I also don't own a copy
I do not know if tal is weaker than hiarcs but I do not believe that it is more
than 200 elo better than it(Thorsten did not post enough games to prove it but
this is the conjecture that thorsten's results suggest)

My impression based on games and evaluations that I saw is that tal's evaluation
is not objective and prefers the attacker in unclear positions.

It does not imply that tal can be improved by using more objective evaluation
because the best evaluation to win games is not the same as the best evaluation
to predict the result.

1)The assumption that fast searchers are better at tactics is sometimes wrong

2)I think that you always have to avoid tactical errors and I am not sure if
playing in positional style when the games are long can help you.

If you play in tal's style you may discover that the game was so short that you
had no time to do tactical errors.
