OK, I accept that.

This is only a question of how to program this 3min/move. If you think your
program does worse with X2 then you can and should change it into X1.

Right, I forgot that Shr2 couldn't do this.

That was not my point. I put it out again above.

Then read above the 3 lines.
And, referring to your feture list, except for the 5-man EG handling there is no
unique feature.
And I ask myself if it is necessary to mention self-evident features like epd
and cbf support. As I said I am spoilt. :-)

No. Now I found out what it is:
If I load a game out of a database it works. If I replace the game then
afterwards F8/F7 don't work any longer.

Hey, I was the only one believing that Shredder had better position after the
quality sac. I guess it was the only chance for counterplay, otherwise Shredder
would have been smashed easier.
And you didn't look full of sorrow but more than a sportsman.
However next time I'll come to you and say who I am. :-)
Uli certainly also doesn't know who I am although he looked forward meeting me
in Paderborn. Usually I don't go around telling everybody who I am because I am
no important guy to do so or needs to do so. :-)
Maybe Uli now knows me as I kiebitzt his Comet too, although my appearance may
be a bad sign for you because his comet also fell against a nice attacking
Ikarus. :-)
What do you pay me for staying off Paderborn in June? :-)
