In Position (IP) (IP)

Also known as: In Position, IP

Acting last postflop. You see opponents' decisions before yours, realize more equity, and can check back to control the pot.

Being in position (IP) means you act last on the postflop streets — after every opponent has checked, bet, or raised. It is the single most valuable structural edge in a hand.

Why IP wins:

Information: you decide with full knowledge of what everyone else did this street.
Equity realization: the same hand realizes more of its raw equity in position, because you rarely get blown off it and can take free cards.
Pot control: you can check back marginal hands to see a cheap next card instead of being raised off them.
Cheaper bluffs and thin value: closing the action means your bluffs face no check-raise on that street, and you can value bet thinly because a check behind is always available as the safe option.

This is why you open wider on the button and cutoff: you expect to play the hand IP. The mirror image is playing out of position, where you act first and surrender all of these advantages. A float — calling a flop bet in position to take the pot away later — exists precisely because position makes it cheap to apply pressure on later streets.

Example

You call a button open with A♠Q♠ in the cutoff... actually you raise the button. Flop comes K♠8♦3♥, BB checks, you check back to control the pot with an overcard hand. Turn Q♣ gives you top pair — now you bet for thin value, with a free river check always behind you. That option only exists because you are IP.
