Hi Nick,
well, there's an important difference between entering a move sequence or entering the resulting position, and this difference is castling rights!

Among all the hundreds engines in MessChess I only remember 1 or 2 which allow entering castling rights when entering a position, and so this option is not implemented in any plugin (for WinBoard or Arena).
IOW, from your FEN string (in WinBoard) only the following part is used in the plugin (and entered in the engine):
r1bq1b1r/ppp2kpp/2n5/3np3/2B5/8/PPPP1PPP/RNBQK2R w

So it's just the engine's decision, whether it accepts (or makes itself) any castling moves depending on the positions of the king and rooks.

Regards,
Franz

Hi Franz

Thanks, so you think the problem is castling rights, which also adds the extra search time? (13 seconds to 31 seconds). Unfortunately, with FEN's there are loads of positions where castling remains an option. So, I guess I skip FEN's and just do the manual entry if I am testing games.
No complaints Mess ROMs work, it just would have been a time saver with my tests.

Are speed ups reliable will I get the same moves at 300% as I would at 100% or is that also inconclusive? I am looking for ways to shorten time without compromise.

Regards
Nick

Yes, I'm quite sure that castling rights are the reason for this difference.
But it depends on the engine: some engines may always allow castling (after a position setup) when the king and the rook(s) are still in their original positions, others may not.
As long as your computer is powerful enough to run the emulation with the speed value (x%), you will indeed get the same moves.
You can check this with 'Options > Show FPS' (or key F11) in the engine window: if the value in the upper right corner is about the same as your speed value (x%), then the emulation is correctly running with this speed.

Hi Franz,

Thanks, I will try it. Also, I will try a couple of other positions that don't involve castling to have peace of mind of when to use Winboard.

Hi Franz,

Ok in this position MessChess and MessChess Winboard with Mephisto II 3.579 Mhz at Level A3. 8 Seconds = 3. ... Nf6



I think this confirms that the problem is centered around FEN's that still require the castling option.

Best regards

Hi,

nach langer Pause gibt's wieder mal eine neue Emulation, den Krypton Regency - vielen Dank an 'hap' und Berger!

Wegen der H8-CPU ist er direkt wieder in MessNew implementiert, aufrufen läßt er sich aber aus allen CB-Emu-Programmen.
Das Plugin hat mich einige Nerven gekostet, weil er (obwohl ähnlich zu den Excaliburs) doch einige 'Eigenarten' (um nicht zu sagen 'Macken' ) besitzt - soweit ich es getestet habe scheint aber jetzt alles zu funktionieren.
Bei direktem Spiel gegen die Engine ist eine Besonderheit zu beachten: für eine neue Partie muß man die Taste [NEW GAME] länger (ca. 2-3 sec) gedrückt halten bis "HELLO" in der Anzeige erscheint, und sie dann sofort loslassen, sonst startet die Engine nochmals neu - ein Soft- oder HardReset ist da die einfachere Lösung.

Grüße,
Franz

Hi Franz,

I think I found another FEN problem which might need a correction in GK2000:



This should be a Black to move FEN. GK2000 starts with a White move. I tried it on another Black to move FEN and the same thing happened where GK2000 wants to play a White move instead.

Regards
Nick

Hi Nick,
yes, a stupid mistake at the end of the setup routine in the plugin.
And the same mistake also existed in the plugin for the Saitek ChessAcademy.
I've now fixed it and also made a small change in the Excalibur plugins (for Igor & Ivan).

Thanks for reporting this bug,
Franz
