Is there a fen suite to ...
... check the accuracy of a material only search at depth 1 to n when engine has no extensions (except for qsearch that is captures only) or reductions?

I don't think such a thing would make sense except for a minimax version which would not be useful.
Even alpha-beta would be hard to make repeatable unless the move ordering was somehow idealized.
And if you have pruning like null move, then the results lose their meaning.
Out of curiosity, what is it that you want to measure with such a test suite?

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

I have a new engine, Bricabrac, that is currently a material only searcher. It does not have null move, yet. All I want to verify is at depth n does it find material truth for depth n.

Is this pure wood count, or do you take material imbalance into consideration also?

pawns.epdce values are side pov. First position black is ahead by 1 pawn. In the second, white is ahead by 2 pawns.Code: Select all
