I had a 3k session of non zoom today, and I played profitable from every position, but the blinds absolutely smashed me. I have started taking poker a lot more seriously the last two weeks or so, and before this my longest session was maybe 400 hands, so putting in 3k in a single day was a lot for me. Anyways, I've been keeping track of how i'm playing using poker tracker, and from every single position I played profitably, but the blinds smashed my win rate to the point where I'm down 3BI. My red line is almost linear downwards, while my blue line is positive. I noticed what would happen is I would play in big hands, win a fair amount, then lose almost 25BB by just getting slowly blinded out as the hands went on. . I'm thinking I'm not stealing enough from the SB, and overfolding to BTN/SB steals,which may be my issues. I'm just curious though, is it common to get slammed by the blinds this much? Or am I just making too little from other positions to be profitable? Any help is appreciated, because I think this is a huge leak in my game.
