You tube piano tricks

I have been listening to some youtube piano videos, and I have noticed that one of the qualities in the best ones is that the player knows how to play, rather than demonstrating a technique or sequence of chords without any real jazz feeling. It might seem obvious but that's my guarantee that the player will not steer me in the wrong direction. The three best instructors I have found are Marius Nordal, Aimee Nolte, and Hal Galper. When you hear them play there is a level of conviction there, even when showing a simplistic lick it will be with the right feeling. There are other guys on the net who play woodenly, whether because they think they need to to teach, or because they actually aren't very good.
