| Jul-26-11 | | JCRchess: A little-known game, but one of Ildar's masterpieces nonetheless with moves such as 42.)Nf6! & 54.)Bd5+!! requiring precise calculation. If 56.)... Rd7, White wins quickly with 57.)g7+! |
|
| May-26-21 | | Walter Glattke: A) 54.Nf6+!? Kf7 55.Bd5+ Kf8 / 54.-Kg7 55.Bd5 Nxf5 or 55.Re7+ Kf8 helpmate for problem chess compositions with 1.Nf6+ Kf7 2.Bd5+ Kg7 3.Re7+ Kf8 4.Rf7#
B) 54.Bd5+ Kg7 55.Re7+ Kh8 56.Nf6 Nxf5 57.Rh8# "Arabic mate".
C) 54. Bd5+ Kxh7 56.Re7+ Kh8 57.g6 Nxg6 58.fxg6 Rf8+ 59.Kg3 Rf3+ 60.Kf4 Bd7+ 61.Kxf3 Bg4+ 62. Kxg4 mate next
D) 54.Bd5+ Kh8 55.Nf6 Nxf5 56.Rh1+Kg7 57.Rh7+ Kf8 58.Rf7# |

 | | An Englishman: Good Evening: The puzzle's OK, however, the impressive part of the game starts after 11...Nf6, a position not just equal but sterile. White did a terrific job of keeping the game alive and finding ways to improve his position. |

 | | al wazir: Rats. I saw the right continuation, but not the coup de grace: 56...Nxg6
57. fxg6 Rd7 58. g7+, and white promotes next. |
|
| May-26-21 | | nalinw: According to the machine the biggest mistake by Black was not going after the pawns but 52..... Nh4 - 52. .... Ne5 is what the machine would play |
|
| May-26-21 | | WorstPlayerEver: I had 55. Rh1, so I'm on par with Chigorin. |
|
| May-26-21 | | Granny O Doul: 43...Kg7 must be a typo for ...Kf7. |
|
| May-26-21 | | Brenin: After 54 Bd5+, Black is not forced to take the N with 54 ... Kxh7. What about 54 ... Kh8, e.g. 55 Re7 Nxf5 ? Is 55 Rh1 better? |
|
| May-26-21 | | agb2002: White is two pawns down.
Black threatens Kxh7, Nxf5 and Nxf3.
The position of the black king suggests 54.Bd5+: A) 54... Kxh7 55.Re7+ Kh8 56.g6
A.1) 56... Re7 57.g7+ Kh6 58.g8=Q+ wins.
A.2) 56... Nxg6 57.fxg6 Rf8+ 58.Kg3 wins.
B) 54... Kg7 55.Re7+ Kh8 56.Nf6 and mate in two. C) 54... Kh8 55.Rh1
C.1) 55... Kxh7 56.Rxh4+ Kg7 57.Rh6 Rf8 (57... Kf8 58.f6 Ke8 59.Be6 and 60.Rh8#) 58.f6+ Rxf6 (58... Kf8 59.Rh8#) 59.Rxf6 wins decisive material. C.2) 55... Nxf5 56.Nf8+ Kg7 57.Ne6+ wins decisive material. |

took the white Knight it was mate in 8.

 | | halito27: <agb2002> C.2) "55... Nxf5 56.Nf8+ Kg7 57.Ne6+ wins decisive material." This endgame is actually pretty hard to win: black's going to have four connected pawns in exchange for the rook. White should be better, but knight + rook vs. knight + 4 pawns is not an automatic win. Regardless, 54...Kh8 clearly the best line for Black. |

Is 55 Rh1 better?> I looked at that last night and every line I could come up with resulted in either a loss of the black rook, a pawn promotion or checkmate in the corner. |

| May-26-21 | | TheaN: The moment I eventually did spot <54.Bd5+ Kxh7 55. Re7+ Kh8 56.g6 +-> I kind of forgot that 54....Kh8 is a serious alternative. White needs 55.Rh1! else the combo still fails. I had seen this in combinations involving an early Nf6 (which don't work) but forgot to analyze it now. Mainly 55....Kxh7 56.Rxh4+ Kg7 57.Rh6! +- and 55....Nf5 56.Nf8+ Kg7 57.Ne6+. I hadn't checked this so semi solve. |
|
| May-26-21 | | saturn2: I wanted to trap the Nh4. Black can escape this but at a high price. At least thats what I thought.
54. Nf6+ (saving the own knight with tempo) Kg7 55. Bg4 (against Nxf3 and Nxf5) 55...Bd3 (Rh8 56.Re7 seemed no better) and so on for example 56. Nh5+ Kf7 57. f6 Nf5 58. Bxf5 Bxf5 59. Re7+ Kg6 60. f7 Bd7 |
|
| May-26-21 | | Refused: 54.Bd5+! Kxh7. 55.Re7+ Kh8
here my first impulse was to discard the line, untill I realzied that black has no adequate defense against 56.g6!! Cute little combo. |

