Blitz & Rapid with white : Vienna Gambit / London System / Danish Gambit
Blitz & Rapid with black : King's Pawn Opening/French/Sicilian/Caro-Kann

Ever since I switched to the Alekhine as black, my win% as black has gone way up. I actually win more as black than I do as white now. Few people know the theory, so they don't play into the main lines and this allows black to equalize immediately. Nf6 in response to e4 is also the only one where black wins more than white in that other web site's database of 92 million games of e4 played.
It's a weird hypermodern opening that violates every principle that you learned, but if you learn the theory, you're going to win a lot of games.

According to the Sveshnikovs in their book A Chess Opening Repertoire for Blitz & Rapid, the answer is a repertoire that's forcing, both narrow and deep, and aggressive. In this context, they like the Alekhine for example.

I just use Queen's Gambit, French, Taimanov, Semi-Slav, Queen's Gambit Declined Exchange, and English Defense
