Enjoy!
Álvaro.
Note that the win rate is slightly larger here than in the Edwards study (both at least a billion games, so the difference is significant): 15.46% vs 15.3%. This is because it uses 6-fold-rep and 75-move rules for declaring draw. Some of the games that would have been draw after 3-fold-rep or 50-move will still result in a checkmate in the mean time.AlvaroBegue wrote: ↑Wed Jul 24, 2019 1:32 pm After searching the web for about 3 minutes: http://wismuth.com/chess/random-games.html
