BTN open facing 3bet // blinds facing BTN open

optimal strat for opening 35% btn facing a 3bet:

4-bet {QQ+,AK} =34 combos for value
4-bet {ATo,A9s-A7s} =24 combos as a bluff
Flat {JJ-88,AQ-AJ,ATs,KQ-KJ,KTs,QJ,QTs,JTs} =120 combos

optimal strat for a villain facing my open:

- defend about 17% of the time (more when flatting)
- value 62 combos AQ+,TT+ (we 3bet/ 5bet these)
- flat 70 combos 

- bluff 100 combos (see Equilab stored range)

it's mostly button openraising that forces the blinds to defend very aggressively, and that we can play much tighter against raises from earlier positions

vs 2x btn open blinds have to defend 43% combined


vs 3x open its 33% combined (~17% each blind, BB should defend more)


^^ this is true when we defend by 3-betting. if we defend by flatting, we have to use 1.5 call multiplier, because we let btn see flop and realize some equity.
