I don't like PF not the hand you want vs these guys
I understand the thinking behind it, but I'm not crazy about the isoraise w/46s, even on the button, especially against fish who won't fold to a semi-bluff.
Definitely don't shove the turn, there is no fold equity against players like you describe, they'll call with just about anything.
Good advice already ITT.
Sounds like a juicy game. Enjoy killing it next time.
