Default Can Fritz8 beat GetClub Master Level.

What do Taylor Kingston Say.


Sanny, I already registered Fritz8 with your "new improved" program,
and have pitted the two programs against each other in several games
at various levels, including "master" if I recall correctly. It was no
contest. Fritz8 slaughtered your program. So the match you ask for has
already been played, just check your records.


That was I think 2-3 days back. After that the Game was improved and
now it has outplay many good players.


Nonsense. Yesterday afternoon I started a game between your program
and Fritz8. GetClub moved so slowly I could not finish the game until
this morning, but essentially the game was over by the 7th move, when
GetClub threw away a piece for almost nothing, and then played so
idiotically that it lost any chance for compensation. Here is the
game:

White: GetClub
Black: Fritz 8

note: time used, in minutes and seconds, given after each move:

1.Nf3 10:00 d5 :00 2.d4 6:10 Nf6 :00 3.Bg5 18:39

Notice the long think. Sanny's program repeatedly overstepped the
self-announced time limit of 5-10 minutes per move.

3...Ne4 0:00 4.Qd3? 6:03 Nxg5 0:19 5.Nxg5 8:40 e5 0:00 6.h4 13:31 h6
0:23 7.Nxf7?? 13:32 Kxf7 0:04

Basically, the game is already decided. White might have had some
slight chance if he'd followed up the knight sac with 8.dxe5, but
Sanny's program proceeds from bad to worse.

8.Nc3? 13:52 e4 0:10 9.Qb5? 5:58 c6 0:00 10.Qb3 9:47 Qb6 0:00

Good, straightforward chess technique. When you're ahead in
material, seek to exchange queens. White must oblige or lose the d-
pawn.

11.Qxb6 6:27 axb6 0:02 12.Nd1 14:05

A ludicrous spectacle. Not only is White a piece down, but he's lost
control of the center and does not have a single piece developed.

12...c5 0:17 13.Ne3 10:32 cxd4 0:10 14.Nxd5 14:59 Be6 0:00 15.c4 13:07
Bd6 0:00 16.g4? 16:39 b5 0:05 17.e3 7:18 bxc4 0:00 18.Bxc4 6:02 Rc8
0:00 19.b3?? 9:49 b5 0:00

Most human players would probably have gone for more simplification,
but Fritz8 has enough calculating ability, even at very quick time
limits, to handle this more complicated line.

20.Nb6 11:27 bxc4 0:00 21.Nxa8 9:15 dxe3 0:00 22.O-O 11:26 Nd7 0:04
23.fxe3+ 23:15 Ke7 0:00 24.Rf2 9:11 Rxa8 0:04 25.g5 7:38 cxb3 0:02
26.a4 8:23 Bg3 0:00 27.Rd2 7:51 Bxh4 0:04 28.gxh6 7:45 Ne5 0:00

Most human players again would probably just chop wood, but Fritz is
weaving a mating net.

29.Kh1 13:16 Nf3 0:03 30.Re2 14:52 Rh8 0:00 31.hxg7 16:23 Rh6 0:04
32.Kg2 8:30

At this point Fritz announced mate in at most 8.

32...Rg6+ 0:00 33.Kh1 15:56 Bf6 0:06

Here I shut down for the night, and restarted the game this morning,
hence the "0:00" time for White's next move

34.g8=R 0:00

Seems odd to promote to a rook, but that's what Sanny's program did.
Doesn't matter anyway. The way Fritz now completely ignores the newly
promoted piece is amusing.

34...Rh6+ 0:00 35.Kg2 6:18 Rh2+ 0:00 36.Kf1 6:23 Bc4 0:00 37.Rae1 9:42
Bh4 0:00 38.Rg7+ 9:41 Kf8 0:00

And here Sanny's program resigned; after the spite check 39.Rf7+ Kxf7
it's mate next move.

I trust this satisfies Sanny's curiosity about the relative merits
of his program versus Fritz8, and puts paid to the notion that his
program is "improving." I will waste no more time on this issue.
