Most brilliant move of all time?

Qg3 by Marshall was the first move to come to mind before I saw any posts and presto, there it was in post 2. 

There's a brilliant game by Alekhine but I can't remember the details. It might've been against Reti.

The most briliant move of all time is “to move on”!
