God rest his soul. He was mine, and many friends hero throughout my snooker playing youth. As others have mentioned, he obviously became 'star struck' and ‘troubled’, early in his life and basically couldn't handle it. Look at the support people like Robbie Williams get nowadays, and still they falter! Alex was as big (comparatively) in his day, but with zero support or advice.
I truly felt sorry for the man when he was alive, he could, with proper management, have had a magnificently rewarding and enjoyable life!
I can't say I feel a tremendous loss, however, the man has certainly influenced my life, given me inspiration as a young lad and left me in awe of his indisputable talent.
As with Oliver Reed and George Best, an iconic alcoholic has died. A victim of his own success, there is so much to be said for living a 'normal' life with a normal wife and kids.
RIP great man, faults and all.
