Thanks for your effort!

Exactly my opinion!
Besides, I think the probability is very low that MCP7 "intentionally"
(whatever that means for a program :-) played an "anti-whoever-line"
because it's very hard to see "Oh, I must be playing against Rebel 8"
from just one (not too uncommon) opening.

My intention in publishing this game was certainly not to accuse Marty
or Sandro of any "foul play", I just found it interesting.
And I like MCP7's book much more than MCP5's.

My opinion has always been that people can put anything they like in
their opening books. If Kasparov goes into a match against Anand, he'll
think "Oh, it's Vishy, I know he doesn't like the Benkö Gambit, so I'll
play that one" or something like that. A program has no way to know
which program (or human) it's playing against, so the chances of playing
any "killer lines" are very low anyway...
