White to play and win ( Alekhine-Nestor 1939)
1 Rc8! Rc8 2 Qe7 !! and the Queen cannot be taken due to promotion on c8.
Note that 1..Qd7 loses because of 2Qf8+!
And now an exercise ( difficult level) on passed pawns: White to play and win
Tal-Koblenz 1976

I think that the answer is: 1. f6!!
With the following:
1...gxf6; 2.g7, Rg2; 3.Rg1 and white wins (the promotion can be stoped only by giving up to black rook)
1...Bxf6; 2.Qxd6+ and after trading the queens (2... Qc7; 3.Qxc7+) white gains the material advantage by playing Bf4+ and Bxh2
1...Rxe2; 2. fxg7, Rxd2; 3.Bxd2 and the promotion cannot be stoped
1...fxg6; 2.fxe7, Rxe2; 3.Qxd6+, Qc7 (the only move that saves the mate),4. Qxc7+, Kxc7; 5. Bf4+, e5; 6. Bxe5+, Kb7; (6...Kc8 is met by
7.Rd8+ followed by c3 and thus white wins black's bishop), 7.Bxg7 with the ideea 8.c3 (to secure his own king,)it follows Rd8.
At least that's all I can see.
Do I get it right?
great analysis, very convincing !
1f6!! indeed wins.
two details:
1..fg6 2 fg7 Re2 3 Qd6+ Qc7, 4 Qd8 at first is strong as black can't take.
1..Re2 2fg7 Rd2 3Bd2!as you said 3..Qe2 last try 4 Kc1! curtains
