Dragon by Komodo Chess

[Madeleine Birchfield]

Just read this on Twitter.

Matthew Sadler is wrong; Komodo hasn't been updated to the Dragon version for the FRC2 bonus according to that website.

Hikaru Nakamura is an obvious one; he played against Rybka and Houdini without handicaps a decade ago and managed to draw both of them. His streaming platform on Twitch would also bring more interest into computer chess and your new Dragon engine, and he is affiliated with chess.com.

You would think that the stars are aligned with all those points ...

A short test Dragon NNUE. You still have problems with time, unfortunately the same bug is in Komodo.

The file shows a ten game match with Lc0 with a score of one win each and eight draws, and the sole loss was by adjudication, not time. Could you please explain what you think is the problem with Komodo or Dragon time management? It's not obvious from the file.

Please clarify does Dragon NNUE performs better in shorter time control Blitz, or the other way around using standard time control?

I don't remember these games from a decade ago. Could you remind me of the details, like where played, how many games, time limits, score, hardware, and any other relevant factors?

We have released Dragon by Komodo Chess at komodochess.com today. It uses the NNUE technology (but not the code) developed for the game of shogi. The improvement in strength over the latest standard Komodo, version 14.1, is enormous, roughly 160 elo on four threads, 190 elo on one thread, based on 2' +1" matches.

7000 games testrun of KomodoDragon 1.0 is finished. Versus 7 engines, I can confirm that progress...
Look on my website:

Still about 80 points behind a similar current Stockfish. Not bad.

At 5m+5s on a 32 thread 2950x. Dragon is doing much better then 80 Elo. Very good for the first release of Dragon.

Mark L. asked my to change the default setting for hash memory from default. I do not know if this changed the results. Default was 64, and was changed to 512. The suggested best setting for this many threads.

Here is the results playing the best Stockfish.

Dragon by Komodo Chess vs Stockfish 101120 (TC=5m+5s)

With 198 games played so far. Dragon vs Stockfish 101120 +6 =172 -20. 46.5% TP = -25 Elo.

I read on TCEC that they have NOT received the Komodo Dragon version which they ae interested in testing it on FRC very soon, I guess that Mr. Kaufman has NOT sent them the program yet.

No one should be surprised if Dragon beats Stockfish in the TCEC Tournament.
