I check because he wiill never call with lots of holdings that we are comfortably beating.

I'd also like to know what draws exactly everyone if referring to. Think about this: don't just consider that because we see two clubs and three broadway cards that this means we can't give a free card. If he's called pre-flop with clubs, then they must be connecting (because Ac has flopped). If they are connecting broadway clubs, we are toast anyway. He's not folding and we are a dog. It is not impossible that he has called with clubs that do not also offer him a straight draw but that would be very bad play with stacks this shallow against an UTG raiser.

How about straight draws? Well, again, he's not folding and he is often ahead.

I really don't see any benefit to betting this flop. What exactly are we protecting our hand from? He will not call with a worse hand.

If we check the flop, he might bet with a worse hand or make one stab at it with a better hand that we can overtake. If he has two pair, for example, I doubt he will bet twice at this board.

I think we're pretty much obliged to call off all our chips here, this shallow, but to bet all of our chips into a better hand which probably feels too vulnerable to get it all in itself, seems a little rash.
