Your position above.
White is no danger of losing if he plays the most natural move 13.Kxf2, and Black has to find a unique drawing (by perpetual) sequence to stay alive: 13.Kxf2 Qh4+ 14.Kf1 Bh5!
Everything else loses for Black.
And (one more time!) 5.Nxf7 is wrong.
If White plays KF1, he has drawing chances you showed me in the other thread on this. KxF2 is suicide
So, it's rather sad that after two long threads you are still claiming nonsense.
The following "game" has been played a lot of times after 6.Kxf2 by various opponents, and leaves no room for Black improvements.
