CO is 26/21/8 (325), Ft3b is 47 (15))
BU is 21/15/8 (73)

Preflop: Although the lower sample to COs folding, he opens pretty wide from CO and seems to have somewhat the tendency to fold, so I think a squeeze here is pretty good.

Im having trouble to figure out BUs exact range - its stuff that they dont want to 3b themselves, but figure is still good to call after a squeeze (I figure mainly PPs and some suited BW hands). So like 44-88, 76s-QJs, KJs, ATs.. wheel suited Ax maybe?

Flop: Could go a bit lower with sizing, will also avoid weird SPRs to barrel. I didnt feel too good about my hand after his raise and thought were dominated mostly by better FDs or are up against a set, dont see him doing this with toppair too much.

We would still have 40% though. You think these assumptions are somewhat correct?
