Final Pot: $4.40

not sure if i played this well considering i got re-raised on flop. I don't think my hand was good enough to get too crazy with but by checking the turn i let him make this ridiculous river bet which confused me. From experience this type of bet usually equals a monster but could also be some kind of donk semi-bluff.

Things i might do different...
-raise pf from btn.
-make a half pot turn bet and fold to rr.

thoughts?
