Re: Find: Nd5!!
On my rather old AMD XP1800+ (1.533Ghz) it takes Ruffian 2.1 with 128Mb of hash a bit more than a minute to come up with Nd5.

What does the designation mSD7 stand for (I guess it is a custom build or specific UCI settings, but I am curious)

Re: Find: Nd5!!
The uci option "Minimum Split Depth" is set to 7, instead of its default value of 4. Testing indicates this yields stronger play when using 8 threads.Dann Corbit wrote:What does the designation mSD7 stand for (I guess it is a custom build or specific UCI settings, but I am curious)
