Junior – Bezgodov 1/2
Bezgodov – Fritz 1/2

GM Alexei Bezgodov played inspired defense with little time on his clock and
gained a remarkable draw in game 1 against Junior. A nice queen sac by Junior
was trumped by even deeper calculation by Alexei, who gave up a piece to find a
perpetual check. He also showed how a practical GM can take the teeth out of a
supercomputer in game two. He gave up his bishop for three pawns to reach an
endgame that he drew against Fritz with few adventures. Very solid play that
shows how computer evaluation of material advantage in many positions is not GM
level!

Nov 8
Fritz – Janovsky (RUS) 1-0
Janovsky (RUS) – Junior 1/2

The computers scored first blood in the series when Deep Fritz scored a win
against GM Sergey Janovsky in a tough ending in which Black never equalized.
Deep Junior saved an ending that looked worse for black. 42.d6!? would have been
interesting.

Nov 9
Junior – S.Polgar (ISR) 1/2
S.Polgar (ISR) – Fritz 0-1

WGM Sofia Polgar took a page out of Vladimir Kramnik’s book (actually it’s the
other way around, she’s played this for a long time!) and played the Berlin
Defense against Junior in game 1. She defended an interesting endgame for the
draw. In game two it looked like Sofi got a little over-confident with her f4
break and then missed the nice ...Nf6! shot by Fritz that cost her a pawn. It
was all downhill from there.

Nov 10
Fritz – Belov (RUS) 1-0
Belov (RUS) – Junior 1/2

A typical computer win in game 1 for Fritz over IM Vladimir Belov. Human gets
crushing attacking chances, Fritz defends while grabbing a pawn or two, human
can’t find a win, computer wins. An exciting game! Did Belov miss a win? Game 2
was also typical, with Vladimir heading for the safety of the endgame against
Junior. Nobody had real winning chances in this one and a draw was the
predictable result.

