Blumenfeld Countergambit: Accepted (E10)

Jeremy Silman describes the gambit in an almost approving tone:

"THE BLUMENFELD GAMBIT: This old line (popularized by Alekhine's brilliant win with it over Tarrasch in 1922) still has supporters to this day, and might well be nearing a comeback. After 1.d4 Nf6 2.c4 e6 3.Nf3 c5 4.d5 b5 5.dxe6 fxe6 6.cxb5 d5 allows Black to take over the center, giving him serious compensation for the sacrificed pawn. Is this completely sound? I don't know, but many players don't like giving Black such a dynamic position and, due to this, moves like 5.e4!? and 5.Bg5!?, fighting for the initiative, are critical options.

For players who, as Black, want to gain a quick and easy-to-play initiative against a potentially unprepared opponent, the Blumenfeld Gambit is something well worth exploring."

My simple and far-fetched reason for being intrigued by the gambit is of course the James Bond Villian, Ernst Stavro Blofeld, as played by Charles Gray.

Did you say that chess is a game of Logic? 

The gambit has rather bad stats in the chess.com database (here).
