Actually I think it's a mistake for Black to accelerate White's development in this way.  After 6...Nxe5 7.Nc3 White's obvious plan is to go Nf4-d5, Be2, 0-0, and ram his f-pawn to f6.  I once defeated CC-IM John Mousessian with this.  White can also consider playing on the queenside.

I think a great many people assume that this system is innocuous because of the funny-looking knight deployment to h3.  But it's a big deal to have this piece on f4 instead of f3, and worth the investment of time to get it there.

@SWJediknight:  I think the pawn on c4 potentiates Nh3 because it strengthens White's control of d5.  Black's analoguous ...f5 would be rather weakening, besides his e5 knight resting on a lousy square to fight for e4.

I always thought the most critical response was 4.Bf4, when Black has a choice between the risky (but ambitious!) 4...g5 and 4...Bb4+ 5.Nbd2 d6, and the fairly sterile positions after 4...Nc6 5.Nf3 Bb4+ 6.Nbd2 Qe7 7.a3 Ngxe5 8.e3 (not 8.axb4?? Nd3#) when White may have an edge.  White can of course play 6.Nc3 but as far as I'm aware, 6...Bxc3+ 7.bxc3 Qe7 8.Qd5 f6! is currently considered to give Black decent compensation.

I must admit I know no theory after 4.e3 and 4.e4, but I always thought that if those sorts of lines were not considered too critical against the immediate 1...e5, then surely Black's chances in the analogous lines of the Budapest (where White has played c2-c4) can't be too bad.

5...g6 is the suggested reply by Moskalenko (and others I think, but can't remember where)

Anyhow, Gurevich-Tisdall the usually cited game.

Nh3 given by shershevsky in Soviet Chess Conveyor book, right?

The big question though is what is the 4th problem.
ie; what to play on move 4.

Are lines after 4.Bf4 mostly likely the best way for White to try and maintain as much advantage as possible? Whereas 4.Nf3 are the safe way of playing without risking too much?
I looked at the 4.e4 lines - Didn't like. I think white risks too much against a prepared Black, but maybe a dicey try against a much weaker opponent?

Classic 

I'm not sure why anyone plays this opening, but always figured that it was because they were hoping for 4.e4 and not one of the main lines.

In any event, the first big problem with relying on the Budapest is that White may play 2.Nf3, in which case you need a completely different defense.  The second big problem is that White may play 2.c4 . . .

In a 12 Chapter book, he devotes 5 Chapters on this system with  4.e4 which he (Taylor) claims "is the critical test of the Budapest Gambit."
