Thank you, Ruxy.

With pleasure !

But, first of all, a lot of thanks to Mr.Franck Zibi -the author- who kindly provided me this link !

If you want to use this engine under Fritz GUI, here is:


[ENGINE]
Name=ZChess 2.00
Author=Frank Zibi, France
Filename=Wb2Uci.exe

[OPTIONS]
Program=zchess.exe
MateScore=32000
OwnBook=true
TerminateHard=true


In ZCHESS.INI you can change:

-the hash;
-the path to Nalimov TBs;
-the existance of a log file(TRUE/FALSE);
-pondering (TRUE/FALSE).


OK, they are a lot of parameters, you can experiment, but this beautiful play needs the original settings !

I am not saying anyone wants to or does not want to- I haven't a clue. But if it were going to be tested ag. other engines, the following settings would be the best. Note ponder=true only so it won't revert back to its starting point after each move, which it seems to. Anyway, the gui will take care of ponder.

[Display]
noise=5
; The minimal depth before displaying the evaluation of

K_BEST_MODE=1
; When analyzing a game under EPD2DIAG, a value of K_BEST_MODE >=2
; shows not only the best move, its eval and its PV (Principal variation)
; but also :
; the second best move (with eval and PV),
; the third best move (with eval and PV),
; ....
; the (K_BEST_MODE)th best move (with eval and PV)
; For instance, With K_BEST_MODE == 2, the best move and the 2nd best move will be displayed
; NB: a K_BEST_MODE >= 2 will slow down the program...
; Default : 1

[Search]
min_sd=2
; minimal search depth, the program must (at least) reach this depth
; even if it is out of time : Be careful !!
; Default : 2

; Default : 35

selectivite=25
; Maximum number of plies to add to the search depth
; Default : 25

USE_COMBINATION_EXTENSIONS=TRUE
; Enable some tactical extension to find combinations faster
; This option is only used in analyze mode or under EPD2DIAG .

[TableBase]
USE_TB=FALSE
; Enable TableBase.
; They should be in the directory stored in TBPATH (see below)
; Default : TRUE

TBPATH=./TB;C:\CHESS\TB;d:\zchess\tb;
; The directory where are the TableBase.
; For instance: C:\CHESS\TB ; ./TB ; TB ; \\JUPITER\C\CHESS\TB ; etc...
; Only used if USE_TB is set to TRUE (see above)
; Default : ./TB


[MISC]
ENABLE_PONDERING=TRUE
; enable thinking on the opponent's time
; Default : TRUE

ENABLE_BOOK=FALSE
; Use the opening books (z_style.txt and z_book.bin)
; (another way to disable the opening books is with the command 'book off')
; Default : TRUE

ENABLE_LOG=FALSE
; We store all displayed info in a log file in the directory ./log
; Default : TRUE

ENABLE_LEARN_BIN=FALSE
; We store in the file 'z_learn.epd' the positions where zchess has blundered.
; Hopefully, zchess will not make exactly the same mistake again.
; Default : TRUE


[Evaluation]
DRAW_SCORE=0
; Contempt factor, in 1/100 of a pawn

OPPONENT_TYPE=2
; The type of the ZChess opponent

; 0 : the opponent type is unknwown
; 1 : the opponent is a human (try to open the position !)
; 2 : the opponent is a computer

ENABLE_RESIGN=TRUE
; Allow the program to resign in a hopeless position
; NB: ZChess will not resign if its opponent is out of time
; Default : TRUE


ENABLE_DRAW_OFFER_WHEN_GAFFE=FALSE

Note I have book=false and TB=false, but that's just me. And as for the best draw setting, ask someone like Graham. Notice I didn't touch the settings I don't understand.



Thought this might help.

Hi !

Its strength is a bit over Ikarus v0.18 (2280 ELO CEGT/2400 ELO CCRL on 4'/40), so a master level .

But the important think is its phenomenal play. A lot of ideas for a human player !

Take a look to the below game: an incredible attack until the last move, over all the table. I never seen before this style to annother ches engine: commercial/free/private !

I can tell you this. I just assumed it was an engine for humans to have a good time with- but I set it up and it is kicking the shit out of some 2200 and 2300 engines.

[Jim Ablett]

Here is a Uci version of Zchess 2.00. Actually this is a 'proof of concept' test version just to see if it could be done. The executable was created with an application called 'BoxedAppPacker' which bundled all necessary files in to one executable and runs them from it in a virtual space. So this executable contains the Winboard Zchess.exe +Wb2uci (using George's settings).
This type of executable is notorious for triggering Antiviruses, so if you get a warning (I didn't) just add it as an exception. Let me know how it works for you.

I tested it working in Arena & Fritz 13 (32 bit).

http://cl.ly/Kz9t/zchessUci-2.0.0.zip

This app doesn't work with all engines though. it's rather hit and miss. Crafty didn't work unfortunately.

Look, Jim- I have been up all night and I am just heading to get some sleep. I just saw your thread, but it is the last thing I can stay awake long enough to read. Tonight when I wake up (it is 11:20am Sun.,as we speak)- I will immediately take a look at it- don't let it go anywhere. This has my interest now!

BTW, Jim_ I assumed at first and did go ahead and enter in the ini file that player=2, which means he knows he is playing a computer. Naturally setting it for a human and then running an engine ag. it would not be good. But what about leaving it unknown- then we might get the best of both his types of play. Thought I would run that by you. Back tonight. Please leave the link.


Thanks,
