Am I the worst hand reader 400 NL ?

I think this is pretty close. If this guy is really ballsy, he might be trying to push you off a king, b/c your line really screams king here, but OTOH I can't see too many opponents going for a river c/r with 8s full as the board making 2 pair on the river will lead to less river bets by Hero. Pretty much any pocket pair checks behind river, Ax, and maybe even Qx or Jx hoping to play board.
