Hi,

first of all thank for the friendly discussion. I undestand your point of view
and I do respect it as I do with everybody points of view.
Still I do not agree with you...see below.

>The point is, even if the eval is -10, I am under no obligation to resign.

Correct.
I am asking to change the rule to force a program to resign when the score goes
down to -10 (a mean more or less a queen and 2 rooks down, to summarize).
Why I am asking to change this?
Because I think we better try to get closer to mid/strong players and they do
resign when the disadvantage is too high.
At the lowest national category, so I am not talking at master level, they do
resign if they are a piece down, not to talk about a rook down, so why not make
the programs get closer to that?
-10 is an intermediate level between what is today and what the average chess
players do to avoid annoying the people watching these games.
It is an idea and a proposal. I think this will improve the view chess players
have of computer chess programs.
Of course the programmers can say no, but before doing that think about why you
are writing a chess program. Do you do it only for fun or you would like more
people to get interested on this field and so increase possibly the custormers?

If this will be the new rule it will be the same for everybody.

Why we do not try to improve the idea we have on them and try to make them as
much as closer to human players we can and add options in that direction?
Some years ago I convinced Marty Hirsch to add a learning feature which was a my
idea refined by him. He was against at the beginning saying that it is only a
chess program after all, so why trying to increse the A.I.? The customers loved
that feature and that helped to increase the sells.

I know, but this is just a proposal for improvements. Only a proposal. People
are complaining that the computer chess market is getting lower and lower. Do
they lesson to the customers or not?
Now we are in 2003 and we cannot force the customers to get what we are
proposing. We need to ask them too. I mean what they would like and so on...
I hope I have been clear enough.
I leave the decision to you programmers, but do not tell that we (the users) do
not give you hints and ideas...

I understand you opinion and as I said I do respect it even if I do not agree. I
cannot go against a TD director decision in any case as this is not in my style.
This is something I never did and I will never do.

Some years ago, I was the operator to M-Chess in a tournament near where I live
and we were playing against a Yugoslavian chess player which got a better
position, but the program got a 3-fold repetition position. I call the TD and he
told me that I made the claim in the wrong way (I moved first and than call the
TD), so I could not ask for the draw. It was not important that I did not knew
the right procedure...
I accepted the TD decision without protesting at all. This is my style and I am
proud of it.
I hope the people understand.
I never criticized anybody. I did with SSDF when they did allow Fritz 5 to be
tested using a different version that the one sold (with autoplayer) as this was
against the agreements and recently as they were testing a mix of programs as
the agreement is to test sold units only.
I did not protest when other teams had more than one program or the book author
could play with more than one program as this was accepted by the TD.
These are only some examples to show you that I am not claiming this only becaue
it this case the TD decision favored us, but because this is my style.
