Bobby Fischer's 21-move brilliancy

Bobby Fischer creates a chess masterpiece in only 21 moves against Robert Eugene Byrne, an International Master, at the 1963/1964 United States Chess Championship, held in New York. At 20 years young, Grandmaster Robert James Fischer was already among the world's very best chess players. In this brilliancy, Fischer demonstrates how to inject multiple imbalances into a highly symmetrical position, how to properly highlight these differences to benefit oneself, and how to accurately assess the true value of the pieces as they rest on the board.

The Infinite Hotel, a thought experiment created by German mathematician David Hilbert, is a hotel with an infinite number of rooms. Easy to comprehend, right? Wrong. What if it's completely booked but one person wants to check in? What about 40? Or an infinitely full bus of people? Jeff Dekofsky solves these heady lodging issues using Hilbert's paradox.
