First of all IBM would get out of book every game with -1.0 pawn
disadvantage (which is about the average of what Kure and Noomen
get in tournaments, sometimes they get out of book with mate in XXX even).
I would expect IBM to lose with 18-2.
Let's be realistic
a) IBM searched 11-13 ply in 97, nowadays programs search deeper
b) their book is hell worse as nowadays books are
c) positionally it never was good, it doesn't even
know what a good bishop is nor when a doubled pawn is
good (f2,g2,g3 pattern happened twice in games against kasparov)
also it exchanges sometimes queens in a position where not exchanging
wins for IBM
d) hardly can use EGTBs
So in *all* respects it is getting outgunned. Not to mention EGTBs.
No one talked about that subject yet, but last so many plies they can't
use EGTBs. They only can use them the first 5 or 6 ply, that's it.
Though this is very good compared to not using them, this means simply
that all exchanges towards a lost 5 men they will not detect.
They lose with induction to everything. The level of software has increased
bigtime when compared to 1997. Of course the strategical problems are
still there and some positional problems are still there, but in
computer-computer games you hardly can take advantage of that. Only
a human versus a computer can!
