[Stealthy]

I will always check here after being set up for a fresh check-raise a few times here. In this case we have to call a raise for our nut draw so prefer to check behind and see what develops almost every time. The only time I will fire here is if I have a good enough read to say that he would play a flop that way but could lay his hand down on the turn for one more bet. These players are rare.

Your fold equity is almost non-existent and a check is correct. You may have to still call a river bet UI though as his check could mean that he was making a play with no hand on the flop and ace high could well be good.
