The rules of Chomp are simple. Players alternate turns, on each turn removing a square, as well as all those that are above or the the right of it (in other words, all squares with both coordinates ≥ it). The goal is to avoid having to eat the poison square (the one with the skull on it).

The current state of the board is:

The three highest options on /JosephNoonan/manifold-plays-chomp-third-move were (4,1), (2,2), and (2,1). To choose between them, we are using these conditional markets, asking whether Manifold will win, given that each of them are chosen. When this market closes, the option with the highest average probability will be chosen as the next move, and the other two options will be resolved N/A. The chosen move will resolve to YES or NO once the game of Chomp is completed, based on whether Manifold wins or loses.
