Fischer constantly accused Kasparov and Karpov of prearranging matches(and other Soviet players, but Karpov and Kasparov were the two primary targets.) Fischer has said many maniacal things.
"I studied that first Karpov-Kasparov match for a year and a half before I cracked it, what they were doing, and discovered that it was all prearranged move-by-move. There's no doubt of it in my mind."
-Bobby Fischer, 1999
"I was going to do a book about the first prearranged Karpov-Kasparov match, '84-'85. But the God-damn Jews have stolen my entire file on that."
-Bobby Fischer, 2002
And those two statements are not that unreasonable. Fischer was continually saying that these moves were not being played "over the board", they were arranged beforehand in opening theory. That was the point. If you listen to the full radio interview that he said that second one in, he studied the game for a year and a half before he realized that they were not coming up with these moves over the board at all but on paper in theory beforehand, and that sometimes the entire game was played this way. It's not unusual for a very strong player to study single games or even single positions for a very long time, trying to understand logically the exact purposes of every move as much as possible, and Fischer used to do that when he was world champion also. It is hugely different if they were able to come up with the moves over the board with a couple of minutes for each move. To you and I it might seem pretty much the same because we're clueless, however to one of the greatest players ever it was an extraordinary difference and highly unethical to claim they were coming up with such moves over the board.
A lot of his belongings were taken from a storage unit when he failed to keep up payments on it, so that's how he lost his notes and many of his books. It seems harsh he lost so much stuff over failure to keep up payments on time.
I know what his point was, and yes I've listened to the whole interview. That doesn't make his claims any less absurd.
it's ok, no need to be embarrassed, he was good, trolled the heck out of America and the ruskies.
