| Jan-29-13 | | Shams: <FSR> It's funny that you say <"Lest anyone make fun of Iranian chessplayers..."> and then the first game you give shows it happening to...an Iranian chessplayer. |
|
| Jan-29-13 | | Morten: Nice combination out of the blue - or so it must have seemed to black. After 14.-,Qd7 15 Qxd7, Nxd7 16 Nxa6, Rac8 black's pieces are actually much better placed than white's, but of course the extra piece will begin to tell before long. |

 | | FSR: <Shams> Hmm, good point. |
|
| Jan-29-13 | | morfishine: <FSR> I remember both the Jack Peters game (from a long ago CL) & the Stripunsky fiasco. From what I recall, Stripunsky said he mixed up his move order. Alekhine did the same thing when he was in a totally losing position; after a deep think late in the game, he found an amazing drawing combination, only to forget to make the in-between move. I forget this game |

| | FSR: Speaking of absurd material-hangs by high-rated players, check out this line, which incredibly gives White a +1 =1 -1 score in the database: Opening Explorer |
|
| Jan-29-13 | | Abdel Irada: I can only think Black, aware of being a 300-point favorite, played carelessly. With 13. ...Qb6, he'd have pressure to compensate for his pawn. Whether it was *enough* pressure would, of course, determine the soundness of his gambit. |
|
| Jan-29-13 | | morfishine: Only Karpov knows how to properly play the 4...Ba6 Queens Indian (before the barrage of counter-slams arrive, please note there is some sarcasm here...) |
|
| Jan-29-13 | | getnacke: Nc7 is not difficult to find but what is difficult to understand is the rating of the players.. I would have guessed that this was a game between two 1200 players. |

| | FSR: <getnacke: Nc7 is not difficult to find but what is difficult to understand is the rating of the players.. I would have guessed that this was a game between two 1200 players.> Even the strongest players occasionally have brain farts: A Zapata vs Anand, 1988 Christiansen vs Karpov, 1993 Kotov vs Petrosian, 1949 Morozevich vs Korchnoi, 2004 |

| Jan-29-13 | | Once: I suspect that black's spidey sense was not working at the time. Lulled into a false sense of security perhaps. This is the position one move before the POTD:
click for larger viewWhite has just played the seemingly passive 13. Bc1. White's Nc7 doesn't seem to be a threat - it just loses the knight. The Ba6 and Ne4 are both safe. Black's king looks safely tucked away. The e8 square isn't attacked at all. Arguably, we're still in the opening. So what could possibly go wrong with the "normal" developing move of 13...Re8? The position seems safe, quiet, developpy. BTW, "developpy" is a new word for those of us who get confused by the spelling of <manooooover>. There's an O or two and mebbe an E and a U and ... oh, I don't know. Spelling never was my strong suit. Anyhoo, back to the chess. If look a little deeper we see that either white is happy to see us or there is a gun in his pocket. There is a potential discovered attack on the e8 square. This means that in just one move the e8 square could go from being not attacked at all to being twice attacked. And that spells danger, Will Robinson, danger. I guess we've all been there and played a move like 13...Re8 without seeing the risks. The moral of the story seems to be ... think long and hard before standing in the cross-hairs of a discovered attack. |

| Jan-29-13 | | morfishine: Inexplicable GM blunders continued:
Who could forget this one? Saemisch Capa'd off a great tournament with this win: Saemisch vs Capablanca, 1929 |
|
| Jan-29-13 | | whiteshark: <14.Nc7!>, and that's it. |

| Jan-29-13 | | snakebyt: Nc7 or d6 but there are many ways for wht to prevent the QXe8 mate. There is the blk bishop on c1 that could draw the Queen away too. I chose to fork the Rooks. |
|
| Jan-29-13 | | mistreaver: Tuesday.White to play.Easy.14.?
14Nc7! and white wins the exchange.
Time to check

Wow, inexplicable blunder by almost 2600 player.Well everyonce can have a bad day

| Jan-29-13 | | snakebyt: <...many ways for wht to prevent the QXe8 mate.> I meant to write blk. |
|
| Jan-29-13 | | kevin86: White forks both rooks...and the queen can't take on pain of penetration by white's queen. |
|
| Jan-29-13 | | MountainMatt: As usual, I don't have a lot of time here, but thankfully I didn't need a lot - 14. Nc7! jumped out almost instantly. Black can either lose a rook outright or the exchange and a knight. 2-2 |

| | FSR: <morfishine> I hadn't realized how important the brain fart in Saemisch-Capablanca was. Karlsbad (1929) was Nimzowitsch's greatest triumph; he won this super-strong tournament just half a point ahead of Capablanca and Spielmann. So Capablanca's blunder cost him dearly. |
|
| Jan-29-13 | | Kikoman: A knight fork! <Nc7!> :D |
|
| Jan-29-13 | | zb2cr: 14. Nc7! is a terrific move. If 14. ... Qxc7; 15. Qxe8+, Bf8; 16. Qxe4 and White is up by a Rook. Moving the Rook at e8 allows win of a full piece by 15. Nxa6. The attempt at a counterattack with 14. ... Nc3 can be met with 15. Qxe8, Qxe8; 16. Nxe8, Nxd1; 17. Nc7 leaves White up by a full Rook. |
|
| Jan-29-13 | | talsqueen: didnt see it coming. Fantastic move! |

 | | Sneaky: Oh grandmaster, how could you???
It's actually a pretty cute shot. It makes for an easy puzzle knowing that there is zinger, but I could easily imagine missing this over the board. |
|
| Jan-29-13 | | patzer2: <Once> Good observation about 13...Re8? being Black's decisive mistake, allowing the winning "discoverd attack" 14. Nc7! Not sure what Black should have played instead of 13...Re8? I suppose instead of 13...Re8? that 13... Qe7 would be a good alternative, when Fritz suggests play might continue 14.Nd2 Nxd2 15. Bxd2 Bxb2 16. Rb1 Bxb5 17. Qxb5  . However, a fun alternative is 13... c4!? (diagram below, 14. White to move),
