The Chess.com Computer Chess champion Stockfish defended its sixth straight title last weekend as it bested the machine-learning engine Lc0 in a heads-up match that went the distance to the maximum number of games.

Stockfish took the CCC 6: Winter Classic championship belt after a solid 101.5/200 showing in the final, which was played at a time control of 10 minutes plus a 10-second increment.

These two engines move on to CCC 7: Blitz Bonanza, heading a field of 24 engines in the first stage of the tournament. 

CCC: 7 Blitz Bonanza is in progress now as the round-robin follows an escalating order, with the top seeds playing last.

Stage one of CCC 7 is a 24-player round-robin, where each engine will play every other engine three times as White and three times as Black. The top four engines from stage one will advance to a 100x round-robin final stage.

CCC 6: Finals PGN Download and Selected Games:

Lc0 showed its unique, almost-human capacity to torment its opponent, taking nearly 300 moves to checkmate Stockfish while up a rook. Does Lc0 "enjoy" being in a winning position for as long as possible, or is it just playing it safe with every move?

Stockfish, on the other hand, demonstrated its trademark brutal efficiency, turning a small advantage on move 35 into a checkmate just 10 moves later.
