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!
