what's your most hated opening to play against?

i don't necessarily have a hated opening but more of an annoying one which is tricky due to theory. in this case it used to be the sicillian but nowadays i am kinda getting a little more comfortable and less annoyed playing against it

Englund Gambit

The scotch game and the Sicilian. The scotch gambit has many f=different tricks and sacrifices so it is difficult to play against. The sicilian because black has so many options like the Nadjorf and the Dragon which is difficult for me to play against.

Italian Game. (e4-Nf3-Bc4)

Slav Defense, I mostly suck against it!

Definitely the Queen's pawn opening because I'm always used to the King's pawn opening

@pointlesswindows said in #4:

Learn systems like antisicilian and your hated openings become favourite.

What if antisicilians are your most hated opening? Particularly the really passive / closed lines that don't break in the centre at all, I wouldn't mind if I was facing a lot of Alapins or Rossolimos or whatever. I mean, the Open Sicilian has a scary reputation for being super-theoretical but it's not that hard to find lines that are "ideas based", features fairly similar setups against a lot of variations, and where you aren't just going to get checkmated if you don't know thirty moves of theory, so why not just play into it, get an interesting, dynamic, unbalanced position and play some fun chess.

Although I've ended up doing quite well against the King's Gambit, I was lost in almost every game.

1.e4 because you can't play the Schlechter Slav against it

Probably the London. Oughta start learning counter measures.
