Thanks for the suggestions. I revised BB cc range to the following:
10% AA, KQs
25% 88, AKo
50% AQo
75% 99, JJ, AQs
And I input a fairly std SBvBTN 3bet range of 13.5%.
I put 40% and 80% sizes for SB figuring it might be reasonable for SB to use a big flop size to set up a turn shove vs. the capped BB range. Result is a relatively high check freq
and the 40% is the higher freq of the cbet sizes, though both are used.
Facing SB check, BB has a high freq bet, which would be expected.
SB leads range on Tx turn, preferring 40% size over 30%.
...and checks range on river. After checking, AKo is 100% xf, and as far as bluffcatchers we xc all of our AA, most of our KJs, and some of our QJs, QQ, AJo.
So my turn decision seems pretty good and riv is std. The int spot is flop where it looks like we can go either way theoretically, although the sim obv. didn't include BTN's range in the overall picture. Cbet may well be better though, esp. if BB doesn't flat that much AQ pre (he would bluff it prob at least two streets a good amt when checked to here).
Kinda strange finding that the hand that most prefers the big flop cbet size is KTs, this makes no sense to me for blocker reasons. A6s also loves the big size. Also Idk why AA, KK, are similar freq with 80%.
