Yesterday there was a hot discussion abouth the strenght of chess computers. I
said that no program has more than 2500 ELO and that "weaker" players can fight
with good chances to draw and that I could not understand why the GM's do so
hard against the computers. On the other hand I tried to find some explanation
for that. Below now my last ten games, four times a loss and six times a draw,
that means a score of 30 percent.
ChessBase7 says:
Average rating Utzinger = 1978 ELO (performance = 2341 ELO)
Average rating computers = 2490 ELO (performance = 2127 ELO)
And now the games with my comments.

Unexpected for me, Gambit Tiger 2 was already out of book.} 4. Nf3 Bg4 {
If Black plays this move he must be ready to give up the bishop pair.} 5. h3
Bxf3 6. Qxf3 e6 {Looks dangerous in view of the weakness on the dark squares
in Black's camp. But sooner or later Black cannot avoid e7-e6. The idea is to
poste my Bf8 on e7 instead of at g7. I had made the experience in this kind
of position that Black - after Bf8-g7 - is later often forced to bring his B
back to e7. So why not at once? All this may be become more clear in the
ensuing comments of the game.} 7. Nd2 h5 {In my opinion no waste of time.
Black intends to prevent g2-g4 and is planning h5-h4 at the right moment in
order to let follow the maneouvre Ng8-h6-f5 or Ng8-e7-f5.} 8. Nb3 Nd7 {
With pressure on e5 thus not allowing the enemy knight to go to c5.} 9. c3 {
Instantly played.} 9... Be7 10. Be3 Nh6 11. Bd3 {Gambit Tiger 2 played this
and the following three moves instantly. I didn't like that.} 11... Nf5 {
A good place for the knight.} 12. O-O Bg5 {
Due to a lack of other ideas I decided to exchange bishops.} 13. Rad1 {
Having already used 20 minutes on the clock I became nervous and again "lost"
four minutes to find a suitable plan.} 13... Bxe3 {Another trial was the
waiting move 13...Qe7 that, fairly spoken, did not come to my mind.} 14. fxe3
Qg5 15. e4 Qe3+ {Exchanging Q is not a bad policy against a dangerous attacker
like Gambit Tiger 2.} 16. Kh2 Qxf3 17. Rxf3 {

17... dxe4 18. Bxe4 O-O-O {
Doing something for the development and defending the pawns on the queen wing.}
19. Rc1 Kb8 {I was not unhappy with the situation: the Nf5 has a strong
position and White's king side is more or less blocked whereas on the other
wing it should be possible to build up a sufficient defence.} 20. Rf2 h4 {
Preventing g2-g4 for ever. On the other hand the advanced pawn may become weak
should White succeed in placing the rook on f4 and the his knight to f3.
Nevertheless played I this move automatically as it seemed to be the "correct"
one.} 21. Na5 {Is 22.Bxc6 bxc6 23.Nxc6 Kc7 24.Nxd8 a threat? I had no time to
investigate and so I took the rook to defend c6. It was of course also
possible to reply with 21...Kc7, but I feared that White could break up the
c-file.} 21... Rc8 22. Rb1 Rc7 {Passive defence instead the active
continuation 22...f6, a move for which I had not thought a moment.} 23. b4 Rhc8
{Again played very fast in order not to loose the game on time. White's clock:
21:03, Black's clock: 30:28} 24. Nb3 {Is this really the best move? I was just
thinking about how to answer 24.Nc4 when White relieved me.} 24... Rh8 25. Nc5

b-line will not become dangerous, I decided to exchange the knights.} 26. bxc5

Rebel Tiger II-GUI } 1. e4 c5 {The first two games against Gambit Tiger 2.0
ended with a draw. So I made a trial to play the sharp Sicilian defence.} 2.

understand that the program played this - in my opinion - rather harmless
continuation.} 3... d5 4. exd5 Qxd5 5. d4 Nf6 6. Na3 a6 {Already being out of

more than 80 seconds.} 12. dxc5 Bxc5 13. Qxd5 {Indeed somewhat surprising that
Gambit Tiger is exchanging queens. The anti-human option has obviously too
less influence in this situation. Never had I expected this move.} 13... Nxd5
14. Bg3 {Up to now it was very easy to find good moves. In spite of the
missing queens this middle game position is very tricky. Where are the best
places for the own pieces? What pieces should be kept on the board? And what
about the pawn structure? White has a pawn majority on the queen's side that
can become very dangerous. I knew from experience that only utmost attention
on my part could avoid an unnecessary disaster.} 14... N7f6 {Nearly 10 minutes
went over to form a suitable plan. And in such positions you need a plan. The
strategy "to play from move to move" seldom works. With Nf6 my well posted Nd5
is protected. Furthermore Black looks for Nf6-e4 to obtain the pair of bishops.
And eventually the rooks obtain good perspectives on the squares c8 and d8.}
15. Nfe5 Rfd8 {The line mentioned below is perhaps even stronger. But after 15.
..Nf6-e4 I had no good idea how to anwer 16.Bg3-h4 and so I put the rook to d8
to avoid Ne5-d7.} (15... Ne4 16. Nd7 Nxg3 17. hxg3 Rfd8 18. Nxc5 bxc5 19. Bf3)
16. Bf3 Rac8 {A fast and logical decision.} 17. Rfd1 Ba8 {Now the pin Bf3-b7
is neutralized. In most cases it is a good policy to let have the own pieces
protected.} 18. Kf1 {For me a rather difficult situation. My pieces are
optimally placed and the question is: what to do without weakening the
position?} 18... Kf8 {In the analysis after the game, using the ChessBase-GUI,
Gambit Tiger suggested 18...Nd7 a good move that I had not even considered. I
was about to play 18...a5 when I changed my mind. To centralize the king looks
sound.} ({Gambit Tiger 2.0:} 18... Nd7 19. Nxd7 Rxd7 20. Rd3 Rdd8 21. Rad1 b5

equal, it seemed to me that White has somewhat improved his position. Anyway,
I was unable to find a clear way to neutralize White's small but sensible
advantage. Fortunately, I had enough time to study the position more deeply.
And this was good because at first glance I wanted to play 25...f6 until I
perceived the strong answer 26.c4.} 25... Bc7 (25... f6 26. c4 bxc4 27. Nxc4

