Eval tuning I strictly do at fixed depth. I don't want external factors like time control or permanent brain to interfere. Enough volume will flatten all the horizon effects eventually, both sides.

IMHO the main drawbacks are: impossible to test depth sensible stuff like king safety and artificial same depth for midgame and endgame. But I agree for some evaluation parameters could be good, actually I will give it a try.

For self-play-ply-depth testing I am planning the following:

1. introduce a special parameter for internal testing;
2. when the flag is on increase the depth with 1 when queens are exchanged;
3. depth+2 entering the endgame
4. depth+5 entering the simple endgame

Or something like that.


Reading this, i ask myself why not making the depth sensitive to the
material phase values in general, when using fix-depth matches ?

Having an array useFixDepth[phaseValue] = depth ...
For late endgames the depth can easily be 2x or even 3x bigger than
for middlegame positions, and would be continious getting bigger.
(similar behaviour like in time-based games, or similar like
time/move then ?!)

eg: fullboard -> depth 8 or 9 and pawnEnding ending maybe 16.

just an idea...