welcome to Deep Junior Vs. WGM Sophia Polgar !; Shay: We have an exciting game
today as it follows Kasparov Vs. Kramnik in the Berlin Defense !} 13. Ne2 a4 {
Shay: Obviously Sophia had prepared this variation against DJ perhaps for the
same reasons that Kramnik did against Kasparov; Shay: Kramnik had managed so
successfully to contain Kasparov's white piece openings; Shay: with this
variation of the Spanish opening; Shay: Reason is that this variation forces
the queens offtheboard} 14. Rb1 a3 {Shay: and the game course is quiet and
strategical; Shay: computer programs tend to excel in tactics (positions with
queens) and posses less knowledge than GMs about strategic plans} 15. Nf4 {
Shay: At this position - clearly deviating from the K-K match, DJ feels
optimistic with the score of +0.53 which is the equivalent of a half a pawn
advantage} 15... Bc5 16. g4 Ne7 {Mig: Hello everyone! This is Mig back in New
York after a long month in London where we saw this defense a lot!; Shay: DJ
eval in this position is 0.80; Shay: <17. b4 Ba7 18. Nxe6 fxe6 19. Rb3 g5 20.
Kg2 Rf8 21. c4>} 17. b4 {Shay: DJ trying to gain some space here; Mig: Sofi
played the Berlin Defense, just like Kramnik did against Kasparov!} 17... Bb6 {
Mig: And just like Kramnik's plan, the idea is to get the queens off the board
and cut down on the tactical play.; Mig: A good idea against tactical players
like Fritz, Junior, and Kasparov!; Mig: Sofia is of course the middle sister
of the famous Polgar sisters.; Mig: Her elder sister Susan now lives in the US
and was/is (depending on the politics) the women's world champion.; Mig: And
her younger sister Judit is the strongest female player in history and a
regular member of the worldtop20!} 18. Nxe6 fxe6 {Shay: This is what DJ is
thinking about; Shay: <19. Rb3 Kf7 20. c4 Rhd8 21. Rbd3 Rxd3 22. Rxd3 c5>;
Shay: with an eval of +0.69} 19. Rb3 {Shay: at this position DJ is calculating
1128kN/S; Shay: which is 1 million one hundred twenty eight million positions
per second; Shay: so DJ is expecting Sophia to play Kf8; Shay: By the way, I
forgot to introduce myself, I'm Shay Bushinsky co-author of DJ; Shay: together
with Amir Ban who's not present here; Mig: The a-pawn is helpless here, as
consequence of the clever b4! by Junior.} 19... Rf8 {Shay: This experimental
version of DJ is an attempt to improve its evaluation function; Shay: it is
very different than the version that played in Dortmund Giants; Shay: We had
to do something about getting killed by the super GM chess e.g. Kramnik and
Piket; Shay: who applied innovative systems - setups against us successfully;
Mig: Sofi and her husband make a rather high-elo couple. He's GM Yona
Kosashvili.; Shay: DJ's eval dropped a bit after Sophia's Rf8: 0.62} 20. Rdd3 {
Shay: I've read Mig mentioning Yona, he's not only a strong grandmaster but
also a computer killer; Shay: he's notorious for winning the AEGO man-machine
tournament 6 wins out of 6 games against strong computer programs!; Shay: DJ
is expecting now Ra4 looking more like a computer move than a human's move;
Mig: It looks to me like DJ is going to be up a solid pawn, and black doesn't
even have the usual two-bishop advantage common in this defense.; Mig: But in
such an ugly, blocked position it may be tough for a computer to make progress
in the ending.} 20... Ng6 {
Mig: This will allow Sofi to connect her rook by lifting her king.} 21. c4 c5
22. bxc5 {Shay: ********************} 22... Bxc5 {Shay: ***********************
************; Mig: Hmm, Deep Junior appears to have fallen asleep on the * key.
; Shay: yeah just snoring; Mig: That should be the ZZZZZZZzzzzzzzzzzz key.} 23.
Rxb7 {Mig: It looks like DJ found a breakthrough. Computers don't like to win
long, slow endgames! I don't even think they know such endgames exist!; Mig:
Sofi will have white in the next game against Deep Fritz.} 23... Nh4 24. Nxh4
Bxf2+ 25. Kg2 Bxh4 {Mig: tactics! Sofi counterattacks with a temporary piece
sacrifice.; Shay: so sorry for the laps I'm back with the following; Mig: But
black's pawns are still very weak.; Shay: <26. Be3 Rf7 27. Rbb3 Rd7 28. Bc1
Rxd3 29. Rxd3 Ke7>; Shay: +(0.55); Shay: eval dropping +(0.44)} 26. Be3 {
Mig: Interesting, Junior refuses to grab either of the pawns on offer and
instead develops a piece! Probably afraidofRf2+} 26... Rf7 {
Shay: <26... Rf7 27. c5 Rd7 28. Rc3 c6 29. Rb6 Rc7 30. Bf2 Bg5>} 27. c5 {

31. Bd4 Bh4 32. Rd3>; Shay: +(0.26); Mig: This has turned into a very sharp
endgame. Sofi is going to have to work hard to hold the position together.;
Mig: Junior's evaluation has dropped to almost even, but that's because it
expects Black to play like it would!} 28... Bd8 {Mig: over-protection! The
weakest point in the black position is the c7 pawn so Sofia cracks down.; Mig:
If she defends all the obvious weak points it is very possible that Junior
won't be able to find a plan.} 29. c6 {Shay: <29. c6 Rd1 30. Rc3 Ra5 31. Kg3
Rxe5>; Shay: +(0.50); Mig: That's the biggest weakness computer have versus
humans in my opinion. Inability to plan for the long term in endgames.} 29...
Rd1 30. Rc3 {Mig: A human might see a two vs. one pawn race on 20 or 30 moves
down the line, but the computer has to calculate it all.} 30... Ra5 31. Rb8 {
Mig: Sofi has finally activated a piece! She was threatening Ra1 so Junior
prepares to put its rook on c2 to defend.; Mig: A pin on the bishop. Bb6! is a
strong threat.; Shay: <31... Rad5 32. Kf3 Rxe5 33. Bf4 Rf1+ 34. Kg3 Ree1 35.

