i certainly didnt write him off, i watched the first 2 videos, the short powerpoint thing and the session at 2NL.. he specifically says that his strategy is aimed at beginners and its deliberately dumbed down so be as simple as possible to turn a complete baffoon into a 2NL winner.
also says something along the lines of "to all the 2+2ers, dont call me a retard, i know this isnt 100% optimal for higher stakes" ...I gather his lessons get more complicated in the next set of videos
