It is sad that he can't do more with his life and I wish him the best of luck in the future.
However, strong blitz players don't impress me (unless they're also good at standard). I certainly won't consider him a "Chess King" even in the most abstract sense. Blitz is poorly representative of chess strength and can hardly be called chess at all. Chess is considered a thinking man's game and blitz is anything but that. Blitz game is mostly a test of how well one knows a surprising pet opening, how quickly one sees simple threats and how well one can manage the very little time available. The quality of the opening makes little difference as long as you can play it quickly and, if possible, surprise your opponent. The Grob is perfect for blitz. Strategy, while very important in normal games, is almost irrelevant in blitz. You may try to exploit your opponent's backward pawn or many pawn islands, but while you waste time on that, he's setting you mate problems and making you work hard to not lose a piece. You may get a better position, but it doesn't matter because you spent too much time trying to solve his problems. In blitz, any move is almost always better than a great move that takes you a whole minute to make. Time rules over quality. Endgame technique? Forget it! In Blitz, you're lucky if you don't run out of time or get mated before the endgame. If there is an endgame, it is still just a battle of moving as fast as possible without losing and one side usually has such an overwhelming advantage that it is just a massacre. While the better chess player is the one who tries to win often playing beautiful moves, in blitz it is usually the one who moves fast and avoids loss. That Murphy could call his Blitz games works of art is very surprising to me. In blitz, the best parts of chess, often requiring real high level thought are lost. Blitz is akin to eating at McDonald's in five minutes compared to a high-end restaurant.
Of course, blitz has its place. It is great for helping one get a basic feel of some openings. It may be helpful in making one more quickly spot basic tactics and in general, to avoid huge blunders. And of course, it's fun to play a quick frantic game. I play blitz several times a week myself. However, I don't consider blitz to be good chess or a real show of skill.