in extensions)} 32. Bc5 {

32... Kg6 33. Rc2 Rd5 34. Bd6 {Mig: Ouch! that's the same sacrifice we looked
at before, but here it's on d6 instead of b6!; Mig: But really it's just a
pretty way to exchange bishops.; Shay: <34... cxd6 35. Rxd8 Rdc5 36. Rxc5 Rxc5

okay. But it's always a shock to see a move like that!} 34... cxd6 35. Rxd8

so this is a draw.} 48... Ra7 {Frederic: All I'm asking for, and that ain't
much, is a recount!; Mig: Sofi just has to move her rook back and forth and
Junior can't make progress.} 49. h5 {

down to 795!; Mig: By the rule of "no demonstrable progress". It looks like
Sofi has a slippery mouse, one of the dangers of online chess!; Frederic: The
game is a draw. Ah, the retraction is there...; Mig: Good sportsmanship from
Junior and its operator, but the public would not have stood for that!;

solid position here, the question is whether or not Sofia will play for a win
against the machine or be happy with another draw.; Mig: The tendency so far
in the series is for the players to not risk too much against the ChessBase
monsters!; Mig: So far there have been four draws and one win by Fritz against
GM Janovsky.} 12. b4 Nb6 {
Mig: Sofi follows a general rule: when your opponent lets you, grab some space!

