Mikhail Tal wasn't he the guy who would attack like nobody else and sac all his minor pieces and then queen and mate his opponent's full army with just 2 rooks?

Below is an example of Tal's genius for sacrificing major pieces to gain victory over an opponent with more material on the board. Here he sacrifices his Queen.
