140bb's effective stacks to start hand: 

I open to 3x UTG and BTN 3b's to $6....I call. On the flop villain bets 1/2 pot and I decided to call. On the turn villain bets a tiny bit more than 1/2 pot and my instinct is to actually call turn and call river. What would you guys do OTT? 

I have been at the table for about 25 hands and have not seen villain get out of line or play many hands....have not seen him reach showdown.
