After 6.Nf3, I found only one game in the Chesslive DB and it's not even a GM game. It's rather interesting, though, and worth renewing the discussion. The move Black played here is 6...Ng4!?
Maybe not too well-played by White but, as I said, just trying to keep this discussion going. I will try to give some more ideas as I am quite fascinated with the Icelandic Gambit.
So Boris Alterman covers the Icelandic gambit in his gambit guide, and he mentions a sideline of Bc5 instead of the standard Bxe6. He says it is "playable even at the master level, but mostly just for fun". The line is very interesting to me and I have won several blazing victories off of it, but unfortunately he only mentions Bc5 and shows no analysis, and I cant find any resources about it online, so everything ive found is original ideas. I was hoping you guys could help me find some ideas after Nf3, which appears to be whites strongest reply.
Any ideas on how to improve the line would be appreciated!
