| Jul-15-05 | | vonKrolock: The match USA vs Czechoslovakia in the last round of the Folkestone 1933 Ol was decisive for the order in the honour places: the Americans should score just one point from the four at stake to convert the leadership in final lone victory - while for the czechoslovakians only a victory by 3 1/2 to 1/2 would turn the second place to triumph - no tie was possible, and none of the other teams could join in the top... (Poland 4-0 against Iceland was enough just to share 3th place with Sweden and Hungary) Flohr played in bravourous mood, retaining the black King in the centre with a Pawn giving followed by an exchange sacrifice - the decisive phase shows signs of nervousness and time shortage <28.♖d8?? ♔c7??>: when the dust went down, Flohr had performed his duty, as Opocensky in the 4th board against Simonson; Rejfir detained Fine to a drawn Game in the 3th board, so it was the veteran Marshall who saved the day beating Treybal in the 2nd board... |
|
| Jun-09-07 | | sfm: It goes with this story that incredibly nobody discovered the mentioned blunders. Neither the players, nor the commentators, who all accepted the forced win for white.
An amateur player then wrote in to the Danish "Skakbladet" ("The Chess Magazine") with his own analysis of 28.Td8+,Bc8. |
|
| Jun-10-07 | | vonKrolock: <28.♖d8?? ♔c7??> The double blunder was pointed out by Árpád Földeák, in "12 Sakkolimpia (London 1927-Moszkva 1956)", hungarian book from 1958. |

| Jun-11-11 | | sfm: <vonLrolock: The double blunder was pointed out [in a] hungarian book from 1958.>
OK - the game is from '33 - hopefully the danish guy I mentioned took less than 25 years to write to "Skakbladet" :-) |

| Jun-11-11 | | sfm: Thanks, BTW, for the interesting info. |

 | | FSR: No one spells it out, but I take it the point is that 28.Rd8+?? would have left White's back rank hanging after 28...Bc8!, threatening 29...Qa1+, 29...Qb1+, and 29...Qxf2+. |
|
| Jul-01-11 | | supastarr: it does look like both missed Bc8, but 29 Qe5+ Ka8 30 Rxc8+ Rxc8 31 f4 looks strong (winning?) for white |
|
| Nov-30-13 | | Patriot: White is down a pawn. Black threatens 16...Bxg5, 16...Qxc3, and maybe 16...Nb6. The queen looks to be losing some mobility after 16.Be3. I see a few captures, 16.Bxe7 and 16.Rxd7. 16.Bxe7 Kxe7 doesn't look like much.
16.Rxd7 Kxd7 17.Rd1+ Ke8 seems to lose steam.
16.Rxd7 Kxd7 17.Qd1+ Ke8 doesn't make sense.
16.Rxd7 Kxd7 17.Qd4+ Qxd4 18.Nxd4 - strange.
16.Rxd7 Kxd7 17.Be3 Qh5 and I would love to get 18.Ne5+ in but 18...Qxe5 spoils everything. I'm just now seeing how this is possible.
16.Be3 Qh5 17.Nd4 hitting the queen and c6.
Probably best is 16...Qxc3.
16.Be3 Qxc3 17.Rac1 Qf6 18.Bg5 Qg6 19.Rxd7 Kxd7 20.Ne5+  16.Be3 Qxc3 17.Rac1 Qf6 18.Bg5 Qf5 19.g4
I think 16.Be3 is best. I'm not seeing any other threats that lead to anything. 16.Rb1 Bxg5 17.Rxd7 or 17.Rxb7 just doesn't seem right. 16.Be3 is a no cost way to put pressure on. Another idea is 16.Be3 Nb6 17.Qg4 Qxc3 18.Bd4 looks menacing. I spent way too much time on this so it's time to see what happened. |
|
| Nov-30-13 | | Patriot: This one is way beyond me. I looked at the same line up to 17.Be3 and after that there are other squares such as f5 and h5 but white could go with 18.Nd4 I suppose to pressure c6. I will really have to look at this further. |

