Subject: Rybka EXE will bigger and bigger - why this?

Author: Eduard Nemeth

The first Rybka Beta EXE has about 2,5 MB.
Rybka Beta 12 EXE have now about 4 MB!

(I remember: Fritz 6 GUI-EXE has about 3 MB)

Why this? Much more knowledge now implementing?

I cannot see it. No EGTB at time and no endgame knowledge.

How big will be the final Rybka 1.2?

Testposition (the position is draw):

[D]8/8/2pK1k2/p4P2/P7/8/8/8 w - - 0 1

Analysis by Rybka 1.01 Beta 12 32-bit:

6.Kxc6 Kxf5 7.Kb5 Ke6 8.Kxa5 Kd7 9.Kb6 Kc8 10.Ka7 Kc7 11.Ka6 Kb8 12.Kb5 Ka7
  +-  (1.61)   Tiefe: 43   00:02:18  18953kN
6.Kxc6 Kxf5 7.Kb5 Ke6 8.Kxa5 Kd7 9.Kb6 Kc8 10.Ka7 Kc7 11.Ka6 Kb8 12.Kb5 Ka7

BTW: I need see a small engine with more knowledge and not a big engine with
little knowledge.
