frustrating hu session

Just played this fish HU for a pretty long time and lost 3.5 stacks to him (we paid 50bb rake wtf).
I'm pretty sure I had an edge on him.

First stack

I lost to this kid, I think you get my drift on why I think he was bad. Basically I'm never folding that turn when I pick up 15 outs and he leads weakly like that.

Cooler

On that flop there is not really much I can do tbh. He has weaker As and draws here that I'm ahead of plus he calls reraises very lightly.

Coinflip

Meh was a coinflip and I guess a beat if he calls my 4bets with t6s.

I basically kept on grinding up my stack and then losing some medium sized pot. I also value owned myself twice, I need to beware of that, I could be betting too thinly versus some of these guys.

Hu is a lot of variance so I basically need to put in some more hands to let the big numbers kick in. It is also very player dependant and requires a lot of adjusting to situations, which I like, because this is where you can really gain an edge vs a weaker player.
