Baseline Bots

Bot	Description
trout	Keeps track of a naive single board state with basic, semi-random sensing of unoccupied squares and makes moves with Stockfish.
attacker	Senses randomly and tries to capture the opponent king with a classic 4-move "mate" or by attacking with a knight.
random	Senses and moves randomly.
Oracle	Keeps track of all the possible board states, sensing to minimize possible opponent states, and makes moves with Stockfish plus heuristics.
Marmot	Uses a modified Monte Carlo counterfactual regret minimization algorithm for sensing and moving that leverages online outcome sampling and a heuristic state evaluation.
