If 33.Kg1 Qc8 34.Qe3 Qf8 35.Qe5 Qc8 is headed for a draw,

33...Qc8 34.Kg3

34.Kh2 is more adventuresome, but it's still an equal game.
If 34.Kh2!? a6 35.Rd3 Qd8 36.Qf6 Qf8 37.Kg1 then:

If 37...Qb8 38.Qe7 then:

38...Qc8 39.Qe4 b5 40.Qe3 Qc2 41.Kh2 Qc8 42.Qe5 leads nowhere.

38.Rd3 Qe8?!

With the f-pawn advancing, Black needs to whip up counterplay to keep the game in balance.
If 38...b5! 39.Qe5 then:

If 39...a6 40.Kh2 Qf8 41.f5 Qd8 42.f6 Qb8 43.Kg1 then:

White is playing for a win.
40.f5 Qc8 41.Qe5 a6 42.Rc3 Qf8 43.Rc6 gives White a stronge advantage, but not quite a sure victory.

40...Qf8?!

Black's position is now difficult, but after 40...Qc8 41.Rc3 Qf8 42.Rc6 Qd8 43.Qf6 Qf8 44.f5 she can put up a more stubborn defense.

41.f5!
