Good point although I believe she has a solid mixture of the other types of
strength--strategical and positional; she's too strong a GM to lack strong GM
skills in those arenas also.

I believe Polgar relied too much in the computer match on the her tactical
strength--in fact I think she pushed tactics to excess in both the computer and
Shirov matches.  In both cases, she would have fared better (my opinion) to
simply 'play' a more solid game and not try to blow her opponent out of the
water using landmines full of tactical powder.  Her propensities (style or
taste) for attacking play led her into deep water.  She took unnecessary risks
in both matches (although how can I criticize GM play) which may be fun for her
but gave her opponents major chances to cause her plans to backfire.  I believe
she is a much better and more rounded player than those two matches evidenced,
but her choice of moves led to her downfall--she lived by the sword and died by
the sword in both cases.

I felt she lacked playing maturity in those games, since she didn't try to take
her opponents out of their strengths but tried to brazenly beat them at their
own games (apparently she felt she was better than them at tactics).

Solid tactics come from good positions.  Many top grandmasters (not all--witness
Tal, Shirov and many others at times) absolutely shun unclear positions in which
their chances are no more in general than their opponent, instead settling for
minimal but clear advantages when ahead, trying to improve their positions step
by step, and only seeking unclear positions intentionally when losing and trying
to mix it up for counterplay.

I like viewing some tactical games live on ICC, two strong GMs going toe to toe,
since there is tremendous excitement--for a while.

However I don't like to see all games become wild melees, without finesse
(though I admit there is such a thing as tactical finesse!), where a single
unforeseen blow from the other side can end it decisively.  Although there is
certainly beauty in deep or complex tactics, there is also a rich luster to
purposeful positional and strategic play that creatively seeks to seize or
increase advantage until tactics close out the game decisively for the player
with advantage.

A mistake during positional or strategic play may not always be fatal, but a
single mistake during wild (unclear) tactics can lead to sudden loss after which
the spectator feels cheated.  Sort of like heavyweight boxing where two sluggers
go at it and one is knocked out in the first round.  Very exciting to a point,
but rather hollow when you are looking forward to a lasting bout with many
methods being tried out in the ring in a coordinated fashion, jousting back and
forth with different techniques and creative ideas, testing the will and resolve
and resourcefulness of each opponent, over and over.

I am not against tactics versus tactics, indeed that is exciting to me, but with
players that can vary their favorite style to adapt to changing conditions on
the board or in a match, the spectator is often treated with many beautiful
kinds of ideas and moves--sometimes strategic, sometimes positional, sometimes
tactical, where both opponents strive to wrest advantage in one aspect or
another, each balancing their changing options in evolving positions, trying to
maintain their footing.

As has been said, the beauty of a chess move is not how it looks on the board
but in the idea behind it.  The same applies to both strategical plans and
positional ideas as well as tactical maneuvers.  I like to see all these things
in a match between worthy adversaries.  I like to see the contestants exhibit
superskills in each of these areas, drawing on a full bag of tricks, always
trying to upstage their wily opponent who is willing to adopt a chameleon-like
approach to win a game, depending on what presents itself as the most opportune
way to seek a win.

A headfirst brawl (I can knock you out before you knock me out) pales by
comparison.  Perhaps not in a single game, but in an extended match it can
become a bit boring.

I agree.  And there is not as much pleasure in watching or playing over the
games of just two opponents.

Perhaps we enjoy the contrast of human versus computer styles so much that we
seek the enjoyment of any top competition mixing the two.  We don't want to know
just how strong is Rebel 10, but we want to know the same thing about Fritz 6,
Shredder 4, Nimzo 2000, Deep Junior, etc.  Against Kasparov, Anand, Kramnik,
Morozevich, Shirov and Polgar, et al.  We want to see the entire range of beauty
unfold in titanic battles among the great.
