if hes super fish or reg who dont fold ever to 3bets then i dont even bet
its 2 bets lleft to get the $ in and we can check and bet turn n river in case where the board is uber dry & no cards hurt us... now what this does is get him to potentially bet bluffs or think his overpairs is good... even though he dont fold qq+ here ever he could get it in with 99 or get more $ in the pot with hands like that if we do this n hes fishy
so i half pot flop to shove turn or c/call otf n let him bluff if we think his range is very wide pre..... also over bet shoving flops are fine but on a more wet board when he has more of a calling range and when we dont want to losee value vs his draws by going multiple streets with only 1.5x pot left
OP, there's no need to bet anything more than 1/2 pot on that flop. Given stack sizes the money is going in on the turn anyway and the board is dry so there aren't really any bad turn cards for us (apart from the very small chance that he makes a set but we can ignore that).