28. Bg3 {Again an important moment. White threatens to play Rb7 and my first
idea 28...Rc8 29.Rb7 b4 does not work as White plays 30.Bd6 and not 30.cxb4.
This is a typical example where a computer sees the correct move 28...Ne7 at
once wheras human beings need some time to come to the same conclusion.} 28...

followed by b2-b4 and Bf2-c5 when it will no longer be possible for me to
defend the b5-pawn. What can I do against this plan? The question was whether
White's position really was so overwhelming as to yield a win without any
difficulty. Wherein then do Black's chances lie? I came to the conclusion that
only a rook ending may save the game and so the following moves are more or
less forced.} 31... Ng6 32. Ke3 {

ending that stands outstandinlgy better for White. The main trump of GT_2 is
the pawn majority on the queen's wing allowing to create a passed pawn. These
were my thoughts during the game. Only afterwards did I realize that the
situation was less worse than imagined.} 35. g3 {Most surprising and
unexpected allowing Black to change the pawn structure in a positive manner.
Before this move a pawn ending would have been an easy win for Gambit Tiger.
This is now no longer the case and so I think it is not wrong to give the move
35.g3 a question mark. This is the more correct as 35.g3? makes White's
f3-pawn rather weak. And as long as White has no passed pawn it will seldom be
possible to give up pawns on the king's side.} (35. b3 Re5+ 36. Kd3 Rd5+ 37.

in this phase.} 38. Ke3 (38. Rh7 Rd6) 38... Kg8 {
So White's rook cannot go to h7.} 39. c4 bxc4 40. bxc4 Rd1 {For me the only
move. Black must not allow the opposite king to support the strong passed

because it seemed to me that White should be able to win the ending. So my
only aim was to search for some way in which Black can pose a problem to GT_2.

{White: Yace 0.99, own book Hardware: P_III 800/128, 32 MB hash Time Control:
40'/40+40'/40+40' } 1. e4 c5 2. Nf3 e6 3. c4 {Throws me "out of book".}
3... d6 4. d4 cxd4 (4... b6 5. Nc3 a6 6. Be2 Qc7 {
would not have been a bad plan against a computer.}) 5. Nxd4 Nf6 6. Nc3 a6 7.
Be2 Be7 8. O-O O-O 9. Be3 {White last book move} 9... Qc7 10. Qc2 Nbd7 {
Not knowing this kind of position, I had no idea wether the knight belongs to
d7 or c6.} 11. Rfd1 b6 12. a4 Bb7 13. a5 {An unexpected move for me.} 13...
bxa5 14. Nb3 Nc5 15. Bxc5 dxc5 16. Nxa5 Rad8 {At first I wanted to move the
other rook to d8, but then saw at once: Black would be lost.} (16... Rfd8 17.
Nxb7 Qxb7 18. e5 Nd7 19. Bf3 {and White wins material}) 17. Nxb7 Qxb7 18. e5
Nd7 19. f4 Nb8 {A move I had taken into consideration was also 19...g5 but
then I had not the courage to play it. So I returned my knight to b8 with the
intention to defend pawn-a6 and to play later on Nb8-c6-d4(b4).} 20. Bf3 Qc7 {
Exerting pressure on e5 to prevent White's f4-f5 as long as possible.} 21. g3 {
Looks rather slows to me. By exchanging rooks and placing my knight into a
much better position I now wanted to obtain at least equal chances.} 21...
Rxd1+ {
There was no need to exchance rooks. The immediate 21...Nc6 was also possible.}
22. Nxd1 {Very unusual, but not at all a bad move. If White had replied 22.
Rxd1 so 22...Rd8 and further exchange is almost impossible.} (22. Rxd1 Nc6 23.
Be4 Nd4) 22... Rd8 23. Ne3 Nc6 24. Qg2 {This move had escaped my attention.} (
24. Rxa6 {would have been a mistake} 24... Nb4) 24... Nb4 25. Qe2 {Black has so
far played a good game and White has slight advantage only. But instead of
keeping the position quiet, I suddenly hastend to force things by opening the
long diagonal for Black's bishop. For reasons beyond my control I had
completely overlooked White's 27th move.} 25... f5 26. exf6 Bxf6 27. Ng4 Bd4+
28. Kh1 {It looks not yet worse but Black must be very carefully to not get in
a very bad position.} 28... Re8 {Follows a completely wrong plan to play e6-e5.
} (28... Rd6 {was of course the correct defence and it's not easy for White to
improve the position.}) 29. Be4 g6 {Against f4-f5 and preparing the next move
to put pressure on the diagonale h8-a1. On the other hand the pawn move
weakens Black's kingside.} 30. h4 Qg7 31. Rb1 {And now I had no much time left
on my clock and so the game continued in the normal way: Black begins to make
various inaccurate moves and Yace_099 wins without problems.} 31... Kf8 32. Bg2
h5 33. Ne5 Bxe5 {And this is the decisive mistake although White's position
was in any case much better.} 34. fxe5 Kg8 35. Qe3 {Attacking a weak pawn.}
35... Qe7 36. Rd1 {Occupying the open d-line with the threat 37.Rd6. Black has
no defence and the following mistake makes things clear at once.} 36... Nc2 37.
