What Should Have Happened?
Under this title chess.com ran 56 games (from the position in which Carlsen offered the draw) on the top chess engines in the world, with these results:
White wins: 3 games
Black wins: 27 games
Draw: 26 games
The top eight chess engines in the CCC played a 2x-round-robin tournament starting after move 31 of the world chess championship game 12. The time control is rapid chess, 30 minutes plus five-second increment.
The programs were run on Stockfish, Komodo, Ethereal, Fire, Houdini, Andscacs, Lc0 and Laser.
Stockfish won the tournament one point ahead of Komodo.
