Gravity Chess Tournament

Welcome to the First International Gravity Chess Tournament! This competition will decide the title of the World Gravity Chess Champion, along with excellent prizes for the top three finishers. Come claim your spot in the annals of history!

Dates

Rules

The tournament will be run in a round-robin style, followed by double elimination. Thus, each competitor can expect to be somewhere in [11, 14] matchups.

Due to the fundamental asymmetry of gravity chess, each "matchup" consists of two games—one where you play as white, and one where you play as black. Winning both games gets you a score of 1; losing both games gets you a score of 0; winning one but not the other gets you a score of ¹⁄₂.

Over-the-board games are great, so long as there's someone recording moves. Alternatively, you can play on my amazing Gravity Chess server!

Are you just doing this to get more data for some twisted analysis of which side has the starting advantage?

Well, AlphaZero is currently playing itself on my laptop way more times than this tournament can have total games, so that is unlikely.
