Subject: Problems with Fritz UCI
|
I'm writing a UCI chess engine, mostly as an interesting way to learn
data structures and algorithms. I wanted to use Fritz11 as the front
end, but I couldn't get it to work --- it would load my engine, but it
wouldn't move the pieces when I sent it my moves. After hours of
poring over the protocols trying to find my mistake, I downloaded
Arena and installed my engine into it. It worked perfectly.
Does anyone know if Fritz has some quirks that make it expect
something not in the protocol? Am I using an outdated protocol (I got
it from http://www.shredderchess.com/download.html )?
I did get Fritz to work with Glaurung, another UCI engine, but in
looking at its source and also capturing its exchanges I don't see it
doing anything essentially different than what I'm doing, except that
it has about a thousand options that I don't have. The protocol says
that you just need to send a "bestmove" line in response to a "stop"
line, and I don't see how even I can screw that up, and as I said
Arena is happy with my engine.
Any tips greatly appreciated.

Roman, thanks for the tip. I had my options after the uciok, and when
I moved them before it as you suggested, Fritz started responding.
Thanks again.

Apologies for the late reply, I was out of town for the long July 4
weekend. Also apologies if this is a duplicate, but I don't see the
response I wrote an hour ago.
Thanks to everyone who responded. I haven't solved the Fritz problem
yet (I had already tried info commands), but since Arena works so well
for me, I will keep using that for UCI, and just use Fritz for
analysis. I also found that Arena contains an invaluable tool for UCI
authors, namely a debug window that shows all exchanges between the
GUI and the engine. My compliments to the author.

Thanks to everyone who replied. I was out of town for the July 4
weekend (big holiday in the US) so I apologize for the delay.
I tried using an option as Roman suggested, but it didn't help. But
frankly I don't care about Fritz anymore; since Arena works so well I
will use it from now on for my UCI games, and Fritz for analysis.
For anyone else trying to write a UCI engine, one thing Arena has that
is absolutely invaluable is a debug window that shows all the commands
exchanged between the GUI and the engine. My compliments to the
author.

Hello,
Noah's arch was built by an amateur. The Titanic was built by professionals.
The same is true for Arena vs. ChessBase. You know the result, don't you ?
And no I will not do the job which should done by ChessBase support.

P.S. A new version of Arena will be released soon, sorry still beta guys
but still free. Also the forum will reopen and we will might have a Wiki
too... So leave the Base and ... join the Arena.

Er, that Arena's just a legend and ChessBase is at the bottom of the
Atlantic?

I prefer Arena in a comp vs comp match. Just a question for you. I
want to play a 'gauntlet' match using a specific opening. I would
like the 'main' engine to be black. is this possible? I can get it to
work as white (in which I have several openings that I want games for)
but seem stuck when trying to get it to work with my black openings.
Thanks

Hello,
As it looks like I am afraid you will have to neglect the games plays with
white and only take into account those played with black (switch sides). I
will take a closer look. If it is not possible we will see what we can do to
make it possible.

Hi,
you need to provide at least one option to Fritz. Don't ask me why ...
Just provide a dummy option to Fritz and it should work. I assume you
don't buffer i/o.
Something like that should work:
....
printf("\nid author John Doe");
printf("\noption name useInternalOpeningBook type check default false");
printf("\nuciok\n");

Most UCI engines work fine in Fritz, so I don't think it's something
hidden within the Chessbase GUI. You are using the latest UCI specs.
One possibility may be that the two GUIs are sending commands in a
slightly different order, and something isn't getting initialized when
your engine runs through Fritz as opposed to running through Arena.
