Making too many moves vs unknowns imo. Villain is giving you great odds pre, just take it.

As played, folding the river. There's like no air anymore.

I thought this might have been a hand where FPS has got me into trouble. By posting hands when I do dumb shit like this, it should hopefully help me stop doing it.

Fold. I really don't know why you made him re-raise before the flop with KJ, when like you say the villain is unknown and it's only 2nd hand at the table. Maybe it would be better to wait better hand to make that raise. However, my opinion is that more than sure the villain has Ax, so it would be better to go fold.

4betting a min-raise from a confirmed fish (less than full stack,plus he min-raised) for anything other than value isn't going to be a winning play imo, but calling the min-raise pretty wide is going to be fine.

C/f turn and river as played.

Check the flop if you want to rep the ace.

Uh this is 50nl? wtf is everyone doing? I've no idea what this 4bet is about, seems like you're trying to stamp some authority on the noob or something like that. Just take the pot odds and try to cooler his dumb 3bet. Flop bet seems like it's setting money on fire too, I don't anticipate many folds so we're hoping to bink a 4 outer to cooler him on the turn? Is that the plan?

I'd call pre c/f flop c/f turn c/f river, seems ldo really but obviously it's not because I'm microdonking and you're not.
