Crafty 25.6

[MikeB]

Bob has made a recent minor update to fix resignations and draw offers

Linux and macOS exes are available under the /src folder

https://github.com/MichaelB7/Crafty

Would be happy to include Windows exes if someone can provide them

Hello MikeB

this is offtopic sry but you said that you wanted to release a new Honey++ after SF11 came out (if i remember correctly)...is this still your goal and by beeing offtopic already: is it possible for you to share the "Crystal-Fortress-Detection-code" by Joseph Ellis somehow or link me to somewhere i can find it, id like to play with implementing this in some compiles i plan here and there ?

greetings, Peer

Is this a typo? Is it official 25.4? Are there any functional changes from previous version?

[bob]

There was a 25.4 with SMP fixes. The last two had some various bugs fixed dealing with draw offers and such. 25.6 is now the latest official release...

Is there a windows binary?

Hardware issues with the new machines - it was already to go - and now since SF dev team has done so many patches since SF 11 - not sure. Will have to see the impact on Honey - may or not be significant. Anyway - looking forward to getting the machine back. Planning on making it a dual boot with Windows so I can build macOS , Linux and windows exes and not be a burden to others. Scally will continue to do the Pi exe’s since he a pretty nice setup and it’s not a burden for him.

What are these 2 epd files for in the opening directory ?
Crafty opening books are generated from a pgn file.

For the record, 25.5 had a couple of important SMP fixes. I won't go into them here, anyone can download the source and look at main.c. It was a performance improvement, not a crash fixer. All were "Elo enhancing" fixes but not major.

25.6 I caught offering a draw in a won SYZYGY ending. Problem was, in Iterate() I can find a book move, an EGTB move, or a search result. Since the move wasn't a book move, and wasn't a search move, it was obviously an EGTB move. But Crafty used to use Nalimov tables and terminated the search after just a few plies rather than with special code. This "hole" would cause main() to conclude that since it wasn't a book move, it must be a search move. But the score was 0 since all I use in this case is won or lost (yes it uses the W/D/L tables during the search, but once in an EGTB position it doesn't return all the PV info. So you could see a draw offer every 5 moves in a won (or drawn or lost) EGTB position. Just did not cover this case when I did the SYZYGY conversion, but it is now correct.
