Re: Meaningful ageing of a hash table

I recommend people to purposely restrict themselves to less RAM and less cores and try to find the best moves that they can, faster hardware has made people lazy and rely on poor methods that hide their defects because the engine just reaches high depth and it masks what could be improved.

And of course the...
