No doubt that Junior is very good, of course.

It depends on what kind of change I want to test.
Self-test is a very good test when I change my search algorithm. It is more
questionnable when I try to introduce a strategic improvement.

You are right. This test is sometimes not very relevant.

NEVER. 10 games is NOT ENOUGH.
I have found that a 30 games match has a +/- 5% error margin. That is a 50%
result can mean 45% to 55%.
So a 10 games match gives NO USEFUL INFORMATION (unless you are playing Chess
Challenger 3 against Rebel 10).
Of course if it is 10 games against A, 10 against B and 10 against C, it is a 30
games match against an average opposition and it is useful. I suppose it is what
you meant?

Yes, it is fun. We should not take tournament results too seriously (except when
I win. :) ).

Yes, I know... The problem is that I'm leaving to France on Thursday. I'll spend
1.5 month there. Where I will be, I'll have only 1 computer, so I fear that
you'll have to wait until October to get an auto232 version...
