I assumed "sure... the real reason was drugs or alcohol", but apparently neither were involved. Is it bad that I'm really curious over what the move was... what move could cause such a reaction, would it happen to one of us if we observed the same thing, like that Pokemon episode caused those epileptic seizures? Probably it was over something stupid like en passant or whether a king can castle to the queenside... also I'd highly suspect that something like antidepressants, which can cause homicidal tendencies, were involved. Maybe steroids, maybe the Bongcloud attack who knows.
