C65: Ruy Lopez: Berlin Defence (3...Nf6), unusual lines and 4 0-0 Bc5
Very nice game! This game was played in the style of the great Alekhine
himself. What is also interesting to note is that Chessmaster 10th was
playing in its own interface, using its own opening book, and also assisted by
use of its own endgame tablebases, even if it never reached an endgame where
they would have been of use. Rybka on the other hand was using the polyglot 1.
3 adapter to play within the Chessmaster interface with no opening book and no
endgame support. This game was played on a PIV 2.8 Ghz system with 1.25 Gig of
Ram. Time control was 40 moves / 2hours

After transposing into a Ruy Lopez Opening (Berlin), black
plays a novelty on its 6th move 6. ... Bd4! I have searched my databases and
the online database at Chessbase but could not find black's 6th move anywhere.
7. c3
Consolidates b4 and d4.

We reach a position where black has a very active position, meaning black has
two the bishops on active diagonals, and open files for its rooks to use, at
the price of taking damage to its pawn structure. White of course as a result
has the better pawn structure, however is behind in development.

Black's has an enterprising idea of g5 followed by f5.

[D] r2qr1k1/pbp4p/1bpn4/4N1p1/5p2/2PP1QB1/PP1N1PPP/R4RK1 w - - 0 17
You cannot say that black has not been consistent with the plan started by its
14th move. Hard to believe that this is a software engine playing so much like
a human grandmaster would.
17. Bxf4 gxf4
18. Qxf4
Black wins a piece at the cost of weakening the pawn wall around its king.

22. Re3 Bd5
I found this move very interesting, I would have preferred the more than likely
weaker c4, if for no
other reason than activating the black squared bishop.
23. c4
[D] 4rqk1/p1p1r2p/1b1n4/2pbN3/Q1P5/3PRN2/PP3PPP/5RK1 b - - 0 23
Rybka felt that this move was weak for white and preferred 23. Rfe1 better. I
liked the
move as I felt it shut black's black squared bishop out of play.

Black sacs the rook to gain a very strong positional bind on the white camp.
32. gxf3 Bc6

If white played 33. Qa6, then black has 33. ... Bd7 with the idea of Bh3 to
follow.
