Reconnaissance Blind Chess: An Unsolved Challenge for Multi-Agent Decision Making Under Uncertainty

Reconnaissance Blind Chess (RBC) is like chess except a player cannot see her opponent's pieces in general. Rather, each player chooses a 3x3 square of the board to privately observe each turn. State-of-the-art algorithms, including those used to create agents for previous games like chess, Go, and poker, break down in Reconnaissance Blind Chess for several reasons including the imperfect information, absence of obvious abstractions, and lack of common knowledge. Build the best bot for this challenge in making strong decisions in competitive multi-agent scenarios in the face of uncertainty!
