It takes the current development version of Asymptote until depth 14 to see Bxg3 as best with a score of 135 centipawns. Score rises to 456 centipawns at depth 18, which was when I stopped.

What do you consider in your king safety evaluation?

King safety consider troppism, pawn shield and open file near king.

But that is not Minic issue, the attack is seen quite fast, but considered as a draw after many queen checks.
The needed rook move to continue the attack and win white queen is not found.
