Hey,
In both scenarios iss
MP loose fish
CO regular players . His overall iso raise vs. one limper is 30%.
Hero 3bets as BTN 12%.
Hero 3bets as SB 10%. We play oop so I think that 3b range should be narrower.

My questions::
1. What do you think about my ranges. I personally do not have any calling range. Is it wrong?
2. When I play IP I 3b 3X. When I play OOP I 3b 4x. What do you think about my size of bets?
3.What do you think about opponent's 4bet sizes? Is it correct? Do you use similar 4b sizing or only shove? WHY?

Please forget that it is NL25. I'm interested in theory.
BTW: What do you think about villain's Iso range? Is it wide? narrow? What is yours?

Thank you so much!
