It might (or might not) help to know what you play as black against 1.d4. I knew an NM who played the Dutch, as white he eventually switched from 1.e4 to 1.f4. A Nimzo-Indian player might check out 1.b3 (or 1.Nf3 and 2.b3). Lev Alburt used to play the Trompowsky.
But most Alekhine players do stick with "e4 or Queen's Gambit"....
Im looking for an offbeat opening as white to get out of the most played e4 or Queen's Gambit, any suggestion?
Thanks
