Linus & Jo"rg both suggested that the list should accept attachments under
40K, maybe it doesn't like the filename or something? <shrugs>

I will try to sort something out later tonight - if not I will take care of
it after the weekend.

I would rather the game were technically rather than aesthetically correct
- options are nice, but menus are boring to write.

C-1 is Mr Random Move himself. But I certainly suggest you play a little
more against C-2. It would be fairer to say that (s)he plays "differently"
from C-3, rather than "poorer" - I have sat and watched them play each
other and the outcome is certainly not conclusive from the outset.

The engine works by generating a list of all valid moves and applying a
reduction algorithm to that list, currently based on weighting of
advantageous board positions - if the reduced list has multiple options,
then the perverbial coin in perverbially tossed.

I considered writing a look-ahead player, but the result is a memory-hungry
program - the perfect player is easy to write (for any game, including
chess) but the memory requirements (especially in chess) can get ludicrous
- and the calculation can take an age of Sundays.

The next problem is my (lack of) skill at the game in real life. So if you
can make any suggestions about the mistakes made by the computer - it may
be possible to create a C-4? I could reap the net for ideas - but that
kinda sucks the fun out of it.

Bwahahahahahahaaaaaa ;)

Perhaps when I add the "pass" code I can add the option for the first move
of the game to be a pass :)

Thanks for the great feedback - it's what makes it all worth while :)


PS. I think I've just had a cute idea to help the computer outwit you a
little more this space :)
