  Right.  This is precisely the, um, strategy I use when
I make all my errors.  I am deliberately failing to see
the correct move and instead playing a turkey, with
the intention of inducing a similar blunder by my
opponent.  Of course, I could always find the best
move if I really wanted to; I just *want* to play poorly.

  This is why it is rather unfair to try and judge
competitive players by how closely their moves
match up to a chess program; the program is
under no pressure to protect its title, for instance.
Nor is it ever faced with stupid questions from
reporters like- Q: "In game one, why did you allow
42.Q-g7 mate?"  A: "As world champion, I never
overlook such things.  Clearly then, I must have
been offered, and accepted, a huge bribe, of say,
ten billion dollars.  Pardon me, but I *must* get to
the bank before it closes.  The interest I'm losing
as we speak is KILLING me!"

  Because of all the hype surrounding GM Fischer
and all the controversies brought on by Cold War
politics, we seldom remember that even as BF was
taking the title from the "evil axis" in 1972, at the
same time GM Tal was undergoing a period of near
invincibility -- the streak you mentioned above.
  Countless fans of BF will recount a 6-0 match
victory or two, while never once realizing the
simultaneous exploits of GM Tal, who by the way,
"took" the year 1972 according to Chessmetrics,
over GM Fischer!

  If we go by what GM Botvinnik said, only Tigran
Petrosian never made any (combinational) errors.
(In the position after 1.e4 Nc6  2.Qh5 Nb8  3.Qxf7+,
one would be wise to decline the sac according to
GM Botvinnik's advice, if GM Petrosian has White.)

  All this shows is how closely a given player's
world championship games matched up with
move selections by a crippled Crafty.  I don't
know about you, but if I were world champion,
I would hope to be a bit stronger than crippled
Crafty, and want my moves to match up well in
simple tactical exchanges, but not otherwise.

  I really think the scope of such a statistical
analysis ought to have been limited to finding
out which world champion was the least
afflicted by a tendency to blunder, and which
was most afflicted.
