I don't think you're a losing player. You might as well be a winner in these games. It doesn't take an advanced theoretical player to beat 25nl.
There might be a difference in how we define fundamentals though. When wacker1913 talks about fundamentals he is referring to:
- Pre-flop theory (optimal sizings, why 89s generally performs worse than 65s as a flat vs 3b, rake considerations, etc)
- Ranges (nut advantage, equity advantage, cappedness, linear & polar, etc)
- Sizings (different textures, heavily dependent on range theory, etc)
- Bluffing/defence (MDF, blockers, etc)
- Frequencies (heavily dependent on all of this stuff)
- etc...
You don't have to master all these to beat 25nl, but as you go higher up you should know quite a bit of these things, atleast how they affect the game and your EV.
Correct me if I'm wrong, and I'm not trying to be offensive by any means, but I think you might lack understanding about a lot of these things (which I'm not a master of either) and how to apply them in your game.
There are a lot of resources though and we talk about theory a lot here on uNL but also in the Poker Theory section.
Shameless self-promotion: I've written quite a few theory posts in my PG&C. I have them all listed in one of the last ~8 pages of my thread.
But that's all the free stuff on here. Getting a solver will help you a lot when you start grasping these things on the surface.
By studying theory and understanding how GTO/solver "thinks", you will figure out spots yourself without having been in the same exact spot before.
If you have time on your break, these are fantastic things to study.
