You don't need to go full into the opening, but rather know the basics of each opening.
All i know is that the Damiano's Defense is losing for Black (credit: @little_guinea_pig and @Leon_Likes_Chess) xDDDDD I find that my main problem is in my repertoire with the White pieces. For example, in teh tournament i crossed 1500, i got all my points with the Black pieces, but got 0 with White :/
Well, yeah, but you shouldn't even think of playing f6.
Then you need to choose your opening wisely. For example, I know you play the Evan's Gambit. That's fine, but what do you play against the Sicilian? How about Scandinavian?
I know you also play the Fried Liver. It's fun to play in blitz, but is easily countered.
My score with the Fried liver (otb) is actually pretty high, lol Against the Sicilian (with 2...d6) i know a lot of theory, since ive had to prepare for games in tournaments. Against the 2...Nc6 Sicilian, i dont know that much theory.......should i just play a rossolimo so i dont have to bother with the main lines ?
I have found this info but don't know how accurate it is.
