Over 25,000 opening positions, 10 moves deep, each one evaluated with Stockfish 8 to have an eval between -1/3 pawn and +1/3 pawn at depth 10:

Subset of the positions, filtered to be within 1/3 pawn of even at a search depth of 20 (20,376 total positions):

Do you have a log of the analysis or Epd records that contain the analysis?

I do not have the analysis, sorry. 20 ply is not actually that deep for Stockfish. It is just a sanity check here to look for even positions.

Hi Jon,

why 10 moves for all? With 10 moves for all you produced to lines like B01 a lot of material and to lines ECO Code ended with move 10 nothing. So the database can't be balanced inside the ECO codes. Furthermore, engine can better search for newer theory from balanced positions three moves after ECO code was formed. With such books we can create very high material for opening experts.

Much ECO codes formed after 1 one others after 14 moves. To important ECO codes material lost. To much others material is to long ... to many lines after ECO codes was formed.

I am using min. 5-6 moves (for codes like B01) and for all others three moves after ECO Code was formed (max ECO Code = 14 moves + 3 = 17 moves, with the results that I have to each ECO code some balanced material. Very important for book Building or to 20-30 ECO codes nothing find and book is playing to often B01 without priorities ... for one example.
