After  move 40 in Game 8 of WC 1960

Botvinnik put his move 41 in an envelope. When it was opened again and the inserted move was executed Tal directly resigned the game.

Which move had been played? )Please think first and then give it a try)

After 1. Nf7+ Kh7 2. d6!(instead of 2. b7?) one of the passers would walk through:

Oops, and 4.d6 as in the puzzle loses to 4...Ke8
4.h5 wins though.
