Anderson vs Williamson in BDG

It seems to me Scandinavian Defence players must encounter the opening moves 1.e4 d5 2.exd5 almost all the time as Black. Once in a while they face 2.Nc3, 2.e5, 2.d3 or 2.d4. Experienced players have some response in mind for each one of these. How often do they face 2.d4? The Blackmar-Diemer Gambit is likely a surprise most of the time, but they know that they have to prepare something.

When Kevin J. Williamson was confronted with the moves 2.d4 at Southend, England in 2016, he captures and returned the gambit pawn. Williamson did the “walk on by” with 2…dxe4 3.Nc3 Nf6 4.f3 e3. The whole line is level in the Langeheinecke 4.f3 e3 5.Bxe3. Black often plays 5…Bf5, but Williamson played the solid 5…e6. John Anderson and Williamson are veteran players who have doubtless seen their share of tricky openings in their careers. This BDG Langeheinecke continued 5.Bxe3 e6 6.Bd3 Nbd7.

White gets a choice with his f-pawn and kingside knight. One option is to push the f3 pawn to f4, dreaming of f5 or Nf3-Ne5. But this would leave Be3 as a bad bishop, at least temporarily. Anderson chose to play 7.Nge2 Be7 8.Ne4. Players have many good choices in this line. White always has more space and easy development. Black always has equalizing continuations. Probably the higher rated Anderson hoped to outplay Black. After both went wrong on move 20, a draw was soon agreed.

This line 5.Bxe3 e6 is section 3.8 in my Blackmar-Diemer Games 2 book.

Anderson (2214) - Williamson (1950), 60th Southend Easter 2016 Southend ENG (2.10), 25.03.2016 begins 1.e4 d5 2.d4 dxe4 3.Nc3 Nf6 4.f3 e3 5.Bxe3 e6 6.Bd3 Nbd7 7.Nge2 Be7 8.Ne4 0-0 9.0-0 b6 [9...c5=] 10.Qe1 Bb7 11.Rd1 Nd5 12.Bd2 c5 13.c4 N5f6 14.Bc3 [14.Be3=] 14...Qc7 15.Kh1 Rfd8 16.Nxf6+ Bxf6 17.dxc5 Qxc5 18.Bxf6 Nxf6 19.Qc3 [19.Nc3=] 19...Rac8 20.Rd2?  [20.Rfe1=] 20...Qe7? [20...Qg5-/+] 21.Qb3 [21.Rfd1=] 21...Rd7 22.Rfd1 Rcd8 23.Nc3 g6 24.Nb1 [The knight protects d2 to unpin the bishop. Material is even. I am guessing that White offered a draw here.] 1/2-1/2
