Scandinavian opening turned into Blackmar-Diemer Gambit
2... dxe4 3. Nb1c3 Bc8f5 4. f3 Ng8f6
Blackmar-Diemer Gambit declined. Vienna defense.
5. Bc1f4
Recommended is fxe4, though the Bishop is on a good square so it's not urgent. Still, as long as the f-pawn is at f3, white's king side remains paralyzed.
5... e6 6. Qd1e2 Bf8b4
Protecting indirectly the e-pawn by pinning the Knight.
7. O-O-O
? Frees the knight, but after the exchange the king is left exposed.
7... Bb4xc3 8. Qe2c4
? Gives up on recapturing the bishop.
8... Bc3xb2
!? I considered Ba5 to save the Bishop and protect the vulnerable pawn at c7, but Qb5+ Nc6 Qxb7 Kd7 Bb5 did not look good at all. Still doesn't.
9. Kc1xb2 c6
Vital, blocking the a4-e8 diagonal, protecting c7, and opening the d8-a5 diagonal for the black queen.
10. Bf4g5
the priority right now would be to get the rest of the white officers to play.
10... Qd8b6
Not a strong move. O-O or Nbd7 would've been better.