This endgame is actually pretty hard to win: black's going to have four connected pawns in exchange for the rook. White should be better, but knight + rook vs. knight + 4 pawns is not an automatic win.>The problem is that after 57... Kg6 58.Nxd8 Kxg5 White loses its last pawn. I've just checked this line with DroidFish and it found the problem-like move 58.Bf3, with the threat Bh5+ and mate in two, which allows White to keep the pawn and still win the rook. For example, 58... Ne7 59.Be4+ Nf5 60.Rh6+ Kf7 61.Nxd8+ Ke7 62.Bxf5 wins easily. |
|
| May-26-21 | | agb2002: <halito27> Thank you for pointing out this detail. I've just noticed that <mel gibson> already posted this line with 58.Bf3. |
|
| May-26-21 | | Ivan Karamazov: <agb2002: 54.Bd5+ ...... C) 54... Kh8 55.Rh1 ........ C.2) 55... Nxf5 56.Nf8+ Kg7 57.Ne6+ wins decisive material.> This is true, but the position is still not as easy as one might think: 57...Kg6; 58.Nxd8 Kxg5. Note Black almost has material equality (4P vs. R). Yes, White can win a pawn with 59.Rh7 but Black gives the a-pawn, not the far more valuable b-pawn, by playing 59...Be8; 60.Rxa7 b5, and the resulting endgame is still indeed winning for White, but the process is long, tedious, and surprisingly easy to botch. However Six-Second-Stockfish comes to the rescue with the beautiful 58.Bf3!! (instead of 58.Nxd8(?)) which threatens mate in 3, forcing 58...Kf7; 59.Nxd8 and White has kept his g-pawn. |

| May-26-21 | | Ivan Karamazov: When I posted, the automatic chess-proverb-generator kicked out <A player surprised is half beaten.> i-dunno-bout-that. Most of my experience is more along the lines of "I'm surprised you would play something that stupid." |

 | | eternaloptimist: I solved this puzzle really quickly b/c I saw how the black ♔ was susceptible to being bottled up in the corner. I agree w/ <An Englishman> when he said Ibragimov <did a terrific job of keeping the game alive and finding ways to improve his position.<>> Although he did play some bad moves. I actually saw Ibragimov at a tournament in Denver way back in ‘03 (as mentioned in my profile). In between rounds I saw him outside & I was going to talk to him for a while. Although after I said something to him, he looked at me, didn’t say anything & turned back around. I thought to myself that he probably doesn’t speak much English. 🤷🏻♂️ In his profile it says that he moved to the US in ‘02 so it would make sense that he didn’t speak much English & could only speak Russian fluently. Back then he probably had some Russian players who could speak both languages fluently translate for him but I’m willing to bet now he speaks English well. He lives in New Haven, Connecticut so I’m willing to bet that Sergey Kudrin translated for him since he has also lived in Connecticut for a long time & btw still lives there. Kudrin was also at the tournament that I mentioned above & he & Ibragimov finished tied for 5th -> 10th in the open section. I have a link that shows the final standings for all of the players that played in it in my profile.
<agb2002> So u use DroidFish. So do I on my tablet! It’s the android version of Stockfish for those of u that aren’t familiar w/ it. I like it a lot! |

| May-28-21 | | agb2002: <eternaloptimist:...
<agb2002> So u use DroidFish>It's some kind of love-hate relationship.
On the one hand, this little tool is very useful to understand some important details when I couldn't decide on the evaluation of the final position of a line and ended up settling for a rather frustrating 'unclear'. On the other hand, it reminds me of Nelson Muntz, The Simpson's HA HA boy, every time it shows some of my moves are clearly suboptimal or even embarrassing blunders. In these cases I feel very tempted to uninstall it. Then, another 'unclear' line appears... |
