Yes this season SF unbeaten streak was only 6 games - bad regression . Seriously I give it 90% chance of win this Division with working contempt. Stunning that SF won season 9 without working contempt!

[JamesTCEC]

First double round robin (14 rounds) of Premier Division has been played . Stockfish is leading with 0.5 advantage over Komodo (2nd) and Houdini (3rd), Fizbo and Ginkgo are in the two bottom places (relegation zone to 1st Division). From now on, all the games will follow openings from Catobase.

Stockfish contempt is working really well (score vs weaker engines):

1=1 ==11 11=1 111= =111

[JJJ]

Indeed, with contempt Stockfish has the last piece of strenght he needed to crush opposition and be the true number one engine.

[JamesTCEC]

1/3 of Premier Division has been played (28 rounds). Stockfish (20) is still in the lead and Houdini (18) is second while Komodo (16) is in the third place. Ginkgo (6.5) and Fizbo (10.5) continue in the two bottom places while Andscacs (12) is 6th. Still a lot of games to be played and anything can happen.

One of the last two tables must be wrong because Ginkgo has now less points than in round 21?

I think the previous table had Fizbo 2 and Ginkgo 2.03 names reversed.

Correction on the standings:

7. [Fizbo 2] 7.0/21 (67.50)
8. [Ginkgo 2.03] 4.5/21 (47.75)
