I have been watching a lot of Fydor's videos lately, and while most of them seem very basic, I am learning a ton from them.I had a discussion on AIM the other day with him, and he said that solid ABC poker with some adjustments according to opponents is all you need to beat the "lower stakes" games.At what you stakes do you need to start acquiring further skills? He was unable to tell me this because he hasn't played the lower/mid-stakes regularly for some time now?If someone learns a solid ABC strategy and learns some minimal adjustments to various opponents, what stakes level will this take them to?
