The very first hand was 3 handed, and I thought it was a decision that required at least a moment of thought. Probably a no brainer for many of you.

The next 26 hands are me versus a totally clueless, and therefore unpredictable player. My goal was to generally reduce variance and not push thin edges, thinking that this player would dig their own grave soon enough. However, villain seemed to understand aggression despite not understanding PLO8 mechanics, and I suspect I was getting outplayed here.

Again, 27 hands total, so bring the popcorn.

I think that was well played on the whole, pretty obvious shove on last hand imo. I loved the way the first hand was played when three handed. I think you might have missed a few spots for steals when you had position both pre and postflop including on the river but as you say you couldnt know if he was liable to look you up so safety first, and those steals probably wouldn't have amounted to much difference in stack sizes anyway. It was a bit iffy when you had the nut straight with the 89 - I think it was possibly wrong to take a card off and I would've got it all in on the flop, but I probably woulda folded that one preflop - even heads up its hard to scoop with that unless you win uncontested.