white's expansion with a pawn push on the queenside, but computer usually
prefer to play with their pieces.} 13... dxe5 14. Qb3 Be6 {Frederic: Hello,
anyone home?; Mig: Fritz focuses on the weak c4 pawn. The position is about
equal.; Frederic: White is 19/100ths of a pawn up.; Mig: White still has her
small advantage in queenside space. If the rooks all come off on the open
d-file not much is going to happen!; Mig: Perhaps Sofi could use her bishop
pair in that case, but the e5 pawn is annoying.; Mig: I worked with Sofi our
Herzlia office for seven months while we were designing the site. She learned
web design very quickly!; Frederic: The question is which rook moves to the
d-file on the next move?} 15. Na4 {Mig: Now she's spending a lot of time
making KCU multimedia lessons. Hers are some of the most popular.; Mig: Sofi
moves to grab the c5 square made available because the black knight is
blocking the b-pawn.} 15... Nbd7 {Mig: 12...Nb6 looked superficial, as I said
at the time. Now maybe Nfd7?; Mig: Aha! Fritz admits its mistake!; Mig: Now b5
is a threat because the c4 pawn is pinned by the bishop.; Mig: When we asked
Sofia to play against the killer machines she said, "Oh great, what did I ever
do to you?!"} 16. Qc2 {
Mig: But she's more than holding her own here, as you can see.} 16... Bg4 {
Mig: Players have adapted to the computer style over time and in a 60-min game
they can do quite well.; Mig: Deep Junior mauled top GMs Illescas and even
top-10 Michael Adams at this time control, but GMs learn from their peers'
experiences!} 17. Bxg4 Nxg4 {Frederic: Sophia is quite a killer herself --
cute and gentle as anything off the board, a chainsaw killer over it.; Mig:
I'm really looking forward to seeing GM Boris Alterman face the programs in a
few days, Frederic.; Frederic: Remember Rome, many years ago, where she scored
the highest performance ever in the history of chess.; Mig: He works with the
programmers to tune Junior and its book and knows all of the program's tricks.
Plus he was 2600+ when he was active.; Frederic: Boris Alterman is a problem,
he understands the machine extremely well.; Mig: He will be a serious test for
the programs.; Frederic: Sophie will play 18.e4.} 18. h3 {Mig: That's what
your Fritz is recommending, but it's a passive move in the long term. Solid,
but passive.; Frederic: Dang!; Mig: Right!; Mig: The e4 square might be a nice
home for the white knight, and she wants to keep the position a little more
open for her bishop.; Mig: But e4 might be required by white at some point if
she can't prevent the same move by black.} 18... Ngf6 {Mig: If Fritz can play .
..e4, then e5 is a great square for its knight.; Frederic: No more prediction
(except that she's going to play a rook to d1)} 19. c5 {Frederic: No more
predictions!; Mig: Frederic, give it up! Aren't you the one who said Nader was
going to win the election?; Mig: No more predictions from you.; Frederic: The
next election in the US we are sending UN observers...} 19... Red8 {Frederic: M
ig, the position is fairly open (good for Fritz) but fairly solid (good for
Sophia).; Frederic: Is Sophia sitting in the office of KC? Is Deep Fritz in
the same room?} 20. Rad1 Nf8 21. f4 Rxd1 22. Qxd1 Rd8 {Mig: White grabs some
more space, just like we talked about.; Frederic: Is 23.Bxe5 possible?!
Probably not.; Mig: They are both in the Herzlia office, Fred. But not in the
same room.} 23. Qa1 N6d7 {Frederic: That's good. Then Fritz can hum.; Frederic:
Fritz played instantly because it was expecting Qa1 and had already calculated
a reply.; Frederic: My Deep still thinks White is slightly better.} 24. Rd1 {
Frederic:} 24... exf4 {
Mig: Okay, things are getting tactical now. The g7 pawn is under fire.} 25.
Bxg7 fxe3 26. Rd6 {Mig: That's usually nto a problem for Sofi Polgar, her
tactical skills are still sharp even though she doesn't play too much these
days.; Frederic: Oops, that may not have been good...; Frederic: Now 26...e2;
Mig: She's expecting a baby next month, which could explain things...; Mig: ...
e2 looks very strong. Maybe she should have kept the rook back to defend.}
26... e2 27. Bh6 {Frederic: That pawn on e2 is going to be troublesome.; Mig:
Threatening mate in one, but I think Fritz will notice!; Frederic: Omygod, we
forgot the mate detect code!; Mig: Frederic Friedel is here commentating from
Hamburg, Germany. He is one of the directors of ChessBase, the company that
publishes Fritz and Junior.; Frederic: 27...Nf6, but will Fritz see it?; Shay:
<27... Nf6 28. Nc3 Rxd6 29. cxd6 Qxd6 30. Nxe2 N8d7>with a pawn up for black;
Shay: -0.78} 27... Nf6 {Mig: Right, the c-pawn will be lost. Still good
drawing chances for Sofi, though.; Frederic: Fritz say: Hallo Kolleague from
Israel. What do you think of these humans?; Shay: Humans are usually nice
people to para George W. Bush Frederic :); Frederic: Fritz: I think I'm going
to eat a pawn on d6...; Frederic: Fritz: Humans are great, but they are so
sloooooooow.; Mig: You can actually buy Fritz and Junior from the ChessBase
store here at KC. Along with ChessBase 8 all the pros use this software.; Mig:
But I'm sure Sofi isn't too happy with it right now!; Shay: yes Sophia played
a very good game but missed the nasty Nf6!; Mig: If Qxf6 threatening mate,
then e1Q+ Kh2 Ne6 kills the threats and wins.; Frederic: Who's annotating with
DJ? Shay? Boris?; Mig: And if rook takes knight, then Rd1+ wins immediately.;
