I'd likely check and fold. He could fold A8 to a flop bet, but most likely he's got at least pair and has you drawing to two outs. He may check behind A8 too, fearing a check-raise from hero. Then if a brick falls you can bet the turn hoping villain folds A8 (there are many cards that kill your hand on the river). You could bet/fold the flop, but this flop is too menacing I think to even bother putting in a small bet.
