most feared openings?

I hate facing the KGD and the Ruy Lopez.

I hate being on the Black side of a Four Knight's Game. From the Black side I also fear the Scotch and the King's Gambit. I have faced my fears by starting to answer 1. e4 with e5 almost exclusively. From the White side I won't play 1. f4 out of terror of the From Gambit. I tend to avoid open Sicilian and play Closed Sicilian instead. The general theme is that I tend to fear the openings favored by the rabidly aggressive attacking players. I prefer more positional lines. But I follow some grandmasters in seeking out the positional lines among classical king pawn openings.

I also play the g3 KID a lot, which is great since it avoids black kingside attacks if d5 is not played and often my opponents don't know what to do afterwards!

There aren't really any openings I'm afraid of (with my opening repertoire I avoid all the good gambits!) that I encounter, but the few that I often find boring are the czech benoni and the hippo.

Oh.  I forgot all about that nightmare.  The Schliemann has given me nightmares.  about a year back.  I've blocked it all out.

The k-k-kings gambit *shudder*.

Wait, is the Schliemann the one with F4? You guys are crazy man. That stuff is child's play.

Entirely agreed.

Everything in chess makes me nervous and I am afraid of every single opening with any color.

The Frankenstein-Dracula variation, the Bayonet Attack, the Halloween Gambit, the various Poisoned Pawn variations, the Dragon and the Pterodactyl.  Very scary!

I once played black against the Frankenstein-Dracula Variation in an over the board tournament and I knew none of the theory.  I used over an hour of my time to survive the initial attack and the following complications.  By midnight I had played on the edge, but then I unleashed an unsound knight sac.  I was two pieces down, but had three passed pawns on the kingside.  I managed to force the pawns up the board and came back, but I missed a win.  I managed to hold out for another 15 moves after winning a piece back and both of us queened.

I never understood why people don't like playing against the french. I love going against it! I especially like this cool line:

I find the tactics there very fun!

Also, I just enjoy playing against that pawn structure for some reason, and no light squared bishop to worry about!

no, its where black will plays f5 after Bb5, kinda like  answering the ruy lopez with kings gambit. I got rocked!

What is the Pterodactyl?

The Pterodactyl is a line of the Rat Defence popularized by Canadian IM Lawrence Day: 1.e4 g6 2.d4 Bg7 3.Nc3 c5 4.Nf3/dxc5 Qa5.

i often transpose to the pterodactyl through a hyperaccelerated dragon.

A line of the Modern Defence.

I am sure your opponents would love to find your weak spots. If it's not going to ruin it for you, I heard you most fear Anderssen Opening 

 I already know... you fear any opening I play, it is not the weapon that kills, it is whoever holds it.

Nothing bothers me, seen it all.

Mainly dislike boring openings I think that when you are not playing the game for a living why bore the pants off everyone.

Dont like the Slav, I just see too much of it.

Dislike playing against c4 and the Slav. I play both of them myself. I also hate when an opponent makes an unexpected move such as 1.e3 or 1.f3 or something like that. I know they should be at a disadvantage but I find it disconcerting.
