50NL - tough spot with JJ in a blind battle

[NNH]

50NL 6max
No real reads on villain, only that he bought in short and has worked his stack up. He probably views me as tight so far.
Effective stacks are $50.

All fold to Villain who min raises to $1. I make it $4 with black JJ. He calls.

Villain checks, I bet $6, he calls.

Villain checks, I bet $10, Villain pushes

Comments on all streets appreciated, especially turn and my weak line.
