Sicilian Dragon (as white)

italian game
e4 as white
different openings as black, but usually e5

Dutch Defence against P - Q4 (US modern: Dutch defense against d4, I think). It's unbalanced and gives both sides a potentially exciting game.

Wikipedia: " in the past a number of top players, including Alexander Alekhine, Bent Larsen, Paul Morphy and Miguel Najdorf, have used it with success. Perhaps its high-water mark occurred in 1951, when both world champion Mikhail Botvinnik and his challenger, David Bronstein, played it in their World Championship match in 1951. Among the world's current top 10 players, its only consistent practitioner is Hikaru Nakamura."

I think Carlsen uses it when looking for a win as Black.

Normally...
as white, Queens Gambit Accepted.
as black, Latvian Gambit or the King's Indian Defense.

Traxler's counter attack

I don't know what's the favorite as I enjoy the variety, and it also depends on mood.

The mayhem that ensues in the Two Knights with Ng5 tends to be fun though, and from either side of the board.
