Witz_a17 sends a wrong resign command and probably
has a problem with stalemate recognition!

(it should send only 'resign' not 'resign xxx' in the same line)

Matilde_255 played on after a stalemate!

Cheops even lost on time once at depth 4 setting in 40/5, hopefully
gone at 40/15?

MSCP_16gJA lost on time once in a drawn K vs. K+P ending(no debug)

Skaki_122JA lost on time once in move 39(no debug)

In a game AtlanChess_20 vs. Popochin_20c Atlan claimed an illegal

SharpChess2_23 seems to reset the setting of book usage sometimes?
Is there a way to save the setting finally (no config/ini file)?

--------------------------------

From all WB programs which are allowed to use a ThinkerBook in
the Qualification according to my new rules(WB engines not older
than 6 months at start date), only 2 work:

Raffaela_014 and JSBam_050

not working:

Witz_a17, RomiChess_Proto2i, JaksaH_012,

Witz_a17 sends a wrong resign command and probably
has a problem with stalemate recognition!

It is one of the many problems the unstable alpha version has. I'm in the process of completely rewriting the engine, so hopefully I can qulaify for your next season of RWBC with the newly written engine.

What about just fixing the resign command in the old Witz?
At least it would play then in current RWBC, if it's too early for
the new program.

Youk comes with a 3MB book.dat, nevertheless it seems not
to use the book file and instead creates an empty file book.txt
in the same folder.
If I rename book.dat to book.txt before the game it creates
an empty file book.dat (:

Hi Gunther,

TRex_19b sends no promotion piece!

I have a workaround for this in a development version of PolyGlot (Leo mentionned another engine in this case too). I think it's even available in the PolyGlot 1.4 beta (with Chess960). I've not tested it however. Are you interested?

Fabien.

Yes of course BTW good luck for your commercial future
with Fruit! You deserve some from it.

Best,
Guenther

[Fabien Letouzey]

Yes of course :)

OK, I'll have a look tonight and give you the option tomorrow morning.

If you need it today, ask someone who's code the source code (e.g. Leo or Tord). There must be an option about "promote/promotion-xxx" in option.cpp. In fact you can probably see it inside of the binary (recall it's the 1.4 beta only, not an older version).

I mentioned before that it is not the only problem in the old Witz. For example : In the game you have posted there, Witz should have won a long time ago but it spends time avoiding making mate (most probably a stalemate bug where Witz thinks mate=stalemate). The move generator in the engine is not tested in the old version. In my new engine I have imiplemented perft so bugfixing the old engine will be more difficult than just continuing my new engine (with better datastructures and the ability to go SMP).

Hi Gunther,

OK, I'll have a look tonight and give you the option tomorrow morning.

The option is "PromoteWorkAround" (in the [PolyGlot] section). Check that your PolyGlot binary contains this string first. If it doesn't, please contact Leo.

Hi Guenther

I noticed this already. But if you give Youk the book.txt from TSCP, it will use it !

There is no mention of using TSCP code in the Youk package

Olivier

[Guenther Simon]

Skaki doesn't use its book here, even with exactly renamed
ini file. Of course the tournament book is in the folder and
specified in the ini file.

There is now a release 2.4 of Sharpchess that includes new bug fixes.

I believe that the bug that was causing a timeout issue was due to the backup file that is saved every time SharpChess makes a move. It looks like the backup file was being incorrectly named, which should be fixed now.

The opening book, built into SharpChess, is not a tournament level book, and is consequently switched off when SharpChess is run is in WinBoard mode.

Thanks Peter! The problem seems to be fixed. It also seems
SharpChess2 is able to use my small default Thinkerbook
without problems. (After your description above it is allowed
to use one now, according to my new rules)

In the game below Surprise_425 givs away its Q for nothing?

Hi, Guenther,

thanks for your bug report, I will try to fix it asap (hopefully tonight or tomorrow in the evening). I thought I had already found and fixed the mate score hash table problems in 4.2.4 but obviously there is some more work to do.

In this game, Surprise seems to retrieve a "mate in 3 plies" score from hash table for the position after Qc2+?? Bxc2, then transforms it correctly into +9995 (mate in 5 plies from root), and in iteration 4 it terminates the search because there can't be any better move than one "mating in 5 plies" (mate in 3 plies would have been found by the previous iteration).

Everything quite "logical", except for the wrong mate score . The simple move "Qxg6" would have left Surprise with an advantage of two pieces and probably mate in few plies (I did not use an engine to analyze the position, nothing installed here at work).

Hi Guenther,

unfortunately I was not able to exactly reproduce the problem with Surprise-4.2.5 or 4.2.4 (I did not try older versions). On my PC, Surprise does not play Qc2+?? but hxg6. FEN: 2r4k/p5pp/1p4B1/7n/4q2b/4P2P/PP1K2P1/1R3Q2 b - - 0 1

Going one move back, instead of Rxd2+(?!) it mates in 5 beginning with Qc4+.

Can you give me some more details: hardware, GUI, settings (hash size), perhaps the debug log if existing?

I'm afraid I will not provide a fix before RWBC qualification starts. I hope the bug does not disturb the tournament, it's only that the chances of Surprise to qualify are slightly reduced.

IMO hashtable bugs are rarely to reproduce. (Have you tried to feed
the whole game history instead of a FEN?)
Hash was 128MB. My hardware etc. can be found on my hompepage BTW
-> 'Conditions & Specs', but anyway here it is again:
P4 2.66 Ghz 512MB WINXP SP1.
The debug is of course saved because I quoted from it above.
I will send it to you.

Guenther
