Ok sorry for this. I have never heard of anyone, human or program that easily
wins over in example Fritz or Tiger with cheap tactics and then dumps the
program or version.

Compare Fritz, Shredder, Tiger and Junior, 4 of the best programs. Which
programs are weak positionally and which programs are better than them
positionally. Tactics don't come right from the air it comes from the position
and sometimes the book.

He wasn´t impressed of a program that was superior in the most popular opening
in the world. He wasn´t impressed of the result 60 % against one of the best
engines in the world?!

Ok he wasn't confused, he was schocked both in game 3 and 5. Bxh2 was probably a
positional mistake but the tactics was so complicated that he was afraid of
them. If you had played another top-program I believe all odds are on white.

That is exactly what everyone means, that castling right in to the attack are a
bad positional move, it is cheap tactics if you can survive in a bad position.
Maybee you have another definition of positional play than everyone else.

Many have played out this line and the results clearly favors white. White was
better. I believe almost everyone believes white was clearly better but missed
tactically.

If so it seems that this is the only point i´m wrong.
