Welp, I would think you should try a variety of openings. I'm not a Caro-Kann person, so I can't really speak for that.
So does that mean, I should try 1.e5 or 1.c5 as well? Because I don’t think Sicilian would suit my positional play style. Maybe e5?
I’m a young player. Against 1.e4, I only play the Caro Kann, as I don’t want to get such sharp positions like in the Sicilian. When OTB tournaments are back, should I keep playing the Caro Kann only, if I want to improve to 2500 rating? Or should I also play 1.e5 to make it harder for strong players to prepare against me?
In short words, is only playing the Caro Kann enough if I’m playing against masters?
