Me & the rest of the baysians trained eachother. However, I learned mostly from myself.
A habit I developed early on in my smash career, when I lost tournament matches (usually by a landslide), I'd ask the person I lost to how to beat them. Amazingly, a lot of people actually tell you how to beat them. It seemed counter-intuitive to give your weakness away and everything, but I find it both beneficial to the community AND to yourself to tell your weaknesses.
King taught me how to beat him, and I've told many people how to beat me.
