Help needed to find a Swedish opening It appears that openings are named after almost any country or city in the world. Spanish opening, Italian game, French defense, Hungarian gambit, London system and so on. 

Because I am from Sweden I want to learn and play an opening related to Sweden. But to my surprise and dismay I haven't found a single one named after a Swedish location or Swedish chess player (Scandinavian Defense doesn't count because it is for the whole of Scandinavia).

Can you help me find one? The more closely related to Sweden the better.
The Swedish Variation of the Tarrasch Defense is the move 6...c4 in the line below. The name is also used for the same plan in slightly different positions with the same pawn structure.

[FEN ""]

1.d4 d5 2.c4 e6 3.Nc3 c5 {Tarrasch Defense} 4.cxd5 exd5 5.Nf3 Nc6 6.g3 c4 {Swedish Variation}


Its ECO code is D33. Black tries to capitalize on his queenside majority, while White is going to play e2-e4. I think theory considers the line dubious right now.

There is also the Göteborg variation in the Najdorf Sicilian, famous for its origin story. In 1955, one of the Interzonal tournaments was held in Göteborg, and in round 14 it happened that three Argentinian grandmasters (Panno, Pilnik and Najdorf) had black against three Soviet grandmasters (Geller, Spassky and Keres). All three reached the position below with the new move 9...g5 that the Argentinians prepared beforehand, and all three Soviet players reacted with the same piece sacrifice 11.Nxe6 and won.

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5 e6 7.f4 Be7 8.Qf3 h6 9.Bh4 g5 {Göteborg Variation} 10.fxg5 Nfd7 11.Nxe6 fxe6 12.Qh5+ Kf8 13.Bb5


I think it's considered drawish these days.