Shay: Shay here; Frederic: Fritz: Obviously! Simple tactics.; Frederic: Hi
Shay, I hear the beastie has four 500 MHz processors.; Shay: eval now -0.76
(this is Deep Fritz's eval); Shay: That is correct Frederic!; Frederic: Can
you give us a node count?; Mig: (That's how many positions per second for you
normal people out there.); Shay: Node count is 1222KNpSecond; Frederic: That's
one point two million positions per second, folks!; Shay: It means Deep Fritz
can count the Florida vote in 6 seconds!; Frederic: And get it right!} 28. Qe1
{Mig: Hey now, just because the US education system eliminated counting from
the curriculum a few years ago...; Frederic: You know that 99.99999% of
everything Fritz looks at is JUNK. That's the way programs work.; Mig: Hmm, it
looks like this could get messy. Nc3 looked essential.; Shay: It does require
that the humans sign their votes correctly on the form} 28... Rxd6 29. cxd6 {
Mig: Now the pawn is lost anyway, but the knight is still in limbo on a4.;
Shay: <29... Qxd6 30. Qxe2 Qd4+ 31. Kh2 Ne6 32. Nb2 Qd6+>; Shay: -0.91} 29...
Qxd6 30. Qxe2 {Shay: Fritz sees very little compensation for the extra pawn it
posses; Mig: A solid pawn advantage for Fritzy. Can it convert the point?; Mig:
Having a bishop is a little compensation with pawns on both sides of the board.
; Frederic: With queens on the board it should normally be a wizz.; Shay: to
Fritz's advantage the board is open for its queen; Mig: And we've seen the
machines be vulnerable in endgames. But with queens still on it looks tough
for Sofi.; Shay: Hey Frederic stop thinking what I'm thinking; Mig: You guys
both think like your programs, that's the problem!} 30... Qd4+ {Frederic: But
you know I've seen plays of this caliber do incredible things. Look at the
first round, with two miracle saves.} 31. Kh2 Ne6 {Shay: <30... Qd4+ 31. Kh2
Ne6 32. Nb2 Qd6+>; Shay: -0.88; Frederic: Another problem dear Sophia has is
the two knights. Fritz will keep threatening 13-move forks.; Mig: You can also
watch the Human-Machine games in the KC Playing Zone if you like to chat with
other spectators.; Mig: Yes, years ago GM Bent Larsen said that if you take
the knights off the board the computers drop 200 points in strength!; Shay:
Yona Kosashvili the computer killer kibitzes here Qe3; Mig: It's just that for
a human, the knight move is not geometrical and it's harder to visualize than
bishops and rooks.; Frederic: One of the problems humans face is that these
monsters keep threatening minor tactics EVERY single move of a game.; Shay:
Not that he would play it against a human but exchanging the queens here would
help his wife!; Mig: But for computers, seeing a seven-move knight combination
is no problem.; Frederic: And for computers the knight is the easiest piece
(nothing can block it).} 32. Nc5 {Frederic: When the first computer program
was written to play chess, in Los Alamos about 50 years ago, they did it for a
6x6 board. They left out the bishops, because they were so hard.} 32... Nxc5 {
Frederic: Poor Sophie, it's all over (after Nc5)} 33. bxc5 {Mig: Sofi realizes
that she has good chances of forcing a perpetual check draw if she can
distract the black pieces away from the king. Fritz might not realize that...;
Shay: <33... Qxc5 34. Qf3 Qe5+ 35. Bf4 Qe4 36. Qg3+ Qg6>; Frederic: Deep Fritz
has routines to detect that (theoretically)...; Mig: As we saw in the game 1.1
with GM Bezgodov, that sort of repetition draw can be easily missed by a
computer. That was Junior though. Fritz is different?} 33... Qxc5 {Shay: -+1.63
; Mig: Hmm, I don't see much real compensation, but black's open king gives
humanity hope!; Frederic: My program is going down 14 ply, with 35-ply
extensions, and seeing no perpetuals.; Shay: This is very psychological -
Sophie felt too confident and played f4 for the initiative; Shay: then she
blundered the Nf6 which can happen to every human; Frederic: Yeah, it's a
shame. People have to avoid daring, attractive moves against computers.;
Frederic: In Dortmund the world's top players were not playing anti-computer
chess, they were playing anti-chess. That got them 50% against the machine.
Not pretty, but effective!} 34. g3 {Shay: well, to be honest, it wasn't bad to
play for the initiative but need to play with 7 eyes} 34... Qh5 {Shay: -+ 1.97}
35. Qxh5 Nxh5 36. g4 {Frederic: Fritz: Kolleague DJ, I think too 1.97
precisely; Mig: Nice shot by Fritz. The Queen exchange was forced and now it's
pretty much over.; Shay: <35. Qxh5 Nxh5 36. g4 Nf6 37. Kg3 Ne4+>; Mig: If
Sofia had played Qd2 then Ng4+! won.} 36... Nf6 {

for Sofi. She was a good sport to play with so many other things on her mind

ChessBase in Hamburg.; Frederic: Belov has decided to play a different
strategy against Deep Junior: keep the position simple, avoid dangerous
tactics, rely on superior human strategic understanding.} 18. f4 Bd7 {
Frederic: I've been studying the previous game against Fritz. I'm convinced
Belov could have won that one.} 19. f5 {Shay: <19. h4 h6 20. f5 Bc6 21. Nc3

computers. Deep Fritz thinks White has half a pawn advantage.} 23... b5 {
Frederic: Deep Fritz is a new ChessBase program which runs on up to eight
processors. My machine has just one, but DF is hitting around half a million
positions per second on it.} 24. b3 {Shay: <24... b4 25. g3 Nc6 26. gxh4 Ne5+

with the recount in Florida.} 26. Bf2 {Shay: <26... Kd6 27. Kd2 Bh5 28. g4>-0.

bishop moves around and does nothing.} 40... Be7 41. Bf2 {
