Well I have finally finished the Tournament with Rybka, Fritz 9, Fruit 2.2.1 and
Shredder. Rybka came out way on top with Fritz in second place and Shredder and
Fruit 2.2.1 tied for 3rd and 4th. I wanted to post the diagrams as EPD's but it
is really late and I have already spent almost 2 weeks on this adventure and I
it 4am and I am dead tired. I have instead just moved some of my analysis into
the .pgn file (please forgive any errors in analysis) If someone would like
they can post the critical diagrams (thanks in advance). Since Fritz 9 was
using its own book that is especially tuned for its style of play, I think the
other programs were a little handicapped because of that. Rybka though seems to
be "book immune". It can win with ANY book. Also it seems that Rybka was also
handicapped with poor time management at this fast control. Almost every game
Rybka had 2 or 3 times more time than its opponent ... still it plays extremely
strong. My final impressions are that Rybka has found a weakness in all other
engines and that is that it can identify which are the critical lines and search
those critical lines extremely deeply. As I have mentioned before, it is as if
a Super GM is guiding which lines it should probe. This dramatically increases
the strength and is especially lethal in the opening and the middle game when a
lot of pieces are on the board, and a lot of things can go wrong. Rybka has a
weapon that other engines cannot defend against as of yet ... and that is the
evaluation of pawns that are pushed down the board in the middle game. The many
critical lines that Rybka correctely outcalculates the other engines usually has
pushed pawns involved. Yet this tremendously strong beast of an engine has some
glaring weaknesses. It managed to lose a Rook vs Bishop and played some
endgames that even a 1400 elo player could do better. It still is very naive
about obviously drawn positions and will rush headlong in such positions even if
it easily winning. Don't get me wrong, it can play some incredibly strong
endgames against the strongest engines out there, but it has gaps that are
really glaring. I will say that those gaps seem very easy to fix, and with a
fantastic source such as Fruit 2.2.1, it should be very easy to easily improve
on that. What would be great is if Rybka can manage to outdo the other engines
in endgame play as well. Some endings need guidance (similar to the guidance
needed to evaluate pawn pushes) to look at the critical lines. It is hard to
imagine something stronger than today's Rybka especially with such lopsided
victories. But add a good book for Rybka that can take advantage of its
strengths plus a good endgame knowledge strategy and some better time management
algorithims .... and you have a real MONSTER !!!

Rybka plays this passed pawn in the middle game is truly instructive. White
usually plays Bg2 which gives white many more options. –0. 72/10 13 19...cxb3

this doesn't win the game for white it shows that Fritz has a great
understanding of such endings. It gives up the pawn so that it can activate its
King via f4 - g5 etc... Fritz seems to know it is a draw but plays the most
active way, Rybka on the other hand does not understand this position and does
not react to try to control the g file with its rook. 0.01/155 81...gxf5

7 55.c6? (a5)This just looks wrong. a5 seems much stronger. Why give up a pawn
for nothing? It seems that Rybka has hit the panic button a bit too early and
thinks that it will need the bishop to control the black center pawns. The white
King can still move back to the pawns and if needed. I think here that Rybka
does not quite understand how drawishy opposite bishops are in the ending.

evaluates that doubling of the pawns in this position is worth the initiative

beat hardware monsters such as Hydra. They just will not calculate the
consequences of this move because it seems weak. With this capture Rybka has
already eyed a couple of pawn moves which will give it a strong initiative. This
type of pawn play is a weapon that all other engines just don't seem to have any
protection against. –0.73/11 7 22.Bc3 –0.21/12 9 22...b4! (Rc4) –1.05/12 7

ending he sure made things a lot easier for white. Now only white has winning
chances. Black should keep queens on the board and not invite an exchange of
queens that gives only white any chances. 0.00/12 4 38.Qd4+ (Qd5) 0.02/15 13

protect the h pawn with a d runner is futile. Black's best chance (if he has
one) is to play Kf5 and somehow hope that after snatching the d pawn he can hold
the fort by trying to get his King to get the opposition. 1.37/1911 41.d5

