I'm playing around with various reasonable 3betting ranges SB vs. CO and I just can't even get you 40% on this flop versus any 3betting style with your exact holding of KQcc. I've tried Axs heavy 3bet range, suited connector heavy range, pocket pair heavy range, value heavy linear range, all of them just wreck this flop.
As played flop call is easy for this sizing as we need to defend ~63% of our 3bet flatting range to this cbet sizing across our whole strategy. On this dynamic board we should call cbet with much more than MDF (~80%+) as we hit it harder in general (or at least as hard) and we can flat call less cbets than the MDF on more static boards.
If we flat something like JJ, TT, 99, 88, 77, 66, AQs, AJs, ATs, KQs, KJs, AQo, AJo, KQo, QTs, QJs, JTs, T9s, 98s then our exact hand is actually one of the worst in our range on this board but still a call because we pretty much continue everything except AQhh AQdd KQo, 66, AQo. Continuing with 80%, sounds about right to me...
Rangewise you're actually almost definitely ahead on this flop. With KQcc behind but still fine as played.
On this turn I could be wrong but I don't think we need to call again when we have so many sets, two pair, combo draws, straights and QQ/JJ in our range. Again I could be wrong here.
This all changes if you have nitty flat vs sb 3bet range of course.
