We have two new excellent entries in the Open Ranking !

Daniel Reist managed to draw level with the previous leader with a score of 86 points.

A little later, Mark Young even managed to top this and is now the sole leader again with a very strong 94 points!

Details for the new top scorers:
Crystal 9, 64Threads, 65536MB Hash
AMD 7970X
900 secs/position
94 Points = 59%
Submitted by Mark Young - Kingpin1

Crystal 8, 8Threads, 8000MB Hash
AMD RYZEN 9 3900X
300 secs/position
86 Points = 54%
Submitted by Daniel Reist

Congratulations to Mark and Daniel :)

Don't let those two naysayers drive you crazy. Do your thing and you'll be fine.

I wouldn't call myself a blitz champion, but I have won a few tournaments :)

Recently, I came to the conclusion that suffering fades faster when blitzing,
because the next game comes immediately.
That's why I've been a bit more active there recently.

Thanks, Jesus.
Yes, as for the examples I looked at in databases of mine out of those you give, I have some more info stored but I gave in .epd- collection above, in this one case I just took the shortest .epd- strings I have, to get the output shortest, having all the HTC114- ones marked as such anyhow, regards
