Seems like a good spot to call flop and turn and raise the river. You maximize value against bluffs and with his stack size he can't 3-bet the river if he's ahead.

This might actually be the best line against an opponnent with a full stack, at least if you think he's sane enough, that you can raise/fold the river.

Being really worried about being behind, when he raises the flop is weak/tight thinking. Sure it's possible, but in reality not that likely (meaning it's a lot more likely you're still ahead). There's a lot of weaker jacks, pocketpairs, acehigh hands and pure bluffs, and people often wait for the turn with trips.