47.Kg1 White looks very solid here with two connected passed pawns. You could
even say white is winning (at least Shredder thinks so). Well Rybka has other
plans and shows some really impressive middle game play with its by now
legendary forceful pawn play. 1.07/ 14 6 47...Qd4 0.13/11 2 48.Qc4 0.97/14 11

52.b3 1.01/13 4 52...Kh6 (Kf6) 0.24/12 4 53.h4 1.11/14 4 53...Bd8! Here Rybka
sees the passers are on the a and b file are too slow and moves the bishop from
defense to attack. I think no engine again will play this move because the other
engines will not calculate the pawn pushes that Rybka is looking at. 0.00/12 8

68...Qe5 Another great game from Rybka. Obviously Shredder could have defended
much better, but the strength in Rybka is that it sees moves that other engines
are not even calculating. This makes them react too slowly to danger. –13.02/11

ending is impressively won by Rybka against arguably the strongest endgame
engine in such open positions. When I was watching this game I thought for sure
white would lose this game especially after it seemed that the white rook was
almost trapped on the 8th file. But I had no idea that Rybka planned to sac that
rook and overwhelm black's queenside with it's King. –0.66/16 11 35.Kf2 (g3)

has completely outplayed Fruit and is probably in a position that most programs
would give up by now. This is a position that even an 500 elo player would win
against Kasparov. Simply Queen the pawn with check and then it is a simple mop
up of the pawns and a simple Rook mate. 4.07/13 3 62.Ra4?? WHAT IN THE WORLD IS
THIS ????!!!!????!!!????? Rybka goes for a Queen and Rook with 2 pawns ending
instead a simple Rook win. Although this might be a win for white I could not
get any engine to find a win. It might be a draw even with best play by white.

0 29.Rb6 This is the last book move by Fritz in its own book. Looking at the
Queenside and seeing the future passed pawn looks like it could be very
dangerous against Rybka. Obviously Fritz has had good success with this, but I
don't think this book was made when Rybka was around. I expect many changes in
this book to avoid such positions. 0.00/13 17 29...Nd7 0.00/16 14 30.Rbe6

looks like the last book move by Fritz from its own book. This just looks like
the pawn push is way too premature. Rybka takes advantage of this weakening move
and starts a strong initiative. 0.97/12 23 21.Qg3 0.54/11 10 21...Rc8 (c6)

4.16/14 5 64.Rxa7 5.87/11 1 64...Kf8 4.17/16 4 65.Kc5 Here white has a
completely winning position. He is a bishop up and he still has a pawn that can
Queen. The easiest way to win this position is to ofcourse flush out the King
and try to keep him away from h8. Then you use strength of the extra bishop to
take the black pawn. The rest is just moving your King in front and Queening the
pawn. This I guess is called endgame knowledge. Here is an example of how to win
this ending. 5.88/13 3 [65.Bf7 Rd6 66.Kc5 Rf6 67.Bg6 Rf1 68.Ra8+ Ke7 69.Re8+ Kd7

dangerous. Almost immediately after Qf5? Rybka realized it was a blunder and its
evaluation jumped to +3.20 It realized that the critical line is that if the
Queens are forced to be exchanged the black Bishop will be in trouble and that
even though black has more pawns the Rook will completely dominate the pawns. In

–0.29/16 9 52...Bxa5 -4.13/16 3 53.Kf2 (Kf3) -3.30/14 15 53...Kc4? Another
position where Rybka could use some endgame knowledge. Bb6+ not allowing the
white king to hide on a white square on h1 is the best plan. If the white King
cannot protect the h1 square this ending is an easy win for black, but if he can
make it to h1 then it is a draw. -4.30/176 [53...Bb6+ 54.Kf3 Bg1] 54.Ke3? I
guess Fritz doesn't understand this position either. Obviously the best plan is
to rush to g1 and then he should be able to draw. -4.63/13 6 54...Bb6+ (Kc3)
-4.33/13 6 55.Kf3 (Ke4) -3.56/14 6 55...Kd3? Here black has to watch out for the
possibility of g3 or g4 which will allow white find a path to h1 so he cannot
allow that. So Bc7 was necessary. -5.06/ 16 6 56.g4!! Fritz doesn't waste the
opportunity. It is now a draw. -5.96/13 6 56...Bd8 -5.06/16 7 57.g5 (Kf2)
