Re: On-line engine blitz tourney April

Thanks for running this.

Aside from logging on, I missed pretty much everything due to going to get a chinese takeaway meal for the family, consuming the food, then watching a classic film with one of my lads (Pulp Fiction).

Re: King safety evaluation

Well tuned king safety is not easy, not something that can be cracked quickly, for sure.

I don't have the answer, other than gradual tweaking then lots of testing. Maybe automated tuning (Texel tuning etc.) is a good way forward for tuning king safety and other stuff.

Re: Cutechess-cli and SPRT

You should be aware that SPRT is only efficient if the Elo difference is comparable to the bounds. If this is not the case then SPRT is very inefficient (compared to a standard fixed length test). Interesting.. why would that be? So the parameters I'm using would be more efficient if there is only ...
