Hi Vincent,

Nice to hear from you again.

Hi Ed,

In itself running fixed depth matches is not a bad idea. However it tunes a lot better if you get through tactical barrier. That barrier is far above 8 ply.

Of course you are right and in an ideal world I would use 16 plies. But 8 ply plus 10,000+ games is good enough nevertheless since the volume weeds out the randomness.


8 ply is too little. The randomness of the shallow search not getting through tactical barrier means you suddenly need 100k games instead of 10k with a bit deeper search depth, as randomness always converges towards equality (50% score). So randomness you can never filter out very well as it has the tendency to converge towards that 50% score. Avoiding randomness in the first place should be your main focus.

Even then it will never tune accurately of course, they use better ways of tuning than this nonsense testing. For this if i may refer to that Stockfish team first says they test 1000 games at 1 0 level, now statement is they test at 5 seconds a game + 0.1 , whereas they're higher rated than crafty and crafty already had to move up in time control, meanwhile crafty plays 40k games, not 1000. Then even despite being retired i assume you smell the contradiction of the random statements the dudes do here.
