3 players calls, I have ATs on the SB, I isolate to 7bb (maybe little bit bigger will be better because of bad position). Button calls.
Only 12 hands from BTN: VPIP: 75, PFR: 8, AF: 6

Safe flop, I have a top pair with ok kicker, I make a little bit smaller than half pot bet to keep opponent in hand and get more value. He calls.
Another Jack on the Turn. What now? I don't want to show weakness, so I make a smallish bet. Opponent calls.
River is tough. I make a very small bet, and opp shoves, I have to fold.

I think I made a mistake by betting on the Turn. What do you think?
