that one opening you dislike

what opening makes you stressed out or gag every time you see your opponent play it?

for me it's the philidor because of how solid it is. you end up trading queens a lot if you dont want a closed position and if your not careful, you can find yourself with all your pieces tied down.

Lines where it seems white is going out of his way to play for a draw are annoying. There are some e4-e5 lines like this and e.g. Catalan lines that annoy me.

The alternative is a repertoire where I'm playing stuff like KID, which IMO is impractical if you're not willing to review your repertoire somewhat regularly to keep all the lines in your head.

idk

carocann

for me every thing which makes opponent win

Anti Fried Liver Defense. Doesn’t do anything and gives the opponent advantage. Even more is Andersen opening and Kadas opening because that basically gives up the center

Accelerated London.  Boring. 

Stonewall but maybe because I just don't know how to play against it

Englund can be tricky and the french defense

English opening sucks

i hate when ppl see my rating and then go for the scholars mate, but at the same time i kinda like it since i can get an easy advantage out of the opening

The French because I can never remember how to play it properly! Also: all Sicilians!!
