Does anyone have any exercises they have found useful for understanding equity in multi-way pots, or just in general? Would like to spend some more time using PIO and studying in general, but feeling kinda lost on how to use it effectively. Or videos you recommend?

Guess I should mention. I play 1-3 live and played 100nl online for last few years w a reasonable Winerate(11/100). Still feel like there’s a lot of holes in my understanding however and kinda been on a plateau for a while and not sure how to get past it.
