One decision, out of position on the turn. The pre-flop raiser checked the flop back — and that single passive action hands you a betting range you did not have a moment earlier.

Hand history
Pre-flop
Flop
Turn
You called UTG’s open in the big blind and checked the 9♥ 8♥ 4♦ flop. UTG checked behind. The turn is the 5♠: it gives you a set of fives — and it is also the card that completes 7-6 for a straight. The pot is still 5.5bb, you have 37.5bb behind, and you are first to act.
