Nice analysis by Rybka Beta 13 with EGTB now! 1.a4 is the once winning move.

Only like Beta 12 (German: keine exakte Mattangabe wie "Mate in X").

No Endgame Knowledge at time (like K+B+N vs. K without EGTB).

But ok, Rybka Beta 13 was new only the implementing from EGTB (German: EGTB
Suche).

Thanks Vasik!

Question to Vasik: When will Rybka have the underpromission (Unterwandlung?),
see Testposition ?
