In 1977 Nicklaus shot 68,70,65,66. Watson 68,70,65,65. They After two rounds a bunch of guys were in the race. After three rounds it Nicklaus v Watson for the Claret Jug. The last two rounds they shot still may be the best two rounds between opponents that I remember. Mickelson's third round might be the best scrambling round ever played. The last round this year has few peers.
