For example, it recommends a half-pot turn bet if the middle player to act in a three way pot after three checks on the flop.
The following shows a player who has checked in this situation with 64o, but it would be profitable in the long term if this player had bet 60. It assumes the first player had nothing from the turn check, and the hope is that the last player to act also has nothing judging from his check on the flop.
However in this example, the cutoff made a very small bet and took the pot, probably knowing the other two players had not hit the board.
