I just saw a better-than-professional-quality amateur instructional chess video by Patrick of the excellent Chess for Blood blog, discussing a game he played that began 1.e4 c5 2.Nf3 d6 3.Be2 Nf6 4.c3. Definitely worth a look, and an inspiration for others (including myself). I wrote a Review of ChessLecture.com a while back in which I touted the value of chess on video. Patrick's efforts may signal a trend toward more free video chess content, which would be great for amateur players without a lot of money to subscribe to online chess services.
Of course, it may not be so great for chess professionals. The You-Tube revolution is just one more thing that will make it more difficult to make a living from chess. After all, with so much free content out there, why pay for it? In the end, we amateurs might be driving down the monetary value of chess content. Just a thought.
