[4_2_it]

Pre-flop -- Don't min-raise. Make it 3or 4xbb plus 1 bb per limper so $4-5 should be your play.
Flop - Pot-sized bet is what you want to do here, especially since it is multi-way. You just gave every draw in the world correct odds to call.
Turn - Bet more (see above)
River - You missed your chance at redemption. All-in.

As soon as you flopped top set your plan should have been "How do I get all the money in the middle". Underbetting because you have a monster and are afraid everyone will fold only makes it correct for draws to call you down, hit and suck you dry. Don't play your monsters any differently than AK or TPGK.
