I don't believe it is higher but I used to.
In unrelated news, unfortunately I forgot about the positions. I think I saw three of these Kf2 moves.
To answer the question, I have Rybka 2.3.2 or so and I understood that it's OK for not very good players like me. But I've also seen in one of the opening books "Fritz (11) prefers Kf2 but I don't think any human would play it at the table" or WTTE.
Sometimes computers make crazy king moves like Kf2 (in the opening) for no apparent reason. Has anyone else seen the same behaviour? Has anyone figured out what the reason is for them? I guess it's that sometimes when white made f2-f3 then the king can be safe on f2 and the KR can stay on the h file?
