i wanted to ask this. I face opponents in long game tournaments OTB who are all like 2300+ online so I hope you understand this. It really becomes difficult if I go into the field with just half knowledge because I am just worse from the beginning. So I need something good so that I am not too passive and worse and go head to head with them and take the game to the endgame where my knowledge will decide my faith. If you guys want give me any suggestions about my choice, then you are welcome.
the Sveshnikov is perfectly fine. but know that you will need some understanding of the Najdorf as well since both defenses share the move e6. also a6 and b5 are wonderful ways for black to control his queenside in the Sicilian.
