The Viking-French-Blackmar-Diemer-... attack

I already played my opponent from yesterday evening a year or so ago. At that time, he accepted the f3 pawn and was swept away by a berserk attack. Have you ever seen the series "Vikings" ? Well, I looked like Ragnar Lothbrok and England was there to conquer.

Yesterday evening, my opponent choose the more cautious path - he initially declined the offered pawn but could not resist lateron.

Black steers into a French-like defense

Vikings on the horizon !

Vikings have set ashore and immediately set camp.

6...Nxd2 7.Qxd2
King Aelle of Northumberland believes he won the first battle, but Ragnar sees it differently.


7...Bd6 8.Nf3 Nc6 9.Bd3 e5 ?
It is strange what the sight of a berserk viking does to man. King Aelle should have tried to reduce the viking forces by 9...Nb4, and if this fails, set up an outpost with Nd5.

Now Ragnar makes a premature attack, but king Aelle doesnt really benefit from this mistake.

The remainder of the game is of no interest to us - we dont want to witness the massacre that Ragnar imposes on the poor English defenders. But the suggested Viking attack certainly has some potency in it - especially as the defender is likely to make mistakes when faces with this unusual attack.

Editors note : This story is historically correct - vikings got into contact with chess when they travelled the seven seas, Ragnar did invade England, king Aelle suffered a terrible blow, and yes, the vikings would have played the Blackmar-Diemer if it had already been invented...
