Rare DDG Moves
Most openings have a number of reflexive moves: some pieces are always
played on the same squares. Here a few typical moves and assumptions
of the DDG are questioned, by presenting rarely played but interesting
alternatives. These moves deserve more analysis, which should result
as new ideas for the DDG.
Assumption 1: if exf3, White plays Nxf3
Idea: Qxf3 when d4 is supported by Be3.
Example: 3... dxe4 4. Nc3 Nf6 5. Be3 Be7 6. f3 exf3 7. Qxf3 O-O
8. O-O-O c5 9. d5 exd5 10. cxd5?? (10. Nxd5) Bg4, 0-1 in 14, Heikkinen
- Evans, corr. 1997.
However, 5. f3 exf3 6. Qxf3?! Qxd4 looks too bold.
Idea: gxf3 might work especially if White has castled
queenside. Above all, the half-open g-file provides great attacking
chances against Black's king.
Example: 3... dxe4 4. Nc3 Nf6 5. f3 Nc6 6. Be3 Bb4 7. Qb3 O-O 8.
O-O-O exf3 9. gxf3 b6 10. d5 exd5 11. Nxd5 Bd6 12. Bg5, draw in 19,
Ortwin Pätzold - Mark Smits, IECG, 1997.
Assumption 2: if exd5, White plays cxd5
Idea: Nxd5. Of course, Black should avoid exchanging knights.
Example: 3... dxe4 4. Nc3 f5 5. f3 c5 6. d5 exd5 7. Nxd5 Bd6 8. Be3
Nc6 9. Qd2 Be6 10. O-O-O, 1-0 in 61, Brause - jos, ICS 1997.
Assumption 3: Black plays king's knight to f6
Idea: Ne7 after Bb4. This somewhat shifts the main course of
the game, as the control of e4 is usually the main concern in the DDG.
After Ne7, Black may continue with f5, or Nf5.
Example: 3... dxe4 4. Nc3 Bb4 5. Be3 Ne7 6. Qg4 Nf5 7. Qxe4 Nxe3 8.
fxe3 c5, 1-0 in 83, Brause - Akis, ICS 1997.
Assumption 4: Black does not play king's bishop fianchetto
Idea: g6 and Bg7. Obviously, f6 may become a dangerous weakness
because e6 has already been played. Similary, in the BDG Bogoljubow
Defence, where Black plays g6, it is not recommended to continue with
Examples: 3... dxe4 4. Nc3
- 4... f5 5. Be2 Nf6 6. Bh5+ g6 7. Be2 c6 8. Nh3 Bg7, 0-1 in 72,
Brause - Mus, ICS 1997.
- 4... Nf6 5. f3 exf3 6. Nxf3 g6!? 7. Bg5 Bg7 8. Bd3 Nbd7 9. O-O c6
10. c5 Qc7 11. Qd2 O-O 12. Rae1 Nd5 13. Nxd5 cxd5 14. Bh6, 0-1 in 46,
Montenero - Hover, 1997.
Assumption 5: Black castles kingside
Idea: Having developed the queen's bishop, Black could try
castling queenside: after e5 and Bg4, or Bd7 and Bc6, or b6 and Bb7.
This may be difficult to achieve, but at least it would destroy
White's typical plans; e.g., the half-open f-file would be almost
useless. Brause has met O-O-O a few times, usually after Black has
played 4... f5.
