Maybe the depth is still far too shallow to see an advantage for Black here That last search was only with 48 MB hash and on 50% of the CPU, so KG's system must be seeing about 6 cores / 1 cores x 4 GigaHertz / 2 GHz x 100% / 50% CPU time x enormous TT-advantage divided by 4 plies headstart but still quite a lot deeper...

Maybe the depth is still far too shallow to see an advantage for Black here That last search was only with 48 MB hash and on 50% of the CPU, so KG's system must be seeing about 6 cores / 1 cores x 4 GigaHertz / 2 GHz x 100% / 50% CPU time x enormous TT-advantage divided by 4 plies headstart but still quite a lot deeper...
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.
