Playing vs unknowns in 3bet pots
With a big sample on your opponent you can easily take the exploitative action vs them. If they 3bet really wide you can defend a wider range, if they 3bet hardly ever then only continue with a tight range or to setmine if the odds
Postflop it is also straightforward. If they always cbet the flop and rarely cbet turn then just float them in position. If they tend to barrel a lot then slowplay your strong hands vs them and call down light more/turn marginal hands into bluff raises on the flop. Easy peasy.
But what do you do against a totally unknown player? What is your DEFAULT strategy? Please answer these questions (assume standard bet sizing etc):
1) If you raise from the BTN and an unknown resteals, what range are you defending and how (call or 4bet?)
2) Let's say you raise 99 from BTN, unknown resteals from BB, you call. Flop comes J72 and he cbets a standard amount. Do you fold, call or raise? if you call and he cbets turn on a brick, do you call again? if you bluff raise and he calls, do you shut down completely?
3) Also BTN vs BB, but this time you have KQ and flop comes Q72. He cbets you call. Turn is a 3 he cbets again you call (ever fold here?). River comes a 2 and he shoves, do you call? If not, do you call with AQ?
At the moment i only defend a very narrow range vs unknowns until i figure out their style. I will even fold 99 and KQ (even AQ) pre in the instances above due to not knowing what to do on most flops. Could someone please elaborate on their default strategy vs unknowns and explain how they'd handle the instances above?
