Günther already mentioned, that this was almost average. Are you using book
learning (I know, that you use position learning)? Position learning alone will
not affect book choices at all. Is Aristarch using book learning?

Thanks, I fear I will not find the time, to look over all this carefully. It
might be interesting for a book cooker. One would then probably also want to
have a comparision to results with longer time controls, before making
conclusions.

Günther, yes, some of those look rather extreme. Feel free to look at the games
and send comments :-)

Cheers,
Dieter
