Komodo won the first game of the match and currently leads +2-0=14, with an average of five games played per day.
Since then the world's top two engines, Komodo and Stockfish, have played another 30 games with a result of +2-1=27 in Komodo's favor. Komodo scored both of its wins with Black, bringing the total score of the match to +4-1=41, with 54 more games to be played.
The week's most memorable game was undoubtedly no.22, where Stockfish seemed to throw away a huge advantage with White in the following position.
TCEC Season 8 Superfinal, game 22
Stockfish - Komodo
After 63...Qd6-Qf6
The position was discussed at length in the FishCooking forum (see my recent post Chess Engines : FishCookingfor background), especially From +26.13 to 0.00 in two moves(11 November).
What happened in game 22 of the final? Stockfish's evaluation was steeply raising, until at move 62 it evaluated its position as +26.13. Komodo agreed to a degree by evaluating it at +4.22. Then two moves later both evals had dropped to 0.00, and it ended in draw. Rather unusual, I would say.
