Hadron, you said that ALL contributions to this thread, not just mine, seemed to be uncritically accepted computer analysis. How do you justify that?

But as to my 5...d5, any thoughts of your own about it? I have some variations, but I've been waiting for any sort of reaction before sharing them. Your thoughts?

As for 5...d5, it did indeed spring from my thinking. I am quite surprised to discover that machines recommend it. Here on vacation, I am using Shredder running on a Samsung Galaxy Tab, a very weak machine. But in any case, it does not recommend the move in question.

Stefan, I don't think that Black has any problem castling kingside under the "threat" of g4, g5 and so forth if he stays active enough.

@All: I'm surprised that nobody has reacted to my proposal of 4...d5 in reply to 4.f4,. And say, Hadron, does that idea look like computer chess to you?

The following game was "played in the Fyfe Gambit Tournament at Glasgow, and awarded half the brilliancy prize," says The Times Literary Supplement, April 19th, 1917, p. 192. We cannot criticize a brilliancy prize game, or can we?

So many heretics here, me included! Shouldn't we trust the genius of Fyfe? He was a recognized expert in his field, and a respected chess player as well, almost as strong as Sheriff Spens, mastermind from Glasgow. Fyfe analyzed without an engine. But before I fall back to his ingenious 4.f4 (could my line be wrong?), another look at 4.Nf3.

Hadron, you are a stalwart of human thinking. The engines are limited, yes. After 1.e4 e5 2.Nc3 Nc6 3.d4 Nxd4 4.Nf3 Nc6 5.Bc4, what can Black play? Perhaps 5...h6 6.Qd5 Qe7 7.Qd3, White is three tempi ahead. According to Tarrasch, three tempi are worth a pawn - no engine needed here.

Smyslov-Fan, your sample game leaves me speechless. I guess it needs a Fyfe Gambit with a brilliancy prize to outbalance it. But for the moment, the following game (also U14) will suffice. I think that kylemeister is basically right that the position with Qg3 hasn't enough bite. So White's goal should really be the expansion with g2-g4-g5, to gain space and prevent Black from castling short. Next, he must outplay Black, due to his pressure on the d-file and his activity. Really, where is Black's counterplay?
