Mine is the King's Gambit!!
Your Favorite Opening?
As White, my favorite opening is the Ruy Lopez
As Black, my favorite response to 1. e4 is 1...e5.
I play 1...Nf6 against 1. d4. I usually follow up with 2...e6. My favorite opening against 1. d4 is the Queen's Indian Defense.
I treat 1. c4 and 1. Nf3 as if they're normal 1. d4 openings. (They easily transpose.) If my opponent plays strange moves, I'll simply develop and control the center.

Oh... I forgot To tell my favorite as black it is...
If e4 I play..
Sicilian defense, Dragon varaition.

Recently at the World Cup Giri had a very nice win versus Leko with the Catalan and at the Sinquefield Cup Nakamura had an exciting win versus So with the KID.
My favourite is the KIA ( King's Indian Attack ) as white.
As black, I play the French Defense and Sicilian.
I love play as a defender.

What if they don't transpose to 1. d4 OR play strange moves? Like if they play the usual English/Reti/KIA setups?
