If you must bet the flop, bet bigger.

It wasn't too quick, your opponent was on a draw or had a very weak hand.

hero checks the turn.

hero then raises the turn bet and watches as the opponent folds.

"should I of just checked the turn and push river?"

your play is fine, tho I usually check the flop unless I really just want to take down the pot. Let the aggressor give your money and then give the aggressor a really, really tough river decision where could have pot odds to call with tptk
