Kibitzer's Corner
Nov-10-07  sitzkrieg: Karpov was winning this game..errors in time trouble again?

Nov-10-07  MarvinTsai: If it were me with time trouble, I would have chosen 34. Rd3. I'm not a GM anyway!
Nov-11-07  scholes: karpov makes the blunder after 40th move ,odd.Don't you get extra time after 40th move in this tournament .41 Rc1 was the blunder.
Nov-11-07  Astardis: Wasn't 35. Rf3 better than the actually played Qf3?
Nov-11-07  Karpova: <scholes: karpov makes the blunder after 40th move ,odd.Don't you get extra time after 40th move in this tournament .> If this was a question the answer is no. Only 120 min from the start with 30 sec per move, nothing more.
Nov-11-07  outsider: i thoroughly like "ANA karpov", the way it is written on the move sheet :)
Nov-12-07  notyetagm: More tactics from Judit Polgar.

Black To Play: 42 ... ?

Here the White e3-queen is tied down to the defense of the <LOOSE> f2-bishop/f2-mating square. Since the White e3-queen is <DEFENDING> f2, she cannot also <DEFEND> e4. Hence Polgar plays 42 ... ♘c5-e4!, exploiting the <OVERWORKED> nature of the White e3-queen.

Position after 42 ... ♘c5-e4!:

Of course this knight is taboo: 43 ♕e3x♘e4?? <deflection from f2> ♕b2x♗f2#.

With 43 ♔f1-g1 White tries to <COUNTERATTACK> against the <UNDEFENDED> Black h2-rook.

Position after 43 ♔f1-g1:

But now Judit simply ignores the threat to her h2-rook and grabs the White f2-bishop with her knight, 43 ... ♘e4x♗f2!.

Position after 43 ... ♘e4x♗f2!:


click for larger view

The tactical point is that the Black h2-rook is taboo on account of a <ROYAL FORK>: 44 ♔g1x♖h2?? ♘f2-g4+.

(VAR) Position after 44 ♔g1x♖h2?? ♘f2-g4+:

Nov-13-07  Riverbeast: notyetagm, are you giving us all a lesson in painfully obvious tactics?
Nov-13-07  RookFile: Bad things tend to happen to you when your opponent has a queen and rook controlling your second rank.
Nov-13-07  Riverbeast: Karpov was playing like the Karpov of old, until he got his winning position - then it seemed like his technique went out the window.

After 29...Qb8 white should have a relatively comfortable win. Maybe 30. Qf3 was stronger than 30. Qe4 (I know Karpov hates to decentralize). But this allows for Nc3, and the knight can hop to d5 or e4.

Karpov compounded this mistake with 31. Rd3, allowing the queen infiltration, and Nxa7, allowing the rook to come in...But the position is already getting problematic. If white tries 34. Rd3, black can repeat with 34...Qc2 35. Re3 Qc1.

What a disaster for Karpov to lose a position like this.

Nov-13-07  whiteshark: I like the <WAY> <notyetagm> is presenting his <COMMENTS>.

<♔A♖♙OV> should have played <38.♙f5!> ,


click for larger view

which <ATTACKS> ♘e6 as well as ♙g6... :D

Nov-13-07  MaxxLange: I think it's <ANNOYING> and <POINTLESS> and interferes with <READABILITY>.
Nov-13-07  Shams: I think <notyetagm> spends a fair amount of time around young children.
Nov-14-07  Ulhumbrus: 30 Qe4 concedes the c file to Polgar. 30 Rc1 occupies it but allows Black to take the d file by 30...Rd8. However as Polgar follows the move 30...Qc8 with the invasion 31...Qc2, this suggests that it may be easier to White to defend the d file.
Jan-20-08  mikecy: Karpov played excellent and with nice piece mobility and positional advantages as well especially after f4 move we do relaise the great game by a gm of Karpov favorite style, Karpov made the same mistake as he did in 1984 against Kasparov, playing petrof defence, estimated wrongly the defence capacity of his pieces.

Does any body remember the game of 1984 after Karpov move Rf7.
