I am mainly a MTT reg (can beat 50 ABI MTTs with meh ROI% over 20k games). I am currently learning NL50 6max as a way to improve my MTT game and not get crushed when i play 300+ BI MTTs or EPTs in the future.

I am playing non-zoom NL50 on stars. I wanna know how GTO the 50nl regs have become. Are they close to perfectly balanced preflop vs regs in opening n 3betting?

Also, is the below range construction fine?

Also, i d k wat to do if i 3b AKs and get 4b by UTG, flat 4b or fold or 5b vs a GTO-ish reg?

Also, below is too tight right in 50nl? We can open wider exploitatively?

UTG 16% AA-55, AKo-AJo, KQo, AKs-A2s, KQs-K9s, QJs-Q9s, JTs-J9s, T9s-T8s, 98s, 87s, 76s

65s-63s, 54s-53s, 43s, 32s

Anyway, im seeking for a nl50 coach (at a low price <100/h) or any study partner. I rly suck.
