Hey, I've been lurking here for a while- this is my 1st post. Villan in this hand just sat down.

I'm in the CO w/99

Preflop
UTG raises, MP folds, I 3-bet, Button folds, SB caps, BB folds, UTG calls, I call. (13 sb)

Flop- Ad, 7h, 5s
SB checks, UTG bets, I call, SB folds. (15 sb)

Turn- 8d
UTG bets, I call. (8 bb)

River- Ah
UTG bets, I fold.

I gave myself about 3 outs on the flop and picked up my gutshot on the turn. I think I had odds to call these bets, but felt like a huge fish calling down. Does anyone else play it like this?
