This is C+ in less than a second by Jacobi.

Popeye is probably the worst tool for proofgames, unless there are a lot of captures. Jacobi, Natch or Euclide are much better.

Maybe the required code from Jacobi/Natch/Euclide could be grafted into Popeye?

Nice and promising!
From Julia’s presentation, Velmurugan is the first name, but it is stored as the name in Winchloé database.
Which is the correct use?

Thanks, Julia! I transmitted information to Christian.
And again congratulations to Velmurugan!
