Final Pot: $30.50

no reads on opponent. In hindsight, i should have probably bet the turn and put my opponent on a streight draw, but at the same time I felt like that board hit a lot of hands and that I should keep the pot small and call a reasonable bet on the river.

You need to bet the turn, for value and protection. You'll get calls from T,6's all day long, probably even some 9's

B/F turn..Re-eval river based on card and action...

bet 13 on turn, muck to raise. If he calls and leads on river fold, or check behind when the J hits.
