A move's percentage is the computer's best estimate of how likely the player to move is to win after it, counting a draw as half; the moves are ranked by it. A move's line is how the computer would play on from there for both players, searching each turn, and the estimate is two parts what the first of those searches makes of the move (searched) to one part where the line ends. A move that wins or loses by force, which the computer proves by looking 3 turns ahead, is a win or 0%. At a glance is the network's first impression of a move, without searching. Squares are named as on a chess board: letters are columns and numbers rows, with A1 bottom left. Keys: K and C choose a kitten or a cat, ← and → step through a line, and Esc goes back to the puzzle. Puzzles you solve at the first try, without a hint, are remembered in this browser and don't come up again; the others can. Reset progress
