In Aufsess 2001 (Germany) played CM6555 very, very good! Why any programs would play Kg3? This is (i think) a very good question for all program-authors! Here I have no answer. I think, that many programs in this position would mates and seen "first" 1.Kg3 Kf1 2.Kxf1, oh my bad english sorry, in german language I need say: "es droht weiterhin zunächst Matt plus Material- gewinn".
