I only read the first few responses because it is very late... but it appears as an easy fold. Against a "terrible player" there is no reason to take a coinflip at 2:1 when there is a good chance your a behind anyways. I'd be more inclined to push with AJ here than 4's because I think a mid pair or mid-ace is fairly likely.

But is bet like someone did already say... commits him to most flops and any push from you preflop. Fold.
