Re: interesting test move

Post by Eelco de Groot »

Some builds took a lot longer but Ancalagon build 110 found Nd5 in 40 seconds.

I made an EPD of the position for the 'Arasan Expanded' testset-clone, it's for private use, I don't yet have a good set of positions from testgames so it's >90 % Arasan positions...:

It was good to see that Rybka does not yet reign everywhere :) :

Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.
