What do you mean about stalemates? I have only looked at checkmate positions from the puzzle database, so these are not in the data

Thanks! Yes, the corner is a 2x2 if you remove the out of board area. I think some patterns are mirror images of each other, but not completely sure yet, so have to investigate it

Ah yes, makes sense to avoid a pawn and a bishop to equal a knight etc.! Will make this improvement, thanks πŸ™πŸ»

It now runs using this db instead of stockfish, which is quite an improvement

Will try to implement this, thanks!

Looks interesting! Then I could save a lot of engine time

And how would you define repertoire coverage?

1 year ago 0 0 1 0

Sure! I have used python and created the code using Replit.com

I used the lichess api to connect to the opening database and retrieve stats. It takes about 2-3 hours to generate 20 lines due to analysing 1 position leads to retrieval of data and getting evals on all the moves played more than 5%
