the content is very interesting for sure. Especially application wise in a game, how to, and how not to 3bet the best.
As always it's so situation dependant/player dependant that it's difficult to come up with crystal clear hands/plays that are best. I somehow got the vibe from the bullet points that 3betting is always good, with any hand, when you went through the different types of hands. I read it again, in more depth a second time, and got what you meant a bit more.
the 3 hands that are good to 3bet categories: maybe give some examples here since imo no1 and 2 are very similair(from how u describe them) and no3 im not sure what you mean.
the when better to call section is good, easy to understand and has a clear example(Patrik)
the content is as I said good. I feel it is so much info though
also: deficits of 3betting: id say you need to handle variance VERY well, to be able to try this playstyle out in a serious way. Are there other factors to consider? good regs adapting, exploiting easily?(havent thought about it myself... maybe position is even more important here)
