Although the setting was a simultaneous exhibition, Lasker's opponent, Max Demby, was not a typical hapless "N.N." victim. Some 20 years earlier Demby won a tournament in Panama, and close in time to this game he was one of 4 opponents to draw against George Koltanowski in a 10-board blindfold exhibition at the Manhattan Chess Club.} 1. e4 e6 2. d4 d5 3.
