Isn't this the Ed Miller hand?

I probably would have raised preflop. The second best option is to fold because A2s isn't a great hand to play against a slightly loose (30 VPIP) player. The worst option is to call, unless you completely rock this game postflop.

Since you limped, the only reason to fold is if you are very sure (say 75%) that he would only bet an ace here. Otherwise, you have to play it like you have the best hand and you need to extract as much money as possible (otherwise you shouldn't be limping in the first place).

The pot is small, and part of me wants to just call to help inflate the pot by getting overcallers, but that's a dangerous play and probably doesn't work often enough to be correct. So you've just got to value raise and extract from UTG.

This also means you bet the turn and river, and hope to see him turn over KJ/QJ/JT so that you win.
