{We join game 2 when Kasparov has just played 30...Bg7-h6. With adroit
manoeuvring, Black has transformed a slightly worse position in the opening
into a very promising attacking formation in the middlegame. Garry has managed
to highlight a well-known weakness common to all chess programs: they consider
a pawn expansion in front of one's own castled king (as is the case here for
Black) a serious weakening of one's position, and thus wrongly assess the
resulting positions. This problem is hard to solve, for if the algorithm is
changed, then the computer might start sending his kingside pawns to the
attack in all sorts of positions, including those where this would amount to a
silicon hara-kiri. What makes the kingside pawn advance favourable to Black
here is the fact that the centre is closed, and although clear to a human mind,
this concept is a little loose in programming terms.} 31. Qb6 {Threatening to
take the e5-pawn due to the hanging queen on g6. A preview of what is to come..
.} Kh7 32. Qb4 {A very sly retreat, anticipating, as it were, Kasparov's
blunder on the next move. This move has no purpose in itself, and Black would
have kept a sizeable advantage had he continued with either 32...Rc8 taking
control of the important c-file, or 32...Rg8 to protect g4 and keep pushing
the pawns with 33...h4.} Rg7 $4 {An amazing howler. Garry immediately realized
his mistake after he'd played his move and kept shaking his head in utter
disgust with himself. There is no arguing that Garry is still the best showman
the chess world has to offer!} 33. Rxe5 {Suddenly Black's rook on f8, which
was defended three times two moves ago, is now found hanging. It's remarkable
that in such cases, the computer doesn't pounce on the obvious winning move,
but rather takes time as if to enjoy the moment. The few minutes that Kasparov
waited for Damocles' sword to fall on him must have seemed like eternity. I
was strongly reminded of the classic scene in "2001, a Space Odyssey", when
the cosmonaut waits in anguish for the spaceship door to open, already sensing
that the main computer has taken control and won't let him back in.} dxe5 34.

{After a calamitous opening in the third game, the computer has reached a
position with a pawn down but still not devoid of counterchances. Any human
player would have lashed out here with 21...f5 to follow up with 22...f4. If
White stops this idea with 22.g3, then 22...g5! puts ...f4 right back on the
agenda. Once again, the computer's algorithm dictates that pawns in front of a
castled king should not be pushed, especially when White's king isn't castled
on the same side. It takes human insight to see that with the center
completely blocked, not only are these pawn advances desirable for Black, they
represent the only chance to save the game. I'm surprised that the programmers
allowed their computer to enter such a closed position. What is the point of
caging such a terrifying beast behind walls where it can't make any use of its
fabulous powers? Kasparov does a perfect job of shooting down this imposing
sitting target, but truly a child could have done it.} 21... Bh4 22. Qd2 Nf6
