> you might ask, "Check it down?" In a heads up game? Really? "Check it down?" ???

  The example applies more to a ring game, where you might be going after a particular fish and don't want to get involved with a better player. Still, I think it illustrates the principle of trying to keep the variance down. Also, if you're first to act on the next round, it might be worth asking, even if you don't think they'll agree.

    That's collusion and it's not cool. No top pro would ever seriously ask to 'check it down' Kelly's criterion and the sharpe ratio is not relevant for the format played in these human-AI heads up games. They play with an unlimited bankroll.

      I'm not talking about a tournament. And yes, it could indicate collusion. But most of the time, it's just a friendly low- or mid-stakes game and the players are tired of thinking. My point exactly about the unlimited bankroll. The experimenters may not have realized that an unlimited bankroll would significantly affect the strategy.
