  al wazir: Why did white resign?

  beatgiant: <al wazir>
Maybe because there's no way to stop Black from playing ...Nh3 followed by ...Nxf2 with threats up the yin yang?

  HeMateMe: where's the 'Yin'?
Feb-21-21  RandomVisitor: 25.Qd3 was necessary. After that, it was survival of the fittest...

I'll buy that too.

I thought the idea of Bf6 was to allow Kg7 followed by Bxc4 and Nxf3, but couldn't figure out why Black didn't just move his king off the a2-g8 diagonal immediately.

Feb-21-21  Brenin: Daniel Yang was 11 years old at the time of this game. At least the resignation was a mature judgment: as <beatgiant> has pointed out, White has no reasonable defence against Nh3, Nxf2 and Bh4.
Feb-21-21  goodevans: <HeMateMe: where's the 'Yin'?>

I believe he was in the audience that day:

Feb-21-21  goodevans: <RandomVisitor: 25.Qd3 was necessary...>

The point being that the K will be much better off on e2 than on e1. With the K on e2 white's forces coordinate much better (e.g. his Rs can access the K-side).

White needs to consider whether f3 will become a target as becomes evident if the Q goes instead to d2: <25.Qd2 Qh5 26.Ke2 Ng5 27.Qd3 Nxf3 28.Qxf3? Bg4>.

After 25.Qd3 the same plan for black isn't quite quick enough: <25.Qd3 Qh5 26.Ke2 Ng5 27.Rh1> so f3 is safe.

Feb-21-21  RandomVisitor: <goodevans>Yes, white is able to fend off any black attack, and in turn take advantage of the exposed black king. The white queen is able to survive on the open d-file due to the Nd6-f7 trick. A longer run confirms the white advantage:
