"The crowded hall is flooded with light. The pieces on the demonstration board move slowly. A murmur runs though the hall as a game becomes more and more tense as new threats arise and are effectively refuted. The gaze of the spectators is drawn time and time again to the game where one attack follows another in swift succession, where unexpected manoeuvres lead to unusual and involved positions. That game is being played by Grandmaster Geller." Kotov and Yudovich in 'The Soviet School of Chess.' |

Sep-19-18 | | Strelets: Excellent tribute by Kotov to the player who did this to him in the same Soviet championship as this semifinal: Kotov vs Geller, 1949, |

 | | Sally Simpson: Hi Strelets,
"I sometimes wonder what might have happened had Geller won at CuraƧao 1962." I think we would still have got 'The Russians Have Fixed World Chess.' http://www.chesshistory.com/winter/... (from Edward Winters Chess Notes 10956)
I also think Botvinnik would have beaten Geller. Botvinnik had learned in his matches v Tal how to rob imaginative players of the unbalanced positions they tended to thrive on. Maybe age would have told in favour of Geller who would no doubt have scored a few stunning victories but he was also lovingly erratic. It would have been interesting. |
|
Sep-19-18 | | saturn2: <but he was also lovingly erratic>
Maybe because he started chess relatively late in his life. I saw a picture of him from 1953 - a time when he was called the Russian Morphy. In 1984 me being a teenager played simultan against him. He had a big stomach then which surprised me since I had ecpected the ascetic man from the pic with the Morphy like glance.
He won almost all games and lost none. He would get angry when someone did not observe the touch move rule. |

Sep-19-18 | | cormier: patzer2: <you had it already> P.S.: So where does White go wrong? White's game takes a big turn for the worse after 28. a5? Qh5 ∓ to -+ (-1,80 @ 30 ply, Stockfish 9). Instead, 28. Bh3 Nhf6 29. Kg2 Ra8 30. Bd2 Bxa4 31. Nxa4 Rxa4 32. Nc3 = (-0.08 @ 36 ply, Stockfish 9) holds it level. |

 | | Sally Simpson: Hi saturn2,
Deep pure jealous you got to play him.
Simul masters and their rules differ.
Shamkovich allowed one pass, Aagaard as many as you like (I got a draw in both). On one occasion I was reading about in CHESS a famous British G.M. insisted you move the moment he appeared at board, if not he would push pieces off the board. Game Over. First fell for Geller when this game slip over my board in the 70's. Geller vs Kogan, 1946 '...lovingly erratic'
see Flohr vs Geller, 1957 where I have just added a post. |

Jun-09-22 | | Brenin: Another recycled POTD, this one from before my time on CG. I liked the look of 33 ... Be3+ 34 Rxe3 (otherwise 34 ... Rxa7 and 35 ... Ra1+) Qh2+ 35 Kf1 Nxe3+ 36 Kf2 Nxg2 37 Qb7 Rf8+ 38 Nf4 Nxf4+, but 37 Qxd6 gives White a draw. Better was the quiet but lethal 34 ... Rf8, e.g. 35 Nf4 Qh2+ 36 Kf1 Nxe3+, with a clear win. |
|
Jun-09-22 | | GufeldsVengeance: It is so "medium" that Geller didn't get the right answer. The people who come up with the rankings are a joke. The answer is ..Be3, Rxe3, Rf8...
Not "medium" Not even close. |

Jun-09-22 | | mel gibson: A recycled puzzle which I analysed on Sep-19-2018. I redid this puzzle -
this time with Stockfish 15 and more time
on my more powerful 8 core computer.
Why did White resign?

34...Rf8 35. Rf3 Qh2+ 36. Kf1 Rxf3+ 37. Bxf3 Ne3+ 38. Ke1 |
|
Jun-09-22 | | saturn2: <Jimfromprovidence: FWIW, in the 34...Rf8 option white also has 35 Rf3 as a defense.
It's kind of an interesting sub-line, because now black has to see that 35...Rxf3, allowing white's a pawn to promote with check by 36 a8Q+, below, does white no good. BTW in the top diagram, 35...Qh2+ is losing for black.> As far as I see 35...Qh2 is winning for black.
36.Qh2 Kf1 37.Rxf3 Bxf3 38.Qf2. No? |

 | | Stonehenge: <White in this game is Tadeusz Lubienski>. Probably fake news. The Ukrainian player M Lubensky is far more likely. |
|
Jun-09-22 | | Brenin: <sorso>: 33 ... Be3+ 34 Rxe3 Rf8 35 Rf3 Rxf3 wins for Black, e.g. 36 Bxf3 Qh2+ 37 Kf1 Qf2 mate, or 36 a8=Q+ Kh7 and a similar mate is inevitable. |

Jun-09-22 | | parch: 33...Be3+ 34.R:e3 Rf8 35.Nf4 Qh2+ 36.Kf1 N:e3+ 37.Ke2 ef4 Looks good for Black. Have not looked at the 34....Qh2+ option.
nor the 34...Rf8 35.Rf3 |
|
Jun-09-22 | | Cellist: I also liked 34. ... Rf8 and thought this was easily winning (which is right if B finds the correct follow-up). I did not see, however, that 35. Rf3 (which I correctly discarded as weaker than 35. Nf4) has to be answered by Rxf3 and not Qh2+. |

Jun-09-22 | | TheaN: Hm. Tricky Thursday. Given this was used as a Wednesday before, and it's now clear Geller erred in the finish, perhaps a bit too tricky. I too was drawn too much to the game line, <33....Be3+> only pressuring move <34.Rxe3!> else Rxa7 and a clearly lost game as White lost all leverage. <34....Qh2+?!>

It makes so much sense, it's almost weird it's not the best move. Black postponed Nxe3 to create a tempo, yet 35.Kf1 Nxe3+ 36.Kf2 Ng4+; kind of an important point here that 36....Qxg2+ 37.Ke3 +- doesn't lead to anything, 37.Kf1 Rf8+ (which now comes too late) 38.Ke1:

After 38....Qxg2 ∓ Black's better, but White ends up using his asset on the a-file. After <34....Rf8!>:
 click for larger view
Black plays the rook away early, and now it threatens Qh2#, so White has no time to play the a-pawn. That's key: White loses a move to prevent the mate, in comes out much worse in all variations. The two key lines are 35.Rf3? Rxf3!! as now the mate's unavoidable, so the a-pawn doesn't even matter. 36.a8Q+ Kh7 37.Qh8+ Kxh8 38.Qa8+ Kh7 39.Qh8+ Kxh8 40.Bxf3 Qh2+ 41.Kf1 Qf2#. Instead, <35.Nf4> gives Black the extra move that White didn't want to concede: <35....Qh2+ 36.Kf1 Nxe3+ 37.Ke2 exf4 -+> and again a8 doesn't really matter, as Black's now up a rook and will win an additional piece. |

Oct-12-22 | | mayankk06: Such an interesting double blunder. Shows how everyone is so human without an engine, and superman with one. My first instinct was also that 33 ... Bxe3 34 Rxe3 Qh2+ 35 Kf1 Nxe3+ forking King and Bishop, and followed by Rf8 at some point, is just too much for the White King to handle. Only when I went through the comments again did I realise that the right continuation was 33 ... Bxe3 34 Rxe3 Rf8! allowing the 34 ... Nf4, 34 ... Rf3 defences as well as a8+ Queening later. Very instructive. |
