A Fischer Botch?

My current bedtime reading is 'The Day Kasparov Quit', a New in Chess book by Dirk Jan ten Geuzendam. Nearly every interview has several points worth pursuing. Most have them have to do with chess politics, World Championship politics in particular, but there is an occasional item relevant to a famous game.

The latest passage that caught my eye was a remark by Korchnoi (p.238):

Even a splendid chess player is capable of producing negligent or botched work! Like Fischer with the analysis of this game [Fischer - Korchnoi, Stockholm Interzonal 1962] in 'My 60 Memorable Games'. He must have thought the public would be happy with anything he did.

Having no idea what Korchnoi was talking about, I turned to Chessgames.com:

Robert James Fischer vs Viktor Korchnoi, Stockholm Interzonal 1962

One kibitzer wrote, 'In his new book, Korchnoi shows how Fischer has quoted his (VK's) comments in his own (RJF's). And gives some more analysis. Better moves he suggests are: 21.Bd2 or 21.Re2; 23...g6; 35.Qf4; 36...Rb7; 37.Rc6 or 37.Bd3. And of course the crucial ...g5 on 38. and 39.' • Fischer contradicted Korchnoi's opinion on several of these moves. Did he overlook something in his own analysis?

Here's a memorable quote by Bronstein (p.237): 'Just because you didn't become World Champion everything you've ever done is put in a completely different perspective. There are many strong grandmasters, but apparently none of them can compare to these great champions.'
