4bet bluffs SB vs BB

[BorisTheSpider]

I'm working on some new ranges, and I wanted to get some opinions on what kind of hands to 4bet bluff with when opening the SB and getting 3bet by the BB.

I am assuming a 2.5bb open, 8bb 3bet and 16bb 4bet, meaning if the BB flats a 4bet and we see a flop, we have 84bb behind with a 32bb flop pot for an SPR of 2.6:1

In this scenario, would you rather have stuff like SCs that can sometimes flop a strong enough draw to continue aggression, or some junky suited KXs QXs type hands that can make a reasonable top pair on the flop?

I'm 4b Ax hands (A6o, A5s etc) and assuming villain will not flat a 4b until proven otherwise.

Once I know villain is the type to just rampant flat all 4b, I'll probably start 4b a more merged range with stuff like AJ/KQ etc.

I'd open 3x from the SB. I'd also be 4betting more than 2x OOP.

Yah I'm probably going 3bb, assume they will go 9bb and I'll make it like 19bb

3bb/9bb/22bb is my standard in this spot. I find villains won't fold at 25nl and lower if I 4bet smaller.

I think you need to think about some BvB pre-flop stats for villain before you can start this exercise. FWIW, I've got BBvsSB on my HUD pop-up and find it incredibly useful. Some villains go spacker BvB, which might not be immediately obvious. Likewise, I have all the resteal stats on my HUD, as some other villains also go crazy btn vs co for instance - they may have a 3bet of 6% say, but then you realise that they only ever 3bet btn vs co an absurd amount and 2% in other seats.

Blockers are where it's at it here. I haz some default ranges in this spot vs regs where I 4-bet a good bit but not enough so that they can ship stuff like 66 on me etc. I think this is good at 100 as people love to 5 bet light, at 25NL though you probably want to be 4 betting wider than that as light 5 betting is pretty rare (I think) and so your 4-bet bluffing frequencies should be higher. You also want a tighter 4-bet call range than I want. You can pick and chose a range that = X amount of bluff combos, base X on how many value combos you have Increase or decrease X based on how often you want to be bluffing vs a default unknown reg at your stakes.
