Almost any other move would have been all right, such as 56.c5.> Yes, in time trouble, Korchnoi uncorked 56 ♕d4-h4??, as shown below. Position after 56 ♕d4-h4??:
click for larger viewWhat is the tactical liability of this move? The White h4-queen has <NO RETREAT(!)>. The White h4-queen cannot retreat onto the White side of the board from h4 because its retreat is blocked by the White h3- and f2-pawns. And since the White h4-queen cannot move forward onto the Black side of the board either, the White queen can move -only- laterally along the 4th rank. And so Black (Karpov) ruled out even that possibility with 56 ... ♖e7-e4!, and the White h4-queen is nearly <TRAPPED (NO RETREAT(!))>. Position after 56 ... ♖e7-e4!:
click for larger viewTo meet the threat to the White h4-queen, White must <BLOCK> the 4th rank from the Black e4-rook to his h4-queen with 57 f2-f4 (57 ♘d3-f4?? loses to the <PIN> 57 ... ♗c7x♘f4). Position after 57 f2-f4:
click for larger viewBut as Kasparov points out in his excellent "Predecessors" volume on this game, White could not have picked a worse time to move his White f2-pawn. Why? Because 57 f2-f4, which White had to play to save his queen, left behind the White e3-pawn and now Black simply piles up on this dark-squared and <BLOCKADED> White e3-pawn with 57 ... ♗c7-b6!. Position after 57 ... ♗c7-b6!:
click for larger viewLargely due to the presence of <OPPOSITE-COLORED BISHOPS>, White has no decent way to meet the threat to this dark square e3 and his position collapses! So Korchnoi was just cruising along with the draw in hand when he uncorked 56 ♕d4-h4??. After this blunder he was dead lost, because Karpov was able to combine the tactical ideas <TRAPPED PIECE>, <PIN>, and <OPPOSITE-COLORED BISHOPS> into a winning combination. |

| Apr-09-08 | | Knight13: I prefer Black after 31...Nc4. Before that I just found the Alekhine Gun lined up on d-file by black quite amusing but then letting White play e4 is not amusing... |
|
| Apr-22-08 | | Riverbeast: Instead if 43. d5 (played in time pressure) white should win with the simple 43. Bxc6 |

| Sep-21-11 | | Capabal: The trap was set up by Karpov, counting on Korchnoi's time trouble. In the moves leading to 56. Qh4, Korchnoi had only one and a half minutes on his clock, while Karpov had 40. Karpov was taking his time, hoping Korchnoi would end up playing Qh4 to defend the pawn. In his autobiography, he says: <I had in mind an unassuming trap which I wasn't counting on too much, but I decided to lead my opponent into it; maybe in his haste he'd fall for the bluff. Korchnoi saw that I was planning something and bit into the board as if he could devour it with his eyes. Then I advanced leisurely; he advanced instantly. Again I took my time; he didn’t waste a second of his in response. I gave him the impression that I was attacking a pawn. He sensed something was wrong, but time was running out. He began twitching and defended the pawn with his queen. And right then and there the trap snapped shut: the queen was caught.> (Karpov on Karpov p. 138.) |

| Jun-04-12 | | Kinghunt: This game has the honor of being the only World Championship game where black plays Na8 - and wins! In my database, there are 7490 games where black plays Na8, and white scores 68%. But Karpov shows that he can break all the rules of chess, and still win. |
|
| Jun-04-12 | | Petrosianic: You never actually demonstrated that there was a rule against playing Na8, you only cited a 68% number. |
|
| Jun-05-12 | | Kinghunt: <You never actually demonstrated that there was a rule against playing Na8> I thought it was obvious. <A knight on the rim is dim.> What does that make a knight in the corner? |

2) A Knight in the corner is a loner.
3) A Knight in the corner is a stoner.
4) A Knight in the corner is a mourner.
5) A Knight in the corner is a foreigner. |

of course, it doesn’t help that a horrific blunder was made
which had little to do with the knight.
<Kinghunt:
I thought it was obvious. <A knight on the rim is dim.> What does that make a knight in the corner?> When your knights in the corner, call the Coroner.
If you like rhymes:
<A knight on the rim is dim> but in the corner your chances are slim. |

A Knight on the rim is grim
So you should be nicer to Jim |

| Apr-29-20 | | joddon: 24 rd6 is in my opinion a very amateur decision....having played Fischer through the 60s...Korchnoi had a close chance at winning and almost did, cus by playing good players one becomes good....gave Karpov a lot of trouble throughout every move in this match....but restricting the Queen in a middle game at this point put him back, I think something in the crowd scared him and went downhill from here!!!!!!!!!!!!!!!!!! |
