Fritz vs Junior – Game four
Game four repeated the opening from game two, with Fritz playing 1.d4 and Junior
replying with the sharp Grunfeld Defence. White deviated from the second game
with 16.f5 instead of 16.d6. Fritz liked the position, showing a high score
of more than one pawn for the next ten moves. But from then on it went downhill.

Ba5 16.f5 Bxf5 17.Rxb7 Qd6 18.Bc4 Qe5 19.Rf3 Rab8.
Deep Junior decides to sacrifice a pawn, allowing Fritz a long term passer
but gaining a rook attack in compensation. 20.Rxa7 Bb6 21.Ra4 Bc7 22.g3
Rb1 23.Re3 Qf6 24.Ra6 Bd6 25.Re1 Rfb8 26.Bf1 h5 27.a4 c4. A second
pawn sacrifice, which was accepted by Deep Fritz. This allowed Deep Junior's
second rook to penetrate White's position. 28.Rc6 Ra1 29.Bxc4 Bd7 30.Rf1
Qe7 31.Rxd6. Deep Junior's active piece play has forced Deep Fritz
to sacrifice an exchange. 31...Qxd6 32.Qf2 Qb6
33.Bf4? Fritz lost game four after committing a serious error:
33.Bf4 is losing. Instead 33.Be3 Rxf1+ 34.Bxf1 Qb1 35.Qf6 Bh3 36.Bd4 Kf8= (36...Qxf1+
37.Qxf1 Bxf1 38.Kxf1 +/=) should be a draw. [Alexander Kure of the Fritz team.]
A critical moment in the game. This move allows Deep Junior a favorable queen
exchange while leaving Deep Fritz's king exposed to threats from the two black
rooks. Fritz is forced to defend its king and its pieces, while Junior starts
to push its king side pawns. [Shay Bushinsky of the Junior team]. 33...Qxf2+
34.Kxf2 Rb2+ 35.Ke3 Rxa4 36.Bd3 Rxh2 37.c4 Ra3 38.Kd4 h4 39.g4 Rh3 40.Be2 Rhb3

The loneliness of a long distance chess programmer: Alexander Kure of Austria
arrives early to prepare Deep Fritz for game four.

Deep Fritz is running on an eight-core machine out of Hamburg Germany. The
program is searching 13-14 million nodes per second, reaching a search depth
of 20-21 ply. Deep Junior, playing out of London England, is employing the latest
Intel Server technology with 16 cores. The program is running at 24 million
nodes per second and consistently reaching search depths of 24 ply.

They are dressed in national costumes of exotic beauty. But what are they here
for?
They are going to follow the computer moves on the display board
You will have to forgive your photographer for losing all restraint over these
kids
The programmers are just as bad: everyone, like Shay Bushinsky above, wants
his picture taken with the chess board operators

from him

The game starts, with the girls executing the moves displayed on the computer
screens on the official board.
You can tell that these girls are competent chess players by the way they
immediately grasp the moves displayed on the computer screens, and the smart
click-and-switch motion in which they capture pieces on the board.

Champion for under eight, under ten, the World Championship under twelve and
the European Championship under 14. Sanan is already a full IM.
Things are looking grim for Fritz, which has been searching at 12 million
positions per second
