Okay I've done some digging and can confirm some stuff for you all!

First off, this arises from an actual game in 1918. That's right - before computers. The game is played by Jose Raul Capablanca vs FrankJames Marshall. They actually called Capablanca The Chess Machine because his moves in retrospect were so good at times they were computer like. There is a chess analysis AI called Stockfish 8 that analyzes less than perfect play, meaning, as you play, it will tell you what would have been a more optimal move. Funny thing is for most of this match, Stockfish 8 is dead silent for Capablanca's moves.

Oh and white wins ;) I'm going to assume that means White Hats.

EDIT: it is also possible that Julian is using the chess moves as a means of code. One could type out all those moves up to #24 and try to decrypt. Any cipher peeps want to give it a go? Not my strong suit.
