In the game, Black forced the draw with 68.... Rh1+ and a repetition.
What happens if 68... Kd1
Hint:
68... Kd1 Threatens both ...Rh1+ winning the Be1, and ...e3-e2#.
So White should either counterattack with Ra4, or save the Be1 by moving it somewhere safe.
Counterattack...?:
Counterattacking Black's B with 69.Ra4? loses in a study-like way: 69...Rh1+ 70.Kg2 Rg1+ [only move] 71.Kh2 Kxe1 [only move] 72. Rxd4 Rg8 [only move] (72... Rg7? 73. f5 [only move] =) 73. Rxe4+ Kf2 and the mate threat wins the Re4: 74. Kh3 Kf3 -+.
Saving the attacked piece? Not like this...
69.Bb4? Rf2+ 70.Kg1 Rb2+ wins the B.
69.Bc3? Rf2+ [only move] 70.Kg1 Ra2+ wins the exchange.
Saving the Be1 for real...
69.Bg3! Rd2 70.f5 (70. Rb3? e3 -+) 70... e3 71.Kg1 e2+ 72.Kh1 only move.
And now Black has his last chance to perpetrate some endgame evil:

[from the diagram]
72...Be5!? 73.Bf2 e1=Q+ 74.Bxe1 Kxe1:
75.Re3+ forcing the exchange of Rs with an easy draw, right...? 75... Kf2! wrong! 76.Rxe5 Rd4 -+ it's mate!
75.Rf3! Rh2+ 76.Kg1 Ke2 77.Ra3 Rh5 is a theoretical draw, but it's 50 moves of indigestion for the defender.
Conclusion:
68... Kd1 creates the possibility of some beautiful, study-like wins, but with best play White can draw by going into the defending side of a theoretically drawn R+B v R ending.
