To save time, I stepped along as well, to see when the programs finally "got it" - ages. >Is there any program that resists to the temptation of Qxg7??? I would suggest only a program where the king safety consideration caused open files (typically g-file, also h/b/c/a maybe) to their castled king to be a sufficient no-no to prevent it. Unlikely IMO; there appears (to a comp) to be no other attractive move either, and the bishops raking the castled king position were there anyway (of course it is the combination of attacks on the castled position that doom white). Any programmer could easily adjust his program not to play Qxg7, as Moritz obviously knows, by adjustments along the lines just specified. Doing it without producing catastrophic weakening elsewhere is the hard (understatement...) bit.
