Final Pot: $52


After he called the flop raise and led into me again, I didn't think I had enough FE to make shoving turn +EV. However, I did think that with only 20 behind and a $52 dollar pot, the rest was going in on the river, so I just called turn. After missing the river, I assume the fold is obv.
