I like to call preflop. A raise is not to bad though.

I play it the same... If he does this too often I start calling though. If he had the straight, wouldn't he be better off betting less? He's either vbetting too big, bluffing, or bluffing and vbetting this big. Try to find out which one. If he's a regular I might look him up after a couple of these bets to find out.
