Hi,
i can recommend you Grunfeld defence as a solution of your problem. It is hard opening for opponent to beat, because black has good chances for taking over the initiatives in the early part of the game. If you want learn something more, please write to me in the private message, i could send a book about this opening. And finally a short sample game in this opening:
Hi.
I have no idea how to play against that opening. I usually play volga gambit but c5 in the second move in this variation too often goes into sicilian defence where I haven't got any experience and it's too passive.
I don't mind learning something new instead of 1...Nf6, I just want to get open and active position with many opportunities.
Thanks.
