Hello, good morning to all,
last match from quarter-final phase is a Lang family affair: smart vs fast, Mephisto Berlin vs Millenium Chess Genius Pro.
In the first game as White, the Berlin can only play two moves out of its openings library before being forced to computing by the CGP (for information, I let the default setting, thus book 2 which is the big modern "HIARCS" book).
Surprisingly enough, I was able to instantly spot a positional mistake from the Berlin, on move #39. I am not used to positional mistakes performed by this Lang program (a Vancouver in disguise), and further more not used to be able to see these by myself. Maybe I am not so bad at chess?

ok, dream off

. Anyway, the rest of the game provides later evidence this positional error was a bad mistake: the involved Knight won't anymore be any useful to the Berlin, compelled to resignation.
The revenge game is balanced, with a center kept closed for a while; once some pieces exchanges are performed the position is slightly in favor of the CGP. Thus, the Berlin plays for a draw and achieves a 3-fold repetition.
The outcome is 1.5 to 0.5 in favor of the fast Chess Genius Pro.
