you've mentinoed some good ones.... gripsed has tonnes....
i like:
The Poker Bank
greenbeanvideos
BlackRain79Poker
there's a Brazilian guy, very good at hand reading. He's name is Gustavo Sampaio, for those who knows English, worth a try.
JCarverPoker on twitch is also a good one!
My favourite poker guys in youtube is grispedpoker, felix schneiders. Also in youtube are many bad stuff, you need to choose which is good for you and which is bullshit.
I follow a couple of poker guys on Youtube and watch everything they put out and much of it over and over.
Who are your favorites to watch on Youtube?
