JJ oop vs a nit in multiway pot- flops an overpair

[pofigistka]

Villain is 14/10 and has raised the limp of a 52/6 player. Should i be popping it up again here often. What should I be doing on the flop. Is he flat calling to set me up to stack off with marginal overpairs or floating me with missed overs? I generally find aa/kk simply shove here, but I presumed this was a thinking player with AA/KK thoughts appreciated..
