How to learn the Sicilian defense?

Hi. I'm going to learn how to play the Sicilian defense. I have never played it before and I don't know where to start, which version is the easiest to learn? Which is the best / most popular version? Which versions is unnecessary to learn? I play a lot against it as white, but I never play it as black. I have read that it is a good opening for my style of play.

Thanks in advance for any answers.

I always play sicilian defense you can practice with me :)

Nbd5? I think that looks weird. Is Nb3 the main line? I want to play the sicilian as black, was that for white?

Nope. What Harish showed is the mainline of the Sveshnikov . The Sveshnikov is a sicilian where black accepts structural weaknesses for good counterplay. White plays Nb3 is the Najdorf because black had played a6 first to take away the b5 square. Note the difference. Check the link I posted above, it explains all these.

Ok. now I understand

You never really learn the Sicilian. It teaches you.

Yes when you play it, you'll always learn something new in every game, and if you play strong master and frightened beforehand, this happens... https://www.chess.com/livechess/game?id=1527843574

I have won all my sicilian games so far. But that's because all my opponents decided that they should give away pieces for free and then resign.

I feel so confused and unconfident when I play sicilian. I have played 1000+ games with 1.e5 so that is how my brain works....
