BB is 29/9 over 70 & BTN is 19/17 over 1.9K

The best read I had on the BB is that I'd seen him call an overbet/shove with QQ a few orbits ago. BTN seems pretty decent, but likes to 4bet light so I'm thinking he's got AJ+, broadways and JJ+ (is that too wide). HM poppup indicates a 16.4 4bet range (not really sure what that means)

I'm mostly concerned about bet sizing.
