Hey all, I've been working through FTGU PLO and have recently focused in on my pre-flop game. While I have been able to use the course as a good way to understand the core concepts, I'm having trouble 'checking my work' when looking at old hands. In the videos Emty uses MonkerSolver to get a GTO range, but I don't have the PC to run sims and don't know where else to get pre-flop GTO ranges.

So when I'm reviewing my sessions and I want to know if I played a hand correctly pre-flop what should I do? Just go on my FTGU notes, or should I invest in something like the PLO Matrix or the PLO Preflop Helper from MasterMind?
