small bet here. But enough I think to be a weak cbet. I want at least one caller.

Turn: ($8) 2 (2 players)
Hero bets $1.5, UTG+1 raises to $4, Hero calls $2.50.

Based on how weak I look with my bet and this player I am sure this is a bluff. If I raise he folds, so I just call.

River: ($16) 2 (2 players)
Hero bets $8, UTG+1 folds.

This is where, given my line, I maybe could of made some more with a smaller bet. What do you think?
Final Pot: $16
