Can someone elaborate why we want to use smaller bets here? I get we have a similar number of nuts, but we have all of the overpairs. My initial instinct wasn't to go small here. With some review, I can see using a small sizing and doing this with our range, because things like JJ capitalize on dead money, and can get some thin value.

with very narrow ranges, why is it a thing to bet range here rather than going bigger and having some check backs?
