[Vladimir Medvedev]

Geschrieben von: / Posted by: Vladimir Medvedev at 15 March 2004 11:48:50:

New features:
* Hash structure optimized: sizeof(CHashEntry) reduced from 32 to 16 bytes,
sizeof(CPawnHashEntry) reduced as well.
* New console command: book digest
Creates plain text list of all opening lines in pgn file, useful for creation
GreKo's repertoire file.
Enjoy.

Hi Vladimir!
I am testing GreKO 2.71 under Fritz 8 GUI as Wb Engine.
Here my *.INIT file:
[Parameter]
CommandLine =
Author = Vladimir Medvedev
Engine = GreKo 2.71
Debug = False
[Support]
AnalyzeMode = true
PonderMode = False
CastleAndEP = False
Settings are default.
I load my first position of my Testset (from CBF database), and here are the first
Analysis on P3 600 MHZ hardware:
EDTest position 1

2qr3r/1p1n1ppk/p3p2p/5b2/2PP2NQ/6R1/P1B2PPP/R5K1 w - - 0 1
(Best move is Ra-e1, next best move is Nxh6)
EDTest01
2qr3r/1p1n1ppk/p3p2p/5b2/2PP2NQ/6R1/P1B2PPP/R5K1 w - - 0 1
Analysis by GreKo 2.71:
1.d5
² (0.39) Tiefe: 7 00:00:00 473kN
1.d5
= (0.23) Tiefe: 7 00:00:00 1kN
1.d5 exd5
= (0.16) Tiefe: 7 00:00:02 62kN
1.Ld3
= (0.14) Tiefe: 8 00:00:17 953kN
1.Sf6+
² (0.33) Tiefe: 9 00:00:54 2985kN
1.d5 exd5 2.Ld3
= (0.10) Tiefe: 10 00:02:35 9447kN
(Nemeth, Privat 15.03.2004)
Now I load the next position 2, but I cannot seen the “Thinking line”.
Why this?
EDTest position 2

6k1/1b3p2/1p2p1P1/pPp1P3/2P2Q1P/5PKB/8/3q4 b - - 0 1
Here I see that GreKo does analyses but I cannot see the HV.
Now I load the next position number 4 (black to move):
EDTest04
r2qr1k1/pp1P1p2/b4bp1/6Bp/4p2P/1P3P1N/P2Q2P1/3RK2R b K - 0 1
Analysis by GreKo 2.71:
1...e3
= (0.09) Tiefe: 4 00:00:00
1...e3
= (0.20) Tiefe: 5 00:00:00 12kN
1...e3
= (0.05) Tiefe: 6 00:00:01 44kN
1...e3
= (0.01) Tiefe: 8 00:00:14 859kN
1...Le7
= (0.10) Tiefe: 9 00:00:44 2898kN
(Nemeth, Privat 15.03.2004)
Now I see again the Thinking Line!
What was wrong with the position 2, no Thinking Line to seen
(see Diagram)?
Thanks,
Eduard
PS (german): auch deutschsprachige Antworten erwünscht.
Mein Problem ist, dass ich die HV in position 2 nicht sehen kann.
Mal kann ich die Analyse im Analysefenster sehen, mal nicht.
Wo liegt das Problem?

Hello,
I have tested GreKo on these positions in console mode, and analysis is OK.
I did not test yet under Fritz8 GUI, but I'll do it and try to fix the problem.
But it's rather hard without logging of comands GreKo receives (I had it in GreKo 1.10 but have not implemented yet in GreKo 2.x).
I'm 90% sure that tre reason is WB protocol implementation details in Fritz8.
Did you use WB2UCI adaptor or something else?
Regards,
Vladimir

Hello Vladimir!
I understand.
Thank You very much.
I am no a expert with Wb2UCI adapter, I am sorry.
I let runs under Fritz 8 only UCI=UCI and Wb as Winboard.
Only The King I let runs wird Wb2UCI adapter, but the config-file is not from me (I must learn it).

Best,
Eduard

I am just surprised! Does Fritz8 directly supports Winboard protocol engines? I never trued to find this feature in F8, always using WB2UCI.
WB2UIC-config for GreKo is trivial:
[ENGINE]
Name=GreKo
Author=VRM
Filename=Wb2Uci.exe
[OPTIONS]
Program=GreKo.exe
; See Wb2Uci.html for more options
