jfyi the flush completes otr.
he can have a really depolarized 3bet range and have like j7, k8 in his range as well as 910/jj for slowplays, or 108ss, 98ss, j9ss, j10ss etc.
with a 5% 3b I'd expect him to have a polarised range...
I also don't see why he wouldnt go for 3 streets with his value hands when the board just gets wetter. He might even go for the c/r ott with nutted hands.
I know the flush completes otr, but he can't have 8xss as the

is out, but I expect him to db jxss when he picks up more equity.
