CT800 V1.43 released

[Scally]

Hi Ras,

Thanks for the new version, I’ve compiled it and updated it on my Picochess system.

I know you provide a RPi binary (thanks) but I like to compile it and use whichever version has the higher nps.

Oh, where is the file? What I can see is v1.42.

Uh? The download page has V1.43, but maybe there's a caching problem. Here's the direct V1.43 release page: https://www.ct800.net/sw_release_v143.htm

Now it's OK.

Congrats Ras, don't forget to submit your binary for next season's ZaTour

Already done so!

I know you provide a RPi binary (thanks) but I like to compile it and use whichever version has the higher nps.

Yes, compiling it yourself will tell the compiler to optimise for the specific CPU you're using, and that may sport a small performance boost.

Thanks for testing, that's about as expected. It would also move the CT800 from the bottom of the list, at least for a while.

Now it's OK.

Turned out I played myself with the caching - I configured internal caching at my hosting provider to 24h for HTML files to get maximum speed out of the shared hosting. Means, I should have disabled that particular caching temporarily 24h before uploading the new pages. But yeah, 24h after, the changes are through nevertheless.

[Gabor Szots]

A new release V1.43 of the CT800 engine is available, about 50 Elo stronger. It might even take a shot at the 2500 CCRL bar.

It has. I'm going to run some more matches to obtain a more accurate rating but I don't think it will sink much.

Thanks for testing, that's awesome.

Hi Ras,

thanks for the new version.
I like CT800 a lot and used your engine in combinaiton with Wasp on my Raspberry and DGT board for solo-playing!

Best
