[November 07, 2018] Updated Opening Line by Bojan Vučković:
Blumenfeld Countergambit

[Line 195 : 1. d4 Nf6 2. c4 e6 3. Nf3 without 3… b6, 3… d5, 3… Bb4+]

Line 195 covers the alternatives to mainstream openings: 3… d5 (Lines 229-285)3… b6 (Lines 202-228) and 3… Bb4+ (Lines 196-201).

The most popular among them is the Blumenfeld Countergambit, arising after 3… c5 4. d5 b5. White usually accepts the challenge and takes the pawn with 5. dxe6 fxe6 6. cxb5. Move 6… d5 is the most critical option here, though 6… a6 also seems fine. After 6… d5 7. g3 a6 8. bxa6 Be7, followed by O-O and Nc6, Black has sufficient compensation for the sacrificed pawn. Players of White sometimes also opt for 7. e3, 7. Bf4 or 7. Nc3, with the idea e2-e4, but the evaluation stays the same – chances are roughly equal.

Move 5. Bg5 is an interesting possibility for White. Black should continue with 5… exd5 6. cxd5 h6, where he is fine after 7. Bxf6 Qxf6 8. Qc2 Be7.
