How about his 1964 San Francisco simul? A simul he scored 4.5 out of 9, all against unknown unranked players.There are also quite a few simuls during his 1964 simul tour that didn't go so well.
Here's one of Fischers simul losses, hardly an impressive game.
Raul72, this isn't a matter of opinion, if you think Fischer won every simul game he played, just check or get any major database, most of which contains Fischers simul games.
Tricklev, I dont believe it. What are your sources. I know he played a ten game clock simul at Davis college against masters and experts and went 10-0. One of these games (#50) he included in my 60 memorable games.I cant believe he went down the road a piece and went 4 1/2 out of 9 in Frisco. The S King you refer to is Stan King, vice president of the USCF. I dont believe it! You probably mis-read it. Bobby could be playing the top GMs of Russia and he is not going to go 4 1/2 out of nine in a clock simul. That aint happening (without an explanation). Maybe he just had a car accident going to Frisco and half his brain was hanging out. Maybe someone slipped him a mickey and he played in his sleep. I dont believe it.
