposes to A or B. |

 | | Teyss: <Brenin: The combination actually starts with the clever 36 Ne7+> Yes. However the puzzle line does not work as I first thought: 36...Kg7 37.Rh7+? Kxh7 38.Qxf7+ Qg7 (not Kh8?? or Kh6??) and Black wins. In the puzzle 39.Ne5+ blocks the diagonal. |
|
| Jan-19-22 | | AlicesKnight: Found the R check and Ne5+ way in. A need to be precise to avoid a rescue by the Black Q. |
|
| Jan-19-22 | | Refused: <Teyss: <Brenin: The combination actually starts with the clever 36 Ne7+> Yes. However the puzzle line does not work as I first thought: 36...Kg7 37.Rh7+? Kxh7 38.Qxf7+ Qg7 (not Kh8?? or Kh6??) and Black wins. In the puzzle 39.Ne5+ blocks the diagonal.> There the rather prosaic 37.Qxe4 is the end of the line for black, as there's no way to regain the lost piece (now 38.Nf5+ is a real problem) Black's worries start earlier. My first thought was to critizise black for 34...Ne4 and thus allowng white to play 35.Qf5, after which there's no escape (at least I don't see one), 34...Qc2 seems to be a better attempt to stay alive (the idea is to get the queens of the board with Qe4). But even there black is in trouble after 35.Qh3 f6 (more or less forced). The position is super ugly and unpleasent for black, but I think there are no immediate k.o. blows. I wouldn't be surprised if there's a computer line that gives +4 or something. Like I said, it's super ugly and unpleasent for black. |
|
| Jan-19-22 | | GlennOliver: The first-glance move 38. Ne5 loses the necessary tempo given by the R check and ends in a piece exchange and drawn position. |

| Jan-19-22 | | Brenin: <Refused>: Yes, the line 36 ... Kg7 37 Qxe4 is rather prosaic, but the tactics are not quite over. Black can try to capture the pinned N on e7 by attacking it with moves such as Bd8, Qa3, Qf6, Kf8 or Kf6. However, in all cases the N can unpin itself, with a check or an attack on the Q, allowing White to maintain or increase his material advantage, or to deliver mate. As for 34 ... Qc2 35 Qh3 f6 (or possibly 35 ... Qe4+ 35 f3 Qc2+ first), Black's position looks uncomfortable but survivable, with 36 Qh7+ or Qh8+ coming to nothing. |

36...Kg7 37.Qe4 Qa3 arguably has the biggest problem, since the queen is no longer guarding h8. Thus 38.Nf5+ is an immediate mood killer. 38...gxf5 (more or less forced as clever tricks like Kf8 run into Rh8# now) 37...Kf8 38.Nxg6+ looks good enough. fxg6 39.Qxg6 three connected passed pawns on the king side + on going attack against the Black Kings should be the toughest position to convert. 37...Bd8 38.Nf5+ Kf8 39.Qb4+ Kg8 and the Knight is free to hop, whereever it may desire. Side note 39...Kg8 was kinda forced in this line, as 39...Be7(Re7) 40.Nbd4 is a rather fun way to win the queen. |

You're right, thanks for pointing it out. |
