Tell me how did I play this hand? I am not sure about the sizing of my 4bet. Pokersnowie recommends
something like 3x but I use 2.5x oop as the microstake coach said. What's your opinion?

On the flop I really didn't have any idea what to do. Very small spr, possibility to hit A or K. I went all
in and wished opp to fold his, hmm, 4bet calling range, maybe 88-JJ, AK, AQ,
