Excellent progress! :)

Would have been way too strong in my Division 6 tourney. :shock:

That'd put Weiss somewhere around 2900 ELO if I remember correctly. That's a huge jump. Congratulations.

Incredible! I hope I'll be able to confirm that.

Looks like new Weiss is around 2900 indeed

Thanks all :D

I hope so too @Gabor

Still too soon to hang with the big boys haha :P @xr_a_y

Tuning eval params by itself probably gained +-150 elo :shock:

At some point, you'll get there, because the big boys are experiencing diminishing returns. Their progress is going to be slower and slower.

The one obstacle to reaching that level is time and resources. When you get to that level, every single code change has to be tested by 5000 games or so.

I'll have to look into that tuning stuff when I get there. I can imagine that settings for parameters that worked well when the engine was 2100 ELO, don't work well after it gained 30 more evaluation parameters, 5 new search enhancements, and is now over 2800 ELO.

Thanks to Andrew Grant and noobpwnftw, I have access to the necessary resources. :)

Maybe, some day, we'll both be on that platform. It'll take a while though :)

First, I'll have to upgrade my current computer for local testing at some point. The 6700K that was released almost 5 years ago is still fine for everything I do, except for testing chess engines after a code change. I'm still amazed how people got anything written that actually worked in the 70's and 80's...

With an access to OpenBench resources I think you will reach 3100+ quite easily, as the biggest challenge for "simple mortals" is the access to computer resources, it is indeed especially hard after 3050+ to get some elo quickly as every single change requires so much testing.
