Scenario: we are in the CO and position named (UTG, LJ, HJ) RFI 2.5x preflop. We are in the CO with Q9s
- CO vs UTG + 2 = -0.11 EV
- CO vs LJ = -0.06 EV
- CO vs HJ = -0.02 EV

Above you can see some different scenarios I have checked out in PokerSnowie in relation to what EV looks like if we 3-bet. In these situations, all the 3 bets are -EV. What I have in mind is that even if some plays are -EV against a random player, it can be + EV if we play against a fish. My question is therefore the following: How much minus EV can a typical 3 bet hand be for it not to be profitable against a fish. How bad the fish is and how well we play after the flop is a factor, so i know that this is a difficult question.
