Should I practice openings of a famous player if I want to play like them? I have always liked the way Mikhail Tal played and I noticed on chessgames.com, that his most played openings are:

As White:

Sicilian (B46, B43, B82, B32, B40)
Ruy Lopez (C92, C95, C93, C96, C84)
Caro-Kann (B14, B17, B18, B12, B10)
French Defense (C07, C18, C09, C05, C16)
English (A15, A14, A13, A17, A16)


As Black:

Sicilian (B43, B40, B46, B22, B52 )
King's Indian (E94, E92, E98, E69, E62)
Queen's Pawn Game (E10, A46, E00, A40, A41)
English (A15, A14, A13, A10, A17)
Nimzo Indian (E48, E52, E53, E46, E56)
Modern Benoni (A56, A64, A61, A62, A65)


Mikhail Tal is regarded as the best attacking chess player of all time, but are the openings above indicative of his style? Are they openings that are indicative of an agressive, attacking player?

I know there is more to learning that openings, but basically my main question is if a certain player had a style, does playing their openings help you play with their style?
The openings are a good start; they give players like Tal the opportunities for combinatorial wizardry.  But it's a lot to ask of oneself, to play like Mikhail Tal.

They say that Tal played a lot of speculative sacrifices. That is, he felt the sacrifice was sound enough, but he didn't calculate it out to be sure.  Maybe.  Be advised, however, that the man didn't get to be World Champion by guessing.  He could calculate.

Unlike mere mortals, Tal's brain could cash the checks his fingers wrote.

If you want to play like him then develop your tactics specifically where unbalanced positions are concerned, look for opportunities, and don't be afraid to lose.  You'll have to be just as fierce, fearless, and skilled, relative to your peers.

NOTE - remember, what matters is that you win (or lose) the game well.  It does not matter if someone uses some computer to refute your moves after the fact.  The only refutation that matters is the one your opponent finds over the board.
