was Tal the most aggressive chess player of all time?

I can't say I've studied a lot of chess players, but when you think of aggressive attacking style Tal's at the top of the list.  Are their others and what do you think of Tal?

I like to call Tal "Most Imaginative Player". He creates attacks, combinations and sacrifices from even equal middle game positions.

out of the word aggressive, i meant very tactical and sharp player?!''

Agressive isnt the correct word to use to describe Tal.  A better word would be imaginative.  

Janowski, Blackburne, frank Marshall, and Alekhine come to mind.

Bogolyubov and Yates were also go getters. I think Mischa (Tal) would have beat them all.

Here Rashid makes Tal look like Petrosian.

Both are the best attacking players in the history.(Many may not have the same opinion though.)

I would also include Morphy and Sultan Khan.

I think in terms of sheer tactics, Rashid was the best. Some of his sacrifices are out of this world. Though Tal is definitely the better overall player.
