Winter perhaps overestimated its attack a bit?! Fab played it cool anyway...

I also think that knight sacrifice was a bit adventurous by black...

That was a fantastic game! Perhaps a bit too adventurous by Winter indeed, but also well defended by Fab.

Thanks for including Winter in your tournament!

Nice tournament! I will follow it with big interest! Is there a way to watch the games while they are being played? Or is it atleast possible to see the played games somewhere? Really didnt except Koivisto to beat Lc0 :)

Halogen is trying his best in a very tough company :shock:
Very tough field indeed :oops:. Halogen dev already +70 points to Halogen 8.1 so it will be back with a vengeance soon!

No live stream so far :oops: I will upload a pgn file with all played games after round 16 and after the whole tourney (in very short format: just a move list). Next update will be in 2-3 hours (games are already played).

Koivisto is going well but there is a problem: it lost 3 games on time (each in over 100 moves) and one game by ''illegal move''. All these games were replayed. Unfortunately, I haven't saved a log-file of that games but I can produce it next time if you are interested.

Of course. a CPU version of Lc0 is playing here but still a nice win by Kiivisto :D

Halogen is doing much better after round 16. I will show the updated table very soon.

All Marvin 4.0.0 games were replayed with MultiPV = 1, LogLevel = 2.
Koivisto 4.0 lost 3 games on time, they were also replayed.

Standings after round 16:

Games would be more interesting as pgn with eval/depth+time as usual (even for very fast tc), also for finding out bugs
in either the engines or the tournament setup. Just zip/7z the files.

I wonder why you first had to set Marvin to MPV=3, because it would not work normally at your side and now it suddenly works
with MPV=1 as it should?
Also if there are time losses by engine bugs they should count, or do you already think it was not due to the engine?

BTW, why do so much engine say 'resign' in your game file, uci engines usually cannot resign at all?
