1337chess PRO Anniversary!!

Today is exactly a year since I've began working continuously daily on 1337chess PLUS or PRO opening book series. Engine chess and making opening books has been a hobby of mine since 2005 and this is the most tedious and the longest that has been developed so far.

Years of CPU time has been spent, over a thousand book versions and a couple of terabytes worth of opening books tested. Thanks for all your support, we hope to continue making better opening books in the future. :-)

A highly experimental book mine which you can use in any GUI besides using Aquarium Adapter. Included is a specialized Polyglot UCI adapter, which is very easy to use, simply copy your engine of choice in the polyglot directory and put the folder directory and the engine name on the polyglot.ini and install the polyglot.exe on any GUI you want like a normal engine. It should play instantly on opening.

I recommend disabling any GUI books to purely use the polyglot book, that is if you use fritz you can create a blank ctg or make sure it loaded no book. Absolutely no other settings required.

Regarding book strength, I don't guarantee it but it should be decent enough. If you want a heavily tuned book and guaranteed strength, try the latest version of 1337chess PLUS it is the current top leading book. Although currently in ctg you can also use it on any GUI using Aquarium Adapter.
