BB v SB RFI - MDA exploit [Tombos21]

* all the different groups / hand classes have a different purpose vs our opponent's strategy

Exploit Adjustments - how to leverage specific hand-classes:

(1) opp dsn't 4bet enough: we get to start 3betting aggressively with linear range - all the merged value, BWs, SCs

(2) folds too much - can 3bet all the mergy trashy hands as in the pic above (A2o,..)

bonus: if you build your strat using the hand classes above, you're pretty much undetectable - bc all the hands are mixed in the overall strat anyway

this BvB equilibrium generalises to other spots really well (!):

BU facing CO open:

vs fish with: low fold, low 4bet, high call - how do we play the hand classes:
  • thick value - always 3b
  • merged value - always 3b
  • polar bluffs - fold
= go 3b or fold, completely linear

vs reg who plays 4b/fold 
= 3bet polar (hands happy to call the 4bet or fold), call merged value (merged value 3bet - the EV goes close to 0 when we get 4bet)
