Hero is unsure how to proceed....


UTG seems like a mediocre TAG, stats are 26/19/3 over 100 hands. I only had 20 hands on button at the time, and he was like 20/0/1. Also, his stack size seems to indicate he's a fish.

Obv was hoping to get raised on the flop, didn't happen. Should I have just led out bigger?
