If he called the turn, I was shoving the river. Position, deep stacks, and judiciously employed small bets are a lethal combination. It’s exceedingly difficult for him to show up with enough big hands to prevent me from exploiting him with river shoves.

If both players employ game theoretically optimal strategy, the advantage will obviously go to the player in position. His EV in the game will be a function of the pot size and the number of betting rounds, meaning that it behooves him to structure the betting so that there is roughly a pot-sized bet remaining on the river. He can then maximize his edge by making better decisions than his opponent about when he wants that last bet to go into the pot.

The player out of position is fighting an uphill battle. To balance his range, he needs to slowplay big hands quite frequently, make some heroic call downs, and float the flop out of position with the intention of check-raising the turn on a bluff. Most players can’t do any of those things, let alone all three.

  1. This is a tantalizing post with some really interesting ideas that need more meat. Can you say more? In my experience, trying to blow someone off an Ax hand is just too disruptive to my bankroll. Many players are just too stubborn and will chk-call all three streets. I finally learned that my best counter-strategy is to simply bet the hell out of my hand when I can beat Ax. Turning 2nd pair into a bluff in the hopes of blowing someone off Ax? I dunno, I need to hear more.
