Flopped Boat...To Slowplay Or Not?

No reads on villian. I've been playing tight aggressive I assume.
Do you raise or just call here?
My thinking, the smallish bet on the flop leading into me looks like a feeler bet with a smaller pair. If I'm right I'm almost a lock to win. I doubt I'll get too much more if I start firing away. Any thoughts?

Hero…

considering that our opponent if hes at all tight is likely drawing dead, a call wouldnt be bad but a raise is pretty standard here. A lot of donks bet A high here and what not and may even take A high all the way if there donky enough.

This is a *must raise* to me.

Slowplaying will make you win small or lose big. If villain doesn't have a hand worth calling a flop raise then he's not putting any more money in the pot unless he turns/rivers you.

Raise definitely, you want the pot size to explode so the donkey feels inclined to get his stack in with 33. If you call and an A-T comes your action is killed.

Reasons to slowplay are to let villain catchup, in this case there's nothing that deceptive about our hand and a good chance we're caught up to. Bet.
