I only had the nerves to try the HAG in some corr games , mostly with draw results . I would love to try it in otb games but at least you are a piece down and i think its easier to defend and a lot time consuming to find accurate moves to keep the attack going . Here is an example , well the Knight at f1 later is not the happiest horse in the world i agree ..

  I don't have enough time to compare thoroughly right now, but the conclusion in that thread was that in the line 8.d4 Nf6, White seemed to be getting fully adequate compensation in the line 9.Bxf4 Bb4 10.Bd3 d6 11.0-0. 


Other treatments are available. I don't like playing the Bishop to b4 when I think it is needed near home on e7. If you are going to play it to e7, why not park it there before playing Nf6? This creates an additional threat of taking on h4. White can ignore this by Qd2 or 0-0. But can Black take it? Some of the examples may not appear encouraging for Black, for example this postal miniature.



If you switch on an engine to check the final position, it suggests 14 .. d5 with a winning advantage, the point being that 15 Nxd5 can be met by Kxf7 and 15 Bxd5 can be met by Nge7 and there's no mate.

Another correspondence miniature is this one.



A nice demonstration of the possibilities of the Bxh6, Qg5 idea, but the fairly obvious culprit is the move Na5, chasing the Bishop to a square which makes the Bxh6 stuff work.

I was actively involved in that thread mentioned by Tony37.  I don't have enough time to compare thoroughly right now, but the conclusion in that thread was that in the line 8.d4 Nf6, White seemed to be getting fully adequate compensation in the line 9.Bxf4 Bb4 10.Bd3 d6 11.0-0.  8...f3 (strongly supported by Brabo, also given as Micawber's main line) appears to be the most critical test, although White's chances are still better there than in the "pure" Allgaier.

You may find a lot of answers in the famous KG-files from Micawber in this forum some years ago. I attached the "Hampe-Allgaier"-part for developing the discussion.

I would happily play white in this position every time. After 12. O-O white appears to have full compensation. More importantly, isn't this precisely the type of position white was hoping to play?

Anyone who plays the KG regularly is a romantic at heart and harbors dreams of playing beautiful games. 8...d6!? looks like the start of something wonderful...

Regarding the 8...Nf6!? variation, here's some fuel for the fire that shows white doesn't lose and actually has a good chance at playing for the win if black isn't careful.

There's a lot of analysis of the Hamppe-Allgaier in this thread:
http://www.chesspub.com/cgi-bin/yabb2/YaBB.pl?num=1208413606/all

I think the Hamppe-Allgaier is a draw with best play, while the Allgaier proper is clearly a win for black

I defended this recently using a set up with pawns on d6, g4 and h6, the King on g7 and the Knight and Bishop on f6 and e7.

There a lot of material in an old article by Tim Harding at http://www.chesscafe.com/text/kibitz79.pdf which quotes theoretical verdicts that this plan  is too passive. In counter to that, Black has an extra piece, so he will generally win after consolidation and simplification. If you check previous games with an engine, you usually find that the tactics weren't played with complete accuracy and that positional verdicts have been derived mostly from the game result. For example there's a game quoted Lauckner-Terpstra where Black chases the Bishop on c4 back to d3 and then falls into Bxh6+ Rxh6, Qxg5+ where h7 is no longer available to the King. If you don't fall into that trick, placing the Knight on f6 would still be playable.

The relevant line runs 1. e4 e5 2. Nc3 Nc6 3. f4 exf4 4. Nf3 g5 5. h4 g4 6. Ng5 h6 7. Nxf7 Kxf7 8. d4 d6 9. Bxf4 Nf6 10. Bc4+ Kg7 11. Qd2 Be7 . It would also be possible to play Be7 before Nf6 introducing the possibility of taking the h4 pawn or provoking g3. There's also a possible set up with the Bishop on f6 and the Knight on e7.

f7 and h6 are weak spots. One engine idea is to cover both of them with Rh7 and Kh8
