Playouts play a HUGE role in strenght. All the games I've been running use the default 800, which makes it rather weak but is good for the training purposes, as it provides more games/time. I see you use 50000, that's a nice number and should make it much stronger.

I upped the playouts to 150000 (equals 30-40s/move on my machine) and had a quick match against TSCP 1.81b which was using 1 min/game. The network in use was 1aa02cb1. The game with Leela using the white pieces did not look too bad for :

The reverse game however, was very hard to watch with Leela blundering a knight on move 2.

Maybe I was bit too optimistic, but let's see where this will go. Interesting days ahead for us.

Yep, but training games are not meant to be good yet, they are just meant to be fast. That's why they are played with a crippled Leela.

Hi Gary, when I visit that page it is not clear how I can contribute GPU time to the project. the page is missing a 'call to action' button. add a green button which says 'Get involved' which links to the client software and includes instructions.

In the current .7z file LCZero/Setup_Training.bat includes a typo:
echo Tun.bat will be started once you press Enter
should be
echo Train.bat will be started once you press Enter

I have one of those. I also have an older Quadro 5000 but it's not as powerful.
