Playing in position against a three-better is a lesson in playing to your advantages. As the defending player, you will not have the equity advantage or the nuts advantage. What you will have is the positional advantage. This incentivizes you to play even more passively than you usually would as the defending player facing aggression, forcing your opponent to make tradeoffs and reveal information by acting first on future streets while you bluff, pot control, and squeeze extra value from marginal hands. Deeper stack depths magnify your positional advantage, as do more dynamic boards, so you’ll need to assess these factors to determine the incentives of your specific hand in any given situation.
