I see that Fritz does not understand this position.

g1 is a bad place for the white king.
I do not know if white can save the game but the move of movei(ke1)
seems to me more logical.

King at g1 when black's queen controls h3 and black has a bishop at d5 seems
very dangerous.

Fritz's score went down after Kg1 and it may be interesting to know if it keeps
Kg1 or find a better move after some hours of analysis.
