Hero...

Equal definitely threebets light and I'm certain BB is calling with any two to a fourbet. I was really unsure of an amount in this spot, because I didn't want to offer Equal attractive pot odds given that he probably knew the BB was going to juice the pot and we were semi deep. Thus, I shoved, but it felt pretty donkish reraising 65 with 700 even though I knew the BB was going to call. Suggestions for amounts? Can I entice AK/QQ to shove if I fourbet to 300 or so?
