Friday Night

So there I was at the stroke of midnight, contemplating the four-knights opening by the dim glow of a flashlight, ears popping under the extra five pounds per square inch of pressure.

On Friday night, Dan (who you may remember as the Robot9000 bot author), Finn and I invented midnight underwater speed chess.

A nice feature is the naturally-enforced clock.  You have as much time per move as you have air in your lungs. Protip: don’t use a glass set.

Now we just need to combine it with chess boxing.
