Some moves make an impression on you forever, and this is certainly one of them.

Stockfish was a piece for a pawn up and completely winning against Leela Zero’s baby sister: Leela CPU. Many moves would finish off the job, but none so powerfully as Stockfish’s…
45.Bc3!!

45…Rxd3
i) 45…Qxc3 46.Qd8+
ii) 45…Bxc3 46.Qd8+ Qg8 47.Rf8 wins
46.Rf8+ Qg8 47.Bxg7+

The right move order: White exchanges off all of Black’s pieces leaving the black queenside pawns helpless against the attack of White’s bishop!
47…Kxg7 48.Rxg8+ Kxg8 49.Bxd3 b4 50.axb4
and Stockfish soon won!
