I like your line. Those half pot cbets when we already know he has Aces are so damn weak. If he called you down with nothing but AA just take a note, I would say that most PLO10 players would lay it down (unless hes some big fish of course, in which case bluffing is already bad on the flop)

Old hand i know, but this is a easy x/fold otf in a 3bet pot oop readless.

Yes as a default. But i want some blfing hans agaist well defined ranges, and this was the prototype of that.

he just can't call here EVER.

Apparently this is not true, as he did.
Once he calls the flop, your folding equity goes down. He might have AA76, AA88, AA79 with flush draws or just bare Aces and he doesn't like to fold it. The thing is that especially when he calls pot bet on the turn he is not calling to fold the river often.

Flop raise is fine but after that I would shut down against relatively unknown in PLO10.

He called 4,9 and pot was 8

This WTF bet with no but blockers OMG

Had i had blockers, the outcome would be the same. These spots are +ev raises even without blockers against a well defined range i am sure of that because i analyzed many spots with pokerjuice. The mistake i made was thinking that villain is surely folding AA here (calling is really bad obviously) and apparently i did this line against an "acelover" guy, but i noted and labelled him, and i will be even more selective with who i will do this play against at plo10

Today I did the same and opponent called down with JJxx. Don't worry about it, make a note and start printing money in future.
