Baracuda2016  (.abk , .bkt , .cgb , .ctg , .bix)

Well balanced book for testing engines.

Around 400 draw opening positions ( no advantage for any side more than 30 centipawns (+-0.30)) after move 8.
Positions were analysed by Stockfish , Komodo and SugaR.

All opening positions from previous book re-analysed , some  are excluded because of low winning percentage.

Don t need additional settings because there is no bad moves in this book,
but You can change the "Number of games" ("Variety of play") scale to
change the percentage of openings.

Just load into Your favorite GUI ( Arena , Shredder , ChessGUI , Fritz or Infinity ) and enjoy.

That is a very nice book.
I analyzed all the interior and leaf nodes and there are no serious gaffes in it.
That is very unusual for an opening book.

Including interior nodes, these are all of the positions with an evaluation of 40 centipawns or more:

Considering only the leaf nodes (book exit points) there are three positions with a centipawn evaluation of 40 or more:

Note that I do not think that these positions are as bad as I used to.  Having a few relatively polar positions contributes to spice in a contest (I formed this opinion from watching TCEC).

I actually think that positions with a score of zero after a deep search are worse than scores that are somewhat polar.
They lead to too many draws.

Thanks for keeping track of my work...

As I said before ; evaluation depends of few things...

All positions were analysed by Komodo and SF, and some positions by SugaR.

Hope You are aware that those engines dont evaluate positions the same...

All positions with -0.3 and higher were automatically excluded by Arena GUI ( every move from move 6 was analysed for 10 minutes or more ).

Regards from Croatia.
