what mean you are the best move for hvite

i mean black. sorry

If I was playing the Blackside I will put two diagrams up to show how I would play not nc6

I'll see you when the tournament starts in 2-3 days.Good Luck

In the OP's original position, I think 3..Nf6 is best.

I like gambits see my post above on Albins counter gambit and Budapest gambit. there are two others but I'll show you in the Quickknockout tourament
