2. CTF should be closed

This is so much cleaner than what I had been trying to do - Thank you! Following up on this, I ended up adding code to Abbess to pull the selection of pgn files I wanted - pgn games truncated to where a certain number of pieces are left. However, I actually only want games that are still in progress...

Following up on this, I ended up adding code to Abbess to pull the selection of pgn files I wanted - pgn games truncated to where a certain number of pieces are left. However, I actually only want games that are still in progress, i.e. no games ending in checkmate or draw. pgn-extract has --checkmat...

I'm trying to filter pgn files for certain endings, except I want the PGN to be truncated once that ending is reached (e.g. KQRKB). pgn-extract -z mat_kqrkb.txt -D -o kqrkb.pgn 1.pgn 2.pgn 3.pgn will find the KQRKB games, but it gives the full pgn of the game, rather than stopping once KQRKB is reac...

Elo figures are already correctly reported with +/- Elo error bounds. There is no need to ask the Stockfish developers to truncate anything. However, if they are using LOS in fishtest, they should be warned that they are tuning Stockfish with a uniform PRNG (given enough games) It's only a uniform ...

Is there a program out there that will take a FEN position and attempt to generate a legal game that reaches that position?

What about
3. By playing an extra 100 pointless moves, it will occasionally wander into positions where an AB searcher can find a drawing continuation, turning a won game into a draw.

Thanks for the explanation. I don't think I ever had eval as one of the criteria, and that appears to add 30 elo in my initial tests.

So, I've always struggled to get a null move search that gives me positive results. I decided to look at the rules that Stockfish uses and see the following: // Step 9. Null move search with verification search (~40 Elo) 1 if ( !PvNode 2 && (ss-1)->currentMove != MOVE_NULL 3 && (ss-1)->statScore < 2...

The only way they have of communication requires giving them my email and I don't even know if they'd sell it or whatever. It isn't rocket science to share the source (they chose to NOT include it with the compiles and to NOT update their github), so it's clear they preferred to have a closed Stock...
