Test Sets with Arena...

For test sets it's a good idea to use the Interface Arena 3.5.1. Arena creates an interesting output (txt-file: "report") of all solved tasks. Unfortunately Arena don't generate a r anking list of all engines. Perhaps here is a programmer who can make a small tool for that? Thanks and greetings: Wal...

Re: Nightmare II (Test-Set)

Hi Walter! Great collection of yours once again! Did you realize the discussion about the position you gave as 07? No - thx. Yeah, Qf5 is the only move (Festung), all others are losing.

Re: Nightmare II (Test-Set)

Thanks for your friendly motivation :-)
And of course Dann is right, your collections of positions are always high quality and very challenging (as I would expect from someonelike you who is a connoisseur of fine music and chess). Thanks for your work.

Re: Nightmare II (Test-Set)

Thx for your impressive test (and congratulations on your magnificent hardware... ;-) Perhaps you can repeat your experiment, but this time with Komodo or Houdini? I'm sure, this will probably give a different move ranking.... But maybe you're right, there may be two correct solutions. I will check ...
