"The chess story of Mikhail Tal is about the act itself of straining against the leash of limited human imagination to create mammoth combinations on the chessboard. During his games, Tal wished to go where no chess player had ever gone before, choosing the middlegame as his metier for creative expression. He burned energy profligately. A chain-smoker and a heavy drinker, Tal pulsated nervous energy, pacing like a caged tiger in between moves. And as a young man with those famous fierce, hooded eyes and that imposing hooked nose, he bulldozed all before him."
