would you call this ?

Folding was correct with the jacks. He's either got jacks beat with a bigger overpair, he hit a set or a possible straight. Chances he's bluffing with a pretty likely call are just too slim. You did the right thing folding.
Only possible hands I can see you beat here are 77-TT, and I don't believe in them.

Also, the tens were a gross overbet. Pot was only $4, right? Then why bet $6 when you actually want a call? Also, your hand's pretty much a lock, so you won't mind the other guys improving. Bet a bit less than the pot, about $3 should do it, imho. Turn's better for bigger bets here.
