The YouTube channel that is hosting the video made by Brian Wall is managed by someone else, but the videos themselves are definitely unique and well done and Mr. Wall talks about how a 1500 rated chess player defeated a Grandmaster in a Chess Simul exhibition using the trapping line:
Fishing Pole: First Blood pt 1
Fishing Pole: First Blood pt 2
Brian Wall also has his own web page that you can visit HERE. I believe the site is still under construction.
