This flop is K high and with our linear SB 3betting range I think we can cbet quite aggressively. Maybe using a smaller sizing than standard (go down to half pot or slightly under) and cbet linear.


Cbet V: AA (3)TT-QQ (9), 89s (3), 99 (3), 88 (3), AK (9), QK (9), KJ (9), K9s (3), K8s (3) = 54
A2dd-A7dd (6), 45dd-67dd (3), TJdd-QJdd, QTdd (3), 46dd, 57dd (2) = 15

Cbet Bluff: AdQx (4), AdJx (4), AdTx (4), TJs (3), QJs (3), 8Ts (3), 67s (3), 56s (3), 75s (3) = 30
Semi bluff?: A9s (3), A8s (3), Q8s (3), Q9s (3) = 12
AQ: 12 (blocks KQ and AdQx) = 12

Tot 123 combos cbet or 50% on this flop.

C/C: AdAx (3) AdKx (3), QdKx (3), KxJd (3), KK (3), AQdd, AJdd, ATdd (3), TdTx, JdJx, QdQx (9), 9Ts (3), 9Js (3) = 33


To this flop raise, we have to defend 50% of our range. And since our range is so strong in this situation, we could be 3betting our hole range here, but I think some hands just hate to get it in, like AA and AK no diamonds. We will still 3bet aggressively though. I look at the range something like this:

3bet flop with (assuming 100bb stacks now):
 45dd-67dd (3), TJdd-QJdd, QTdd (3), 46dd, 57dd (2) = 11
89s (3), 99 (3), 88 (3), K9s (3), K8s (3) = 15
AdQx (4), AdJx (4), AdTx (4) = 12

Tot 39 combos

Calls:
A2dd-A7dd (6), AA (3), AK (9), QK (9),  = 27
TJs (3) = 3

Tot 30 combos

Tot 69 combos defended or 56% of range

Summary: I think 3betting the flop agressively with a lot of hands make sense here, but keeping a calling range protected with all nut flush combos.
