Hi,

After two years, I have a new version of Lime.

It's still weak - after a couple of rewrites and lots of testing, I've ended up back at square one and continuing with the structure used in v62.

It should be about 50 points stronger than v62.

So at least I'm improving at the same rate as Shredder .

One point to mention, I owe a "Thank you" to Richard Pijl, who wrote to me and was kind enough to point out the hash scoring bug that was causing Lime to throw away pieces.

Changes from last version:

Move ordering redone
Pondering (I hope - it works on my machine)
Hash Bug fixed

Playing style:

It still loves to allow the opponent to create connected passed pawns.
It is overly optimistic about it's position.

Todo:

Proper SEE
Checks in Qsearch
New Eval

Thanks to everyone who is interested, tests, responds to questions, and keeps this community going.

Thanks Richard!
That was a long time. It made me even reupdate my anthology pages
right now after I already had uploaded the new files

Best wishes,
Guenther

Thanks Richard.

I second that....

Thanks for the nice replies from you all

Richard

Does your program use tablebases?

Yes, it does.

Can be set by the .ini file (needed for WB mode) or by the GUI in UCI mode.

Richard

I looked at the code, did not see the EGTB.CPP that is part of the tablebase distribution.

Sorry, I though you meant hash tables.

It doesn't use endgame tables.
