World news: Kasparov-Fritz The match is tied at 1.5-1.5 after three interesting games - and just one more to go.
In game 1, Kasparov won the exchange but "X3D Fritz" obtained counterplay and the first game of their match ended in a draw by perpetual check.
Kasparov blundered a crucial pawn in a good position and then resigned as the computer program forced game 2 into an endgame in game 2. But the world's top-rated player bounced back to easily win the third game, playing textbook "anti-computer" chess - obtaining a huge space advantage early in the game, patiently winning a pawn, and avoiding all possibilities of a tactical skirmish in which the computer might find surprising resources.
The New York match is taking place in X3D "virtual reality" with the on-screen board "floating in the air" in front of Kasparov. His moves are received by X3D Fritz via voice recognition and appear instantly on the display screens. Kasparov recently drew a match against another computer program, Deep Junior, and famously lost a match to IBM's Deep Blue some years back.

Game 3: Kasparov-X3D Fritz 1-0
1.Nf3 Nf6 2.c4 e6 3.Nc3 d5 4.d4 c6 5.e3 a6!?
A popular idea lately, which allows black to play ...b5 in some
lines
6.c5!?
A fairly fashionable response, gaining space
6...Nbd7 7.b4 a5 8.b5!?
A very interesting way of dealing with things. White already has a
considerable space advantage on the queenside, and the a5 will become
vulnerable. The problem for black is that any attempt to secure a5
with ...b6 will allow either bxc6 or c6 by white, with a deadly passed
pawn. This position has some strong affinities with the Ne2 line of
the Rubinstein Nimzo-Indian, where white's queenside play is harrd to
answer.
8...e5!?
Black will need to get this in at some stage, but maybe simple
development with ...Be7 and ...0-0 was better first. If 9.Nxe5 Nxe5 10.dxe5 Ng4 will recover the pawn and weaken white's grip
9.Qa4 Qc7
Defending c6
9...cxb5 10.Bxb5 exd4 11.exd4 Be7 12.Bf4 O-O 13.O-O is very strong
for white. Black's pieces can hardly move, it's hard to defend d5, and
the threats include c6!?, eg 13...Re8 14.c6 Nb6 15.c7!! Nxa4 16.
cxd8=Q Rxd8 17.Bxa4 +-
10.Ba3
defending c5
10...e4?!
A book move, but it looks dodgy to me. Closing the pawn structure limits black's possibilities for
counterplay. Now black's only option is kingside play, but he never
gets around to it
11.Nd2 Be7 12.b6!?
Very committal - and apparently a novelty. It's now almost certain that white will win the a5
pawn with Nd2-b3-a5, but the resultant pin is briefly awkward. White
also has a huge space advantage on the queenside, which is so blocked
that black has no prospects there at all. Blocking the position, in
general, is a good tactic against computers since they play such
positions quite poorly.
12...Qd8 13.h3 O-O 14.Nb3 Bd6?
A cheap trap, but otherwise completely pointless, it seems, in view
of the bishop's retreat next move.
15.Rb1!
A good move, giving added support to the b6 pawn in the event of Na5.
It avoids some nasty tactics:
15.cxd6?? Nxb6! winning the queen, or
15.Nxa5? Nxb6!! 16.cxb6 Bxa3 17.Qxa3 Qxb6 18.Nc4? dxc4!! 19.Qxa8 Qb2
20.Rd1 Qxc3+ 21.Rd2 Qc1+
(21...Bg4! is even stronger, eg 22.Qxf8+ (22.Qxb7?? Qc1+ 23.Rd1 Qxd1#) 22...Kxf8 23.hxg4 Nxg4 24.Rxh7 Nxf2! -+)
22.Rd1 Qxd1+!! 23.Kxd1 Bg4+! 24.hxg4 Rxa8 25.Bxc4 Nxg4 26.
Ke2 b5 27.Bb3 is one possibility, illustrating some surprising
tactical possibilities
15...Be7?!
Given the last move, ...Bb8 might be better to keep the e-file open
for ...Re8. Black is lost on the queenside and its only hope is to get
...f5-f4 in - paradoxically, attacking in front of its king. In that
respect, the position now resembles some lines of the Saemisch King's
Indian
16.Nxa5 Nb8?
Too slow. There is some point to the move, which secures c6, since
otherwise white could try Qb4/Nxc6!/b7. But better was
16...Ne8
17.Bb4!
Overprotecting the Na5 gives the queen freedom to graciously
reposition herself. In contrast, breaking the pin with Qb4?! would
leave the queen misplaced and the Ba3 could be vulnerable
17...Qd7? 18.Rb2!?
Kasparov plays super-cautiously, overprotecting f2 and a2
18...Qe6? 19.Qd1 Nfd7!
Threatening 20...Nxb6! 21.cxb6 Bxb4 and 22...Rxa5
20.a3! Qh6!? 21.Nb3 Bh4?
Better ...f5 and ...f4 first
22.Qd2 Nf6? 23.Kd1!
A king march in the Steinitzian fashion
23.g3 Bg5 24.h4 Ng4 would give black counterplay
23...Be6?!
Not particularly useful, as the bishop on c8 slows up any a6 advance
24.Kc1 Rd8?
Black should be preparing ...f7-f5-f4
25.Rc2 Nbd7?
...Na6 would presumably be met by Bxa6 followed by advancing the pawn
to a5 and repositioning a knight to b4
26.Kb2?! Nf8 27.a4 Ng6?
Black dumbly assembles pieces on the kingside, even though it's
obvious to any human observer that they've got nothing to do
28.a5 Ne7 29.a6!!
The breakthrough
29...bxa6 30.Na5! Rdb8 31.g3 Bg5 32.Bg2
threatening h4 and opening the way for a rook shift
32...Qg6 33.Ka1 Kh8 34.Na2 Bd7 35.Bc3 Ne8 36.Nb4
White focuses on a6
36...Kg8 37.Rb1 Bc8 38.Ra2 Bh6 39.Bf1 Qe6 40.Qd1
From here the white queen can go to a4 if needed
40...Nf6 41.Qa4 Bb7 42.Nxb7 Rxb7 43.Nxa6 Qd7 44.Qc2 Kh8 45.Rb3 1-0
Black can do nothing to stop the long-term advance of the b-pawn. A
game which amply demonstrates the limitations of computers!
