Andscacs - New version 0.91

[Henk]

Maybe Kai Laskos has statistics about average growth of an engine. Or estimates about long term maximal growth.

[Fabio Gobbato]

How do you use this big amount of data?

How do you use this big amount of data?

The files are the pgns of the games played with cutechess-cli. Each computer that runs a test, generates one pgn. Then I fuse the different files in one and I use Ordo to check if the results are ok to accept the version. So there are more than 500 pgn files in those 8 GB.

I also used Arena the first months of Andscacs

You are the man!!

Never is easy but never stop!
Mai és fàcil però mai s'ha de parar!

Detailed changes other than already commented:

* order of quiets: bonus for castling; removed penalization for piece going back.
* Improved the detection of candidate passers.
* King safety: Less attack if queen can be taken immediately; bonus for attack of the queen diagonally to squares near rival king; less attack if no minors attack and the rival defends with minors.
* Improved endgames: krkp, krpkr, krpkb
* Improved outposts.
* Improved imbalances: queen + minor vs two rooks; Queen vs rbn; Rook vs knight.
* Improved move ordering of root moves: some memory of previous iterations order.
* Stockfish changes that worked:
