focus area: BB defence (passive bias)

 hit that 3bet button more often - can likely get away w wider range than what solver suggests:

- all hands that are mixing 3bets in GTO-land - one can argue that they'll be even higher EV as a pure 3bet

blinds facing open from any position

vs UTG we can use same as vs MP

Minimum ~4% blind defense strategy heads-up against an MP (20%) open-raise
The minimum 4% defense is covered by:

• 3-bet {KK+} for value together with 20% of "OOP 3-bet air list"
• Flat {QQ,AK}
• This gives ~4% total defense

Alternatively

• 3-bet {QQ+,AK} for value together with 50% of "OOP 3-bet air list"
• This gives 6% total defense

Minimum ~7% blind defense strategy heads-up against a CO (25%) open-raise
The minimum 7% blind defense is covered by:

• 3-bet {QQ+,AK} for value together with 50% of "OOP 3-bet air list"
• Flat {JJ-TT,AQ}
• This gives ~8% total defense

Minimum ~16% blind defense strategy heads-up against a button (35%) open-raise
The minimum 16% blind defense is covered by:

• 3-bet {TT+,AQ} for value together with 100% of "OOP 3-bet air list"
• Flat the whole "OOP flat list": {99-77,AJs-ATs,AJo,KTs+,KQo,QJs,JTs} =70 combos
• This gives ~17% total defense

Cliffs: its very hard to exploit blinds from EP, so you shouldnt worry too much about defense.

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.

fact - blinds defense

How often do the blinds need to defend combined to prevent the btn to open profitably ATC ?
(if they only defend by 3betting - if u defend by flatting u need to defend even more obv cos hes got to see 3cards and will realize some of his equity)

-> 37.5 % (2.5bb btn open)
