What is your opening repertoire?

I'm usually an all-rounder, because it's good to study all lines that your opponent might do. My favorites are e4 and d4 though. Some of my favorite opening lines:

Sicilian Najdorf

Sicilian Dragon

Nimzo-Indian(Huebner Variation)

King's Indian

Ruy Lopez

Oh yes, and I love playing the Maroczy Bind as White. It's so simple, just set up your position with usual moves like Be3, Be2, Qd2, b3, Rc1, 0-0, and you just have a great game. Black pretty much has no counterplay except pawn breaks with b7-b5, f7-f5, and d7-d5, all aimed at targeting White's pawns at c4 and e4 which put a bind over Black's position. Note: Endgames also favor White also.

I only play one white opening: The Danish Gambit.Against the half-open defenses to 1.e4,I play gambits  whenever possible,such as vs the French and Sicilian,I use  the Panov-Botvinnik vs the Caro.Against modern/hyper-modern defenses I just play by principle.As black, I answer 1.e4 with 1.e5 and 1.d4 with 1.d5;the defenses I use the most are the Petroff and Queens Gambit accepted. I accept all gambits as black.Against junk openings I just develope and look for a chance to kick in the house-of-cards.

Solid repertoire: Queens Gambit and Trompovsky with white

                         E5 and Marshall Gambit with Black

you call the marshall solid? ;)

Yeah at least you will have a draw in well played ending without queens ;)

lol yeah guess your right

I like to mix it up. I do prefer playing 1 e4 as white, htough I have been known to play the Grob 1 g4?! or the St George Attack 1 b4?!. I also use 1 N-f3 an dthen follow with various thibgs depending on opponent's replies.

Playing odd side subvariations is my forte to get opening freaks out of their depth quickly.

As black, I like the Pirc, sometimes a finchetto variation, and various lines including double king pawn games (familiar with a lot of lines in many of them as I played them when I was younger).

Here is a nice game in the marshall :

Hope you enjoy ;)

To answer the OP, these are my most common openings:

Black: CK, QGD, Reversed Sicilian.

White: c3 Sicilian, Spanish, Exchange French, Exchange CK. (I like IQP positions)

I used to have a very small repertoire but now my most common openings:

White: KIA, Nimzo-Larsen Attack, King's Gambit, Scotch Gambit, Smith-Morra Gambit against most opponents, against higher rated I go to london system or Trompowsky/Pseudo Trompowsky.

Black: Used to play only sniper, now I play: KID, Modern, Slav vs d4 and vs e4 Scandinavian/Icelandic Gambit, Latvian Gambit, Petroff Defence.

As white - e4 - King's gambit, Grand Prix, Fantasy Caro, Winawaer french.

As black. If e4 - French. If d4 - e6. If they follow with c4, I play Nf6, if they then follow with Nf3, modern benoni, if they follow with Nc6, nimzo indian. If they don't play c4 after d4 I play dutch defense.

As white:

As black:

I drill myself with traps mostly, as they are most beneficial when playing against 1200-1500 ratings

I see you've had better results with you first choice, the King's Gambit (52% wins, 44% losses), than with 1 e4 in general (48% wins, 48% losses).

That surprises me because your tactics rating isn't high.  With your strong understanding of the opening, I bet your rating would rise dramatically if you worked on tactics!

I've only played the King's Gambit twice and only in the past year - after decades of rated chess play - and was pleased to win both games.  It's a change of pace opening for me, but I'm sure to use it more!

Am I the only one who hasn't gotten a complete opening repertoire?

I really play openings randomly. I can't say I haven't studied the main lines and the variations of my openings honestly; I've just watched some games of GMs I like (Bobby, Kasparov) and try to see what they do with certain openings. For example, I've learned some basic stuff about the Ruy Lopez thanks to Bobby Fischer's games, but I don't always do the Knight maneuvre which is part of it. I just start with the Ruy Lopez and then randomly go with something else I don't even know.

The only "opening" I've studied a little is the Queen Pawn Accepted and Declined, I've bought a book and saw some tipical black defenses against it. But I don't really use the variations I've read a lot anyway, at my level most of the players don't really know any opening so they'll just go with the basic opening principles like me.

I've had some troubles in my openings for quite some time, and I thought I should have studied them multiple times. But then I found out that what made me lose wasn't the openings but very basic tactics, which I'm now training 30 minutes a day. Just after 2-3 days of tactics I don't do the errors I'd do before, and my rating has going up recently (from 1100 here on chess.com to 1350 in 1 week, 15|10).

So I have to say that I'm quite happy. Now my goal is 1600 here on 15|10. I'll train tactics 1 hour a day, and when I reach that rating, I'll get to study some openings.

I have an opening repertoire for 10 minutes games. As White, Scotch, Petroff 3. d4, Carokann 3. Nc3, French 3. Nc3, etc. As black, Sicilian Classical and Gruenfeld.

I usually play C4 (English opening) or E4 (king's pawn opening). I only took an interest to chess over the last few months so I'm by no means good.   

With white I play stonewall. with black I have learnt a couple of defences but mostly just play off instinct. I can defend against Danish and the early queen, but other than that I just try to play from instinct.
