50-100 calldown

game is playing pretty agro like most hsnl games. i havent seen anyone limp yet so i was very confused on what type of range to put this guy on. anyways i just sat so i don't have much of an image and i haven't played w this guy before but my friend was telling me he was bad and to sit so i did.

4 or 5 handed on fulltilt effective stacks 10,000

utg (luckyULSA) limps and I raise to $400 with JJ from SB
BB folds and utg calls

flop comes T 8 8 (rainbow)
I check (thoughts?) and call $850

(2600) T 8 8 2
I check and call $2200 or something

(6950) T 8 8 2 Ace!!!
I check and call all in for 5,000ish
