In some simuls, GMs give each player two "passes." Kasparov ought to have done that for this simul because it wasn't like there was 30 to 50 players that would allow for a decent amount of thinking time. I also think $3,000 per player was too steep and would have passed on the chance to play him at that cost (at least in a simul - if it was a G/120 I would have scraped together the money somehow lol.)
But the OP's coverage of the simul is awesome. Best thread I've seen.
I could tell nerves played a part. But nice shot
