"In the end, rs03rs03 averages 120 tables at once when at full speed, playing about 100,000 hands over the course of about 55,800 seconds. That's about 1.8 hands per second (slightly more actions, though, since some hands are multi-decision)."
Can anyone speculate what strategy might allow him to play 1.8 hands per second on average?
First of all, he was playing tournaments with a buyin of $1 maximum- likely less. So he can get away with playing a very simple strategy.
He was certainly not making standard raises, I imagine he was playing a "push-fold" strategy from the start, meaning he either went all-in or folded on his initial turn to act. His range for this strategy probably included TT, JJ, QQ, KK, AA, AK, AQ and maybe a few more hands later on in the tournaments.
Cascaded tables... A table with a pending action pops to the front, and others go immediately behind it. Various helper programs put the mouse in the right place, set the appropriate bet size, register for new tournaments, etc. Basically all he has to do is click Check, Bet/Raise, or Fold (using the keyboard or a controller), and everything else is taken care of.
This is tangential to your question, but proper strategy in Double or Nothing tournaments is to play extremely tight. The top 5/10 players get just under double their buy-in back. Winning one hand can sometimes be enough to win the entire tournament, and I've even won one without playing a single hand. The point is that he's folding probably 90% of hands preflop.
