why not promoting for a queen?

is there a reason the pawn wasnt promoted to a queen?

What if black's 2nd move was not Nb3? I see a few options that could still lead to draw.

nice way to stay out of a stalmate

very nice

wow!!!!!

173rd

in my opinion the puzzle wasn't very good i think there might be a problem if black plays this way: 1. n6c7,a1=N+ 2. kb2 but now instead of black playing Nb3 they might play instead kb4.

ah oo. taammaaaaa

why would black change to a knight and not a queen? makes no sense to me...
