{ A crucial game from the Open Dutch CC Ch. }
here my 2 cent.
[Event "24th DOCC"]
[Site "Leiden NED"]
[Date "2004.10.17"]
[Round "05"]
[White "Pro Deo"]
[Black "Chess Tiger"]
[Result "1-0"]
[ECO "B33"]
[Opening "Sicilian: Sveshnikov variation"]
1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e5 6.Ndb5 d6 7.Bg5 a6 8.Na3 b5
9.Bxf6 gxf6 10.Nd5 f5 11.Bd3 Be6 12.O-O Bxd5 {I don't like this move. What about
f4+Rg8 or Rc8+Rg8 and doing some attack too, but i guess both engines follow the
book and cannot disagree to the moves of jeroen. Mainly this whole game is
Jeroen beats Jeroen :-)) I looked this up, CT is of course in book here.}
13.exd5 Ne7
{from the beginning ProDeo had a very comfortable position.
no castling of black. double pawn. no pieces developed. I guess this is at least
+1 for white. Because of the Kings position b5 hangs. Hiarcs9 says +1,11 here !}
14.Qh5 {very aggressive. others would have played Nxb5 and eaten the material. I
guess this was played out of book ?! Yes. I looked at it. Book move.}
e4
15.Be2 Bg7 16.c3 {?! Rab1} O-O {If this is not book, it shows IMO the high
King-safety terms in CT, why not b4 or Qc8 or any other move on the queen side
taking advantage out of c3. But - i looked this up. CT IS in book here} 17.Nc2
Qc8 18.Ne3 {HERE ProDeo is out of book and computes first time} f4 {here CT is
IMO out of book and computes first time. Long time Qd7 ?! is preferred, i wonder
how fast the Leiden machine is. My version will not play f4. } 19.Qg5 {although
some moves were weird until here, white still has a good position. } fxe3
20.Qxe7 b4
21.fxe3 bxc3 22.Rac1 {DIAGRAM} Qe8 23.Qxe8 Rfxe8 24.bxc3 Bh6 {and ProDeo still
ahead} 25.Kf2 Re5
26.g4 Rxd5 27.Rfd1 Rxd1 28.Rxd1 Bf8 29.Rd4 {endgame position, still ProDeo
better} a5 30.Rxe4 Bg7 31.Rc4 Rb8
32.Rc6 Rb2 33.Rc8+ Bf8 34.a4 Ra2 35.Kf3 Rxa4 36.Bc4 h6 37.Rc7 Bg7 38.Bxf7+
{DIAGRAM} Kf8 39.Bd5 Be5 40.Rf7+ Ke8 41.Rh7 Ra3 42.Rxh6 Rxc3 43.g5 Rc5
44.Ke4 Rc1 45.Rh7 Rg1 46.Kf5 Rf1+ 47.Kg6 Rd1 48.e4 Rg1 49.h4 Kd8 50.Rf7 a4
51.h5 Rg2 52.h6 a3 53.Rf5 Bd4 54.e5 a2 55.h7 Rh2 56.Rf8+ Ke7
57.Rf7+ Kd8 58.Bxa2 Bxe5 59.Bd5 Ke8 60.Bc6+ 1-0
i don't see how Tiger could have turned this.
IMO the mistake was to let the BOOK ON . Why not play without book. CT would
have had better chances.
Its nonsense to play with a big book of writer JN against another big book of
author JN. The result in the end is nearly random, depending in which book
preparation line you land. Here it was -1 against Tiger. This makes no sense.
the engines should IMO play themselves, and not lose a game due to a stupid book
line.
they can do IMO tournaments for book writers seperate, there the book writers
can get their climax after such games :-)) but for a national championship i
would wish the programmers or programs would learn that books are made to HELP
and engine, not to decide games. the engine is the important thing, not the
book.
in this case the engine had almost no chance to stop the book line from running
into a lost position. programmers should not follow book lines BLINDLY. they
should let run the engine in the background and check if the book moves make
sense. if e.g. the book move is 0.30 weaker then the move the engine choses, i
would play out the engine move.
