The openings are a good start; they give players like Tal the opportunities for combinatorial wizardry. But it's a lot to ask of ones selfoneself, to play like Mikhail Tal.
They Saysay 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.
