How the games break down between human and computer players.
Plies per finished game. Nothing is captured, so length is driven by how fast a king gets cornered.
The square the losing king stood on. Back-rank squares dominate: a king steps off e1 or e8, the backtrack rule bars the return, and the rim leaves only five neighbours.
First move of each game.
Every player, human and computer. Rate counts a draw as half a point.
Row's score against column, as a percentage. Read across a row to see who that personality beats.
