Thanks for testing SlowChess.
The result is actually better than what I was hoping for (around +50 Elo from v1.6) Looks like part of it is an outlier result against Nirvana Chess.

-Jon

Out of curiosity I looked at some games vs. Nirvana and noticed some strange behaviour by Nirvana.
Either it has a serious time management bug (found no traces of that bug though in talkchess messages yet),
or it played by accident with asymmetric time controls, or the GUI sent time in an unexpected way?

Edit:
Even not taking book moves into account (which normally should be known as a serious bug meanwhile after all the years?)
does not fit really to that behaviour, as there were 8 book moves and avg. thinking time at this tc would be ~12s, but even
with around 96s saving for fictional 8 moves more would still be off by a big margin?

Anyhow, Nirvana had still left 211s from total 480s until the first move period (real tc was 40/480).

Here is game 1 from that 100 games match vs. SlowChess as an example
(pgn transformed into something more readable and what can be fed for converting into my google sheet stats):

[Guenther]

I did a test game which simulated the same conditions for Nirvana 2.4 (4 cpus, same tc, 8 book moves)
under CuteChess and received a very different behaviour. I stopped the game after 40 moves, after
it was clear that the time management was 'ok' in my test.
31s left over with move 40 instead of 211s in the CEGT game, which is not great, but not insane either.
(meanwhile I looked at several games of the match and they are all similar in that buggy behaviour)

The stats and graph are added to the same google sheet as in my first post.

Hi Guenther,
thanks for looking after these games and showing that something was not ok.

I did a look too at the games and I found the reason of this result. Nirvana Chess 2.4 played on 4CPUs - I wanted to make a match against the 1CPU version. I accidentlly took the wrong engine. As this match was not the only one on the 4CPU PC at the same time Nirvana could not use all 4 CPUs and therefore such funny results occured.
I think the best way is to repeat this match and delete the older games on our list. Hopefully I can do this before our next update.

best wishes
Werner

Thanks for the info Werner. I am a bit surprised that this scenario had such an effect.
Normally I would expect the opposite effect of losing on time here and there, or reaching too low depths,
but not playing too fast.

Now the correct result:
SlowChess Blitz Classic 1.7 - Nirvana Chess 2.4 x64 1CPU : 43,5/100 19-32-49
