His stamina is undoubtedly a major strength. And this is allied with his uncanny ability to keep pressure on his opponents in even the most apparently even positions. This pressure mounts and the psychological impact is devastating because his opponent knows that the most tiny inaccuracy will be noted and he will immediately be under still more pressure. This pressure to play perfectly is gruelling over 6-7 hours. The thing that most people don't appreciate is that a player like Carlsen, even against the most phenomenal opponent like Anand, is like a python, the slightest pause for breath, the most minute inaccuracy, and the coils tighten. It's suffocating.
