Queens Gambit final game Harmon vs Borgov

I just finished watching the Queens Gambit. I thoroughly enjoyed the story arc & drama of the Netflix series

I have to think this has been 'analyzed' already but a forum search didn't turn anything up, I hope this doesn't make me look too stupid but I don't see why Brogov resigned the game at the end of The Queens Gambit. (sorry, I am not yet allowed to post pics or I would post a screen cap of the final positions)

Harmon moves Rf8f2 to block Borgov's check with his queen (Qg2+Qe2)

Borgov again puts Harmon in check with his queen (Qg2e4+)

Harmon's King flees (Ke2d2)

No other Black pieces are pinning/attacking. Not even close. And Brogov resigns?

What am I missing?

It's because Borgov no longer has any safe checks, and Beth has a mating attack that cannot be stopped.  Here is the final position from the game after Beth slowly, dramatically placed her king on d2:

Thanks to the whole board being visible now I see it... because Brogov's queen was not only stuck but he could see Harmon could mate in 2

rf2f8, Qe8f7# (correct?)

So Borgov's queen is free to move, but - yes - he saw that mate was inevitable.  The best move from Borgov would be Qg6 to hold on a little bit.  But mate will occur within a few moves - although it is a fun exercise to work it out!

The game, both the real part, and the dramatic continuation, are analysed on YouTube ... Agadmator's channel

It was based on a real draw, played between Vasily Ivanchuk vs.Patrick Wolff, Biel Interzonal, 1993

Black's only hope in this game is to save a half point with a perpetual check, but he is out of checks!

WOW!
