Keres's One Move Knockout (Keres vs Spassky, Gothenburg, 1955)
Paul Keres (1916-1975) doesn't need an introduction in the chess world. When I was growing up in Estonia in the 90s he was still known to everybody (partly because he was on the 5 crown note shown below).
I've been recently reading "Paul Keres, The Quest for Perfection", a game collection authored by Keres & John Nunn. I thought I'd give you a taste by presenting a game where Keres plays the Queen's Indian Colle-Zukertort style against Spassky in the Gothenburg Interzonal tournament in 1955 and wins with with a bolt out of the blue. The highly instructive annotations are from the above book (I hope that they inspire you to read it).
