I think my fundamentals are good enough for the quality of villain I'm up against. Could they be better? Of course. I'm pretty strong when it comes to the maths fundamentals. I'm capable of estimating my equity to a reasonable enough accuracy in the time given, and I'm not terrible at assigning ranges to people based on the limited information I have. I'm a long way from perfect, but it's a relative standard... how good am I compared to the people I'm sat with? People are certainly not assigning me a range, because the same people keep calling their 66 and KQo to my shoves.

The theory side of things, idk how good my fundamentals are to be honest, all I know is that my opponents' standards are sufficiently terrible that I can easily exploit them.