 | | Benzol: IIRC the position in this game position turned up in Alexander Kotov 's book "Think Like A Grandmaster". Seeing the position years ago I wasn't able to work out what the best move was at that time. |
|
| Nov-30-13 | | Akshay999: Not sure if Kashdan in his lifetime ever realised he missed Bc8 |
|
| Nov-30-13 | | diagonalley: 16. RxN is an obvious candidate, but i'm ashamed to admit i got no further :-( |

this looks more forcing leading to 2B+N+P for R+B after 25.Qxa7 or Bxa7 |

PM: While 16.Rxd7 appears to be the best candidate, the critical move is therefore move 17 when White has 17.Rb1 or 17.Be3 as in the game ***** |

Nov-30-13
| | FSR: After Flohr's blunder <28.Rd8+?? Bc8!> (instead of 28...Kc7??), White would have had to lose an exchange with <29.Qe5+ Ka8 30.Rxc8+ Rxc8> and now Houdini 3 gives as best <31.g3> (31.f4?! exposes White's king after 31...Qb1+ 32.Kf2 Rb8) <31...Rf8 32.Qd4 Qb3 33.h4 Qb4 34.Kg2 a5 35.Qd7 Qc5> and Black is better (-0.41). |
|
| Nov-30-13 | | morfishine: <Patriot> Yes, a quite involved position; its hard to identify a clear theme other than keeping the position fluid <FSR> Nice post
***** |
|
| Nov-30-13 | | lost in space: Well, I saw the first few half moves but I was far away from solving this puzzle and I doubt I would have played Rxd7 OTB |

| Nov-30-13 | | abuzic: <morfishine: I was "Floored" when black "Cashed-in" (1) 16.Rxd7 Kxd7 17.Rb1 Rhb8 18.Be3 Qa3 19.Rxb7+ Rxb7 20.Ne5+ Kd6> (Best is 20...Ke8), cause now it's mate in 3: 21.Qd4+ Kc7 22.Qd7+ Kb8 23.Nxc6# And in your line
<21.Qxc6+ Kxe5 22.Bd4+ Kf5 23.Bd3+ Kg5> this is forced mate after 24.Be3+ Kf6 25.Qf3+ Ke5 26.Bf4+ Kf6 27.Bd6+ Kg5 28.Qf4+ Kh5 29.g4+ Kh4 30.Qg3+ Kg5 31.Bf4+ Kf6 32.g5#) Even faster would be 23.Qf3+ Kg5 24.h4+ Kxh4 25.Qg3#. |
|
| Nov-30-13 | | gofer: This position is mostly about the loose Bb7 and an uncastled king defending Nd7, but
thae addition of having a queen that can be battered about the board while while
re-organises his pieces into a strong attack is the icing on the cake... <16 Rxd7+ Kxd7+>
<17 Be3 ...>
Before launching an attack on Kd7 (via Pc6) white puts the queen in a bad position and
brings more minor pieces to bare on the king...
17 ... Qxc3 18 Rb1 (offering either Bd4! winning the queen or Rxb7+ ) 17 ... Qf5 18 Nd4 Qe5/Qf6/Qg6/Qc5 19 Rd1
17 ... Qh5 18 Nd4 Qe5/Qg6/Qc5 19 Rd1
~~~
Completely missed the main line... ...Hmmm. |

 | | Penguincw: I got the pretty obvious 16.Rxd7 Kxd7, but didn't see how 17.Ne5+ would be a good follow... |

| Nov-30-13 | | BOSTER: <Patriot I think 16.B e3 is the best>. After this black can play Nb6 17.Qq4 Qf5 18.

Another game between the same opponents played in Hamburg three years earlier (Kashdan vs Flohr, 1930) featured a textbook endgame in which Black (with RP on 7th supported by its King) still loses against Queen plus King (no pawns) due to strong position of White’s K. |

I don't know--there are so many ideas it's hard to say but it doesn't end there. |
