Standing after 49 rounds

1. [Stockfish 100218] 34.0/49 (743.00)
2. [Houdini 6.03] 32.5/49 (727.75)
3. [Komodo 2012.00] 29.0/49 (661.75)

6. [Andscacs 0.93] 22.0/49 (497.25)
7. [Fizbo 2] 19.0/49 (421.00)
8. [Ginkgo 2.03] 11.0/49 (281.00)

Too bad only the top 2 engines go on to the superfinal.
I would like to see 4 then 2.
The differences look significant until you look at the head to head results, which are extremely close. It may be that (for instance) the SF tweaking of contempt allows for far less cautious play against much weaker engines giving more points. But this may or may not lead to better play against the top engines (only Houdini has no losses). Against the high-end competition, K and SF have similar records. The no losses for H is likely just a probability anomaly. Not enough games to make an accurate statement.
I get the perception that Fire is not as strong against the top 3 but there are not really enough games for that. Too bad Shredder won't play.

There won't be much of a superfinal. The latest Stockfish is disgustingly strong. Stockfish development is alive again. This will be a very easy superfinal for Stockfish. Frankly, Komodo did not belong in the last superfinal. It barely squeezed its way through. "Drawfish" aka Stockfish with contempt 0 has been solved leaving its only real weakness in these tournaments left in the dust.

Andscacs win over Komodo was stunning: it won rook/pawn ending without tablebases! Just after somebody wrote in chat: Andscacs can't beat top 3 engines without tb .

[Krzysztof Grzelak]

You have to face the truth. Komodo is just weak. A new version has just been released and unfortunately it is still a poor program. And for what people pay 100 $.

2/3 of Premier Division are completed up to this point. It looks like Stockfish and Houdini have a good margin over Komodo. Fizbo and Ginkgo continue in the relegation positions. In general, we can see a difference of more than two points between any position and the position just below it. Follow live games in http://tcec.chessdom.com/live.php

Obviously xx. g4!(pawn) is almost always win for SF and Houdini .

[JamesTCEC]

Stockfish & Houdini are in qualifying temporarily to superfinal, Fizbo & Ginkgo will be relegated to 1st Division if they stay in the bottom. Still 21 rounds to go in this Division. Follow live games in http://tcec.chessdom.com/live.php

Correction: Andscacs is 5th and Chiron is 6th. All the numbers are right.
