3betting all 55+ and K9s-K6s BvB feel like this strat with these ranges will be pretty influenced by which preflop (rake structure?) ranges are used?

Great theory vid!

6:35 it seems like our front door flush draws prefer the smaller size and the bdfd and no fd combos like to jam. To me it seems it should be opposite since we push more eq with the front door draw. We especially benefit from fold eq with the lower flush draws where we can fold out over cards.

11:50 shows if we chk then ip bets a lot of tx. Is this to barrel off as a bluff?

Thanks!

Enjoyed the video! Lots of people making big mistakes in 4bet pots so definitely somewhere we can find some exploits. I have been looking at ranges for BB flatting SB's 4bet, and they differ a little in how often BB flats AKs and KK vs the 4bet. The ones I have seen range from ~50% flatting for both hands to 100% flatting for both hands. What made you go for 100% flatting in your ranges?

In single raised pots and 3bet pots, most people recommend using just one bet size on flop with your betting range. Do you think that in 4bet pots it's reasonable to have 2 bet sizes on the flop, given that they are somewhat simpler scenarios due to the shallow stack depth? I'm thinking that in the specific scenario of wanting to have a small bet size and a shove it could be useful and manageable to have 2 bet sizes. Are there any other scenarios where you would think having 2 might be worthwhile?
