I really enjoy watching Keith's matches. They are a breath of fresh air to see someone with more natural/personal/unique mechanics in this era of robotic clones. He is proof you can play to an extremely high level and not follow the "proper" playing form. I don't mean this as any kind of disparagement either, I genuinely love watching unorthodox players that can play to a high level. I wouldn't mind hearing about his unorthodox style and how he came up with it.
I'd definitely like to hear his story, stories of things he saw and other players of that era. I don't know of anything specific I'd ask but I'm looking forward to the podcast.
