I think it started as Rymdskorpionen (the space scorpion) and got shortened to just Skorpionen.

Supposedly it should be The Scorpion in english as well, but maybe he wasn't sure of the english spelling?

Anyway, I've always supposed that the name comes from black's set-up vaguely resembling a scorpion with pawn c5 as the sting...

This line looks like fun! Any idea why it is called the "Scorpio" Defense?  ???

Like most of Martens' ideas it hasn't been very widely published.

He had some short articles in a swedish corr-magazine called 'SSKK-bulletinen' in the late 80s, which dealt with the Scorpio, Kamtchatka gambit, Snake Benoni, North Sea defence and Gaw Paw Sicilian - which still are are the most known of his inventions.

Martens himself was quite a strong player in the late 60s, he won the swedish championship once and held a young Ulf Andersson to a 3-3 tie in a match in 1968 or 69. Then he left chess for some kind of politics, briefly resurfacing every time he'd happened to invent some new opening...  Grin

Looks pretty interesting.  I had never heard of this before (I miss "The Myers' Openings Bulletin" which kept me informed about a lot of these unusual openings.)  I may try this out in some speed games.

To me, it seems that if White doesn't overextend, White has the advantage as Black really doesn't have that much counterplay. The defense is very playable and is a much better weapon than most other rare defenses.

Still no replies?  Perhaps this should be under Nimzo/Benoni instead - though it seems like a daring defence to me  ???

Anyway, here's a few examples from recent practise, showing some of the potential of this defence:  Cheesy

How about The Scorpio Defence?

A daring defence that has always looked very logical to me, is another Martens' invention: The Scorpio defence:

1.d4 e6 2.c4 c5 3.d5 ed5 4.cd5 d6 5.Nc3 Ne7 6.e4 Ng6 intending Be7-f6, 0-0, Re8 etc. In short holding e5 with just about every piece if necessary, while playing for b7-b5 as in most benonis. Not having weakened f6 and h6 may also be a big plus, since this and the stronghold on e5 makes it different than most benonis, while keeping many of the good sides of the benoni structures.  Cheesy

Some people seem to think it doesn't work due to white just playing f3, maintaining a slight space advantage, but I just can't believe that black shouldn't be OK in those positions.  Cheesy
