disclaimer: don't play much plo
Preflop is a bit loose though right? Especially this deep oop seems like a fold pre.
Flop is obviously standard and I agree with leading turn. The problem is 3-way on that board honestly one player will have QJ a lot and there are a ton of strong draws that won't fold so both of the other two players shouldn't be bluffing
much at all. I also think if they're not that good at plo that if you bet they could raise naked QJ and you could get it in freerolling a good amount of the time, obviously sucks when you're up against QJ+better FD though and I don't know enough about plo preflop ranges to know how often you're freerolling vs. getting freerolled if stacks go in.
River I think betting is spew pretty sure against most good (especially live players who tend to be nittier I think) players ch/f is actually the best line. If you perceive them to be super bluffy I guess ch/c is better but one of them is actually going to have a better flush a decent amount of the time and when they don't they're just gonna fold. It's just that even fish probably love playing AxXxXX a lot and might have close to all AsXsXX in his range. Again I'm not sure about preflop ranges just sorta throwing out some ideas. I'm pretty sure about turn being a bet though, that's the one street I think I'm confident on.
