Everyone wants to see more hands.

Raise on flop to get rid of stragglers, such as better flush draws. Now what? I mean, how much? Villain has less than the pot behind on the turn.

Pre-flop: (9 players) Hero is CO with 9 Q T Q
2 folds, MP1 raises to $1, MP2 folds, MP3 calls, Hero calls, Button folds, SB calls, BB calls.

Flop: 4 J Q ($5, 5 players)
SB checks, BB checks, MP1 checks, MP3 bets $4.75, Hero raises to $15, 3 folds, MP3 calls.

Turn: T ($35, 2 players)
MP3 checks, Hero ???

If we bet and he raises we are calling anyway.

Instead I may check and hope he bets his lower flush or lower set on river.

If i bet , i bet 18$ to make sure he can't fold on river if he flat calls turn.
