[comp.sys.cbm] chess programs

dickow@ui3.UUCP (01/04/87)

     I have used Sargon III quite a bit on the 64 and it is quite good, but
I think the top-of-the-line item now is ChessMaster 2000. This program has
a 3-D (viewed from an oblique angle rather than straight down) board, and
is capable of beating all the other programs around.
     I have ChessMaster 2000 for the Amiga and it is quite fine, with many
amusing touches. However, I have discovered a few 'bugs' which may or may
not appear in versions for other machines. The Amiga version called a 
stalemate after just 4 moves once (a symetric board position existed at the
time) and once it castled when the rook was threatened, which I beleive is
against standard rules.
     Have fun.

	Actually, the ruling for castling is that you cannot castle when your
KING is threatened.  Your rook has nothing to do with it.  You also cannot
castle accross check meaning if your KING has to cross a threatened sqaure
you cannot castle.  Again, your rook has nothing to do with it. (Article
6.1, second section A. Laws of Chess FIDE as amended by the Congresses to
1977.)

Boy, is MY face red! After playing chess for years, I have discovered one
more subtlety of the game. Thanks for pointing this out. I recently asked
a friend about this, and he pointed me in the right direction too. After
thinking about it, I don't think I was actually even IN the playing position
under discussion, though I knew about the King-under-threat and castling-
squares-under-threat aspects of this rule. Also, now I have more respect
for my ChessMaster 2000 as a piece of programming...I already respected
its ability to clobber me more often than not.
