I have GTO+ as a solver and do a decent amount of work with it, flagging hands that I don't understand and then doing solver studies with the ranges to better understand where I'm at. I feel like I really am starting to understand where I am at NL50 and have a pretty good idea of GTO play and exploits.

However I'm completely lost in multiway pots, and I don't know how to get better without a solver that can go multiway. Any tips and tricks for getting better? I'm usually against weaker competition when stuff goes multiway, but feel like I'm playing fit or fold waay too often. I've included a sample hand where I'm just totally lost.
