My results so far:

Doesnt look good but im not a losing player. My nonsd is -10bb/100 if i could fix that and lose only half of it i would have nice winrate. I dont ask you for the answers, i ask for tips where to start to find spots/situations that cause me so much losing.

here are graphs by positions.

SB+BB:

UTG+MP:

CO+BTN:

By looking at these graphs i can say that blinds are my biggest leaks or maybe im not winning big enough from other positions to cover losses from blind?

Could you recommend me some books/coursers or RIO series about defending vs cbets OOP at nl25/50? I have these GTO charts to defend vs sizing + PFR so preflop its not a big deal to me.
