100nl: JJ on a good board

[Nikachu]

Villan was running around 25/22 is over a small sample size of 50 hands. I probably looked like a 29/25 to him. This particular player had 3 bet me Preflop quite a few times but I've only seen him show down solid hands. In my view hes a solid player.

Two questions...
1) What do I do if he shoves?
2) If he just calls and the turn is safe... should I just shove?
