This one has been nagging at me for a while now. It's from Prima $50 NL, several nights ago. All of the tables were playing very passive, very weak. Lots of weak preflop raises from big pairs.

I am in LMP and limp with [Td] after 1 limper. Folds to BB who minimum raises, limper folds , and I call. BB has $18 or so.

Flop (Pot $2.50): [6d][3d]. Super nice flop for me of course.

BB bets $3 into the $2.50 pot. With the action so far, I put him firmly on an overpair. I'm pretty sure I have zero folding equity. But I push anyway.

I know my equity in the pot is about 50%. So with the money in the pot my push is +EV. But is there a better way to play this? Hell, are there any other options at all? I feel like pushing takes away my positional advantage and my advantage due to the fact that the guy is a donk.

Ideas?

If they're passive I think you can raise it to 9, and then expect him to check the turn, at which point you can see the river for free if you don't improve.
