Re: unit testing polyglot probe code....

I'm not trying to calculate the key, probably I'll check it too sooner or later. I was asking if someone known some famous and sound opening with en passant or promotion.

Probably the author of perfect2017.bin will be the best source of info

Re: UCI question

Probably something like that:

Save the command list in input.txt file and then:
Komodo <input.txt

Pay attention the it's not possible to analyze more than one position with a single file because uci require when performing analysis the input management is not blocked.

what are the game timing conditions?

but I haven't done a lot of testing with long time control, let's say 10 minutes/games or TCEC/CCCC time control

Re: Null move pruning, only when score >= beta?

probably when you have a static evaluation below beta and you give the opponent a free move, it's very difficult that you can have a beta cutoff, but also it will add very few node to verify that the result is below beta, so it make very small difference. you can see "null move pruning" as : if my s...
