Talk about more than just the hands. Talk about the game. Talk about the things you need to do to beat the limit. Talk about common mistakes and what to do, and what not to do. (You can edit this in via a voiceover.)
I really feel thats missing in alot of the vids posted on the site. Its usually just "fold this" "raise this" and alot of silence.
p.s.: This has already been done by another pokersite I know of, have you seen it? You need to beat it. It's called "through the limits" and its a total of six clips. NL25, NL50, NL100, NL200, NL400 and NL600.
