Kibitzer's Corner
Jul-30-03  Ribeiro: A mistake made by Petrosian...
Jul-30-03  ughaibu: Petrosian was somewhat known for a habit of extreme blundering, the most publicised case was probably from this game: Petrosian vs Bronstein, 1956
Nov-30-03  Spitecheck: Soltis or Suetin, don't know which haven't got the book on me right now, state that Petrosian's resignation was premature as he can play .....d4 and then ...Qd5. He probably resigned out of disgust, 7...Ng6 is a blunder in the Winawer is it not?


May-03-04  ThePurplePimpernel: 'Twere definitely Soltis. Better to lose a pawn than the game!
May-03-04  TrueFiendish: 7...Ng6 certainly looks contrary to many of black's ideas in this opening. 7...Qc7.
Feb-07-05  eyalbd: In his book (in Hebrew) Liberzon mentioned 15...d4 but said that the position is lost anyway. I am sure Petrosian resigned out of disgust.

I think it's the shortest defeat of a reigning champion ever.

Aug-27-05  Titicamara: Is this his shortest ever defeat?
Aug-27-05  percyblakeney: <Titicamara> Almost: Kotov vs Petrosian, 1949
Feb-08-06  darook: Liberzon (who was a funny good spirited gentleman) said about this game (he said it in the late '80s or so) something like (not an exact quote…sorry):

"Actually, when I played the bishop to e3 I didn't intend to "win" his queen. Then I saw the position and though to myself- "this is another Petrosian 'Queen Donation' (Petrosian was an infamous 'queen blunderer') how lucky for me!". Petrosian looked very surprised after my bishop move, and for a few minutes I (Liberzon) and I think that he too - thought the queen was really lost!.

Imagine, 2 top GMs missing a 'simple' beginner's move. I don’t feel too bad about missing that move, because the World Champion missed it as well…".

Feb-22-06  Schlechter: how come you say its a queen blunder
isnt it a bishop blunder
Sep-10-06  Boot1bullet: Tigran Petrosian was my favorite chessplayer. I can't imagine he blundered this way using his favorite defense(French).
Nov-27-06  percyblakeney: <In his book (in Hebrew) Liberzon mentioned 15...d4 but said that the position is lost anyway>

It's still a very early resignation, Rybka sees white as +0.59 after 15. ... d4 and it ought to be far from over, black is after all the World Champion.

  plang: Liberzon refers to 7..Ng6 as "an unsuccessful experiment".

  GrahamClayton: Does this game still hold the record for the shortest loss by a reigning world champion?
Jan-03-10  swarmoflocusts: <percyblakeney>

Really? Fritz 11 sees that as +1.27, 19 moves deep. But Rybka is better...

  perfidious: For another method of avoiding the Poisoned Pawn (7....Nf5, popular for a time), see this crushing defeat of Iron Tigran: Stein vs Petrosian, 1961.

  whiteshark: I'd like to repeat the question:

<GrahamClayton: Does this game still hold the record for the shortest loss by a reigning world champion?>

btw, Tim Krabbe called it <the quickest regicide> in 2000.

Premium Chessgames Member
  whiteshark: Against a lesser opponent, that resignation would have been early. After <15...d4 16.cxd4>, White <'has the pawn and the compensation'>, as Roman Dzindzichashvili used to say, but Black could struggle. Suprisingly, he could even have struggled after <15...Qc6; 16.Nd4 Bxd3 17.Nxc6 Nf5 18.Qg5 Bxf1 19.Nd4 Nxd4 20.cxd4 Ba6> etc. and White still has some work to do.

Understandably, Petrosian did not fancy being subjected to that kind of work, and was probably too disgusted anyway.

~ Tim Krabbe,

Apr-12-19  Caissanist: Soltis (in <Chess to Enjoy>) states that Petrosian simply missed the 15..d4 resource, and that was why he resigned. As Soltis points out, he had drawn worse positions in the Botvinnik match the year before.
Apr-12-19  Granny O Doul: If it weren't for the fact that he resigned immediately, I'd have guessed that Black's ...Bb5 with ...d4 next was a deliberate sac to eliminate White's bishop pair and to dominate the light squares in the center.
