I am a midstakes HU reg, and HU is my best game. It's also the game I played the most, I believe. I think I've had a fairly successful career, and I try to stick to the things that I'm good at.
I write a lot of notes, about anything from timing tells to betting patterns and so on. In HU you get to play a lot of marginal situations, which should arguably be good for your poker skills.
While I think that to know the exact stats is not as important as in 6max, I can't deny that I've been neglecting this part a bit. So I'm looking for someone who is good at exactly that, stats.
I am not "picky" about the stakes I want you to play, as long as you are dedicated to the game and want to improve.
