Blackmar-Diemer in Scandinavia

Michel Wiander won a Blackmar-Diemer Gambit that began as a Scandinavian Defence in Sweden. Roy M. Nilsson accepted the gambit as Black. They played the BDG Ziegler Variation 5...c6. This Caro-Kann Defence usually sees 6...Bf5. The game shifted gears with 6...e6. It became a BDG Euwe Variation 5...e6 by transposition.

White had played Bc4 instead of Bd3. Black had played ...c6 instead of ...c5. No worries. On move 9 Black played ...c6-c5, and on move 13 White played Bc4-Bd3. The winning tactic in this game is 14.Bxh7+ Nxh7 15.Bxe7.

[My London 2.Bf4 Playbook is a similar repertoire.]
