What would be black's best answer to 1.d4 f5  2.e4 fxe4  3.Nc3 Nf6  4.Nh3 ...?

Thanks for showing us the opening for Dutch Staunton Gambit

d5?

you can also avoid the staunton completely with playing e6 before f5. you risk ending up in the french defence but i dont think many d4players are prepared for the french:) i rather play french than black side of staunton gambit

I can't even find 4.Nh3 in my opening encyclopedia, not even as a foot note. I suppose e6 followed by d5. Staunton's gambit realy isn't all that scary, fxe4 happens in alot of dutch lines anyway, especialy the classical ones

believe me people good with the stauntongambit can give you a really really hard time

e5?

Can you guys post a digagram of what you guys are talking about

That's what I do. It's a great way to avoid the anti-Dutch lines if you play the Classical or Stonewall Dutch, but it doesn't work for those who want to play the Leningrad Dutch.

As for the original question, I agree with e6, then d5. There's a Staunton Gambit trap that black can walk into by playing d5 too early, though I don't think it'll work quite as well for white after moving his knight to h3 for no obvious reason. Playing e6 first prepares d5 better, for much the same reason that e6 before f5 avoids the Staunton Gambit.

d5 immediately. Nh3 looks silly.

I can't seem to find any good replies with 4. Nh3. 4...d5 looks logical but the position looks solid

I can't seem to find the logic behind the move 4.Nh3

3 alternatives for White are: 4.g4, 4.f3 or 4. Bg5. I think 4.Bg5 looks strong.

Well he spelled it out for you: "What would be black's best answer to 1.d4 f5  2.e4 fxe4  3.Nc3 Nf6  4.Nh3 ...?" Except the Nh3 is a novelty it seems..

Why not show the Eduard Lasker - George Thomas 29 October 1912 variation of the Staunton Gambit?
