Hi Chessmates!

Novag Star Diamond and Mephisto Senator

SD passive book 70%, Normal book(tournament book) 20% Aktiv book 10%
MS Normal book 50% Tournament book 40% Aktiv book 10%
SD is more stronger with this setup.

Mephisto Milan PRO and Mephisto Senator

Both program used the same opening books:
Normal book 50% Tournament book 40% Aktiv book 10%

That is true, BT 2630 Milan PRO is better than Senator, because there is a program mistake in the Senator. Without this mistake, Senator would be the better chesscomputer.

SD: Unfortunately Star Diamond has also a mistake in his program, with EX ON in bt 2630 test 2112 ELO. With EX OFF => over 2200 ELO

Thanks!
Zsolt Jonas!
