I wrote here before (can't find the link) about his mental illness. If I recall correctly, I made the similiar point that if you are known to be off balance, then probably just about the worst way to spend your time would be as a professional high stakes poker player. Hell, I'm mentally well balanced, at least that is what the voices in my head keep telling me, and I sometimes get really f***ed up in the head when I take a bad beat. Up the stakes and it could easily send Dutch over the edge.
