I'm not sure that OP's request was actually really even answered here.
So many suggestions to watch 'tv poker' where commentator is an analyst (obviously). I REALLY don't think this is what he's talking about here at all. Reply towards Stoxpoker, etc. I'm sure is much more along the lines of their request (but looking for one's that are 'free').
Yes there are LOTS of free ones out there on the internet.. BUT most of them are completely CRAP!!!! Every kid & his dog are putting out commentated sng's, claiming to be 'winning players' but if you even watch them play a hand or two you'll find you're disappointed and have just wasted your time again.
Suggestion for MartySmith's videos (yah.. he's got a series of videos for SNG & MTT play..... all are free but he's always pumping some software while doing so). Other thing about Marty & his vids., I REALLY don't agree with how he play STT's..... guess what.. his stats. don't agree with how he plays either (he runs like crap... why learn from crap?). His vids. would be of some benefit to a complete noob, although I think they'd also potentially instill some bad habits.
So... how do you find the 'GOOD' 'free' commentated poker training videos online?? Good question. First off, try to find out who some of the better players are who are also good at coaching (guess what... generally speaking these ones won't be the 'free ones', lol). Once you've gotten a short list of names, your search will be alot easier. Also obviously looking for someone who puts out vids. that are pertaining to the buyin level you're playing at. Someone like Jennifear is a great coach for low stakes SNG's.
What kinds of vids. exactly are you looking for? SNG lowstakes (ie. $16's & under), MTT's, 6-MaxNL, FullRing, etc...
If you want to try pm'ing me, I could probably find you a few for the type of game you're interested in.
GL on the tables!
