Thank you and all the others for interesting results and discussion!


Last night :-)  I decided not to have any maximum of legal moves in
my program. Or more probably I set it to very high number ...
say 500. (It doesn't cost much in my program.)

I think that a working version will be ready in the end of this
year or in January. It will be freeware, and I hope it's much
stronger than Nero.

I decided to name it Alex. (My favorite player is Alekhine.) In
order to not 'blaspheme' him I'll not use version number of 1.0
but something less. (E.g. Version 0.03)   The other name I thought
for it was 'Blackout'...  :-)

My idea(?) is to search some plies full width, and after that take
into deeper consideration couple of the best PLUS some moves, which
didn't show high scores but were interesting. ( ?!- and !?-moves. )

After I have finished with this, I think I could start to learn
how Crafty is done...

I _have_ to_ do it first in my way. Many not-so-serious chess players
have had nice time with Nero. I hope that there will be use for my
new product too.
