Is that in the same way that 1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Nxd4 Qh4 refutes the Scotch Game?   Grin

Try harder.  I think you'll find 1.e4 e5 2.d4 exd4 3.c3 Qe7 more promising and even then things are not so simple.  Early queen forays have a cost.

Take for example 1.e4 e5 2.d4 Qh4 3.Bd3 exd4 4.Nf3.  How do you expect to hold on to the pawn?  4...Qf6 5.Bg5 Qb6 6.0-0 Qxb2  Black even gets another pawn!  7.Nbd2 Nc6 8.Rb1 Qxa2 and another! (8...Qc3 9.Nc4 and Bd2 next, trapping the queen; 8...Qa3 is best, but after 9.Nc4 Qc5 10.e5 is pretty miserable for Black {edit:  well, maybe not so terrible for Black after 10...a6}; Rb5 is a tactical idea here that White may eventually play under favorable circumstances.) 9.Nc4 Qa4 10.Bd2 Any takers for Black now?

Final edit:

I'll leave the above as a sample line, but I think 8.Nc4! is more accurate than 8.Rb1.  A possible continuation is 8.Nc4 Qb4 9.e5 a6 10.a4 when the plan of Bc1-a3 is very dangerous for Black.

what about 1.e4 e5 2.d4 Q-h4. blacks second move wins a pawn.with Qh-4.and there is no defense against  e4 e5 2.d4 Qh-4.[color=#cc0000][/color]

I didn't say that I used a computer to help produce my moves for correspondence play.  I said that I use the computer for openings research (or at least, that is what I meant to say), without saying anything about how I prepare my moves for correspondence chess.   

I am not sure of the value of a computer for chess training, but I think its of very great use in preparing openings variations.

After 3...Qe7 4.cxd4 Qxe4+ 5.Be2 the only game I know is:

Alekhine,A - Cheron,A [C21]
Vevey, 1925

1.e4 e5 2.d4 exd4 3.c3 Qe7 4.cxd4 Qxe4+ 5.Le2 Qxg2 6.Bf3 Qg6 7.Ne2 Ne7 8.Nbc3 c6 9.Nf4 Qd6 10.0-0 f5 11.Re1 Qc7 12.Qb3 Na6 13.Ncd5 Qa5 14.Re5 cxd5 15.Nxd5 Kd8 16.Bg5 1-0.

Müller/Voigt also give 7...d5?! (iso Ne7) 8.Nf3 Qf5 9.Nxd5 Bd6 10.Nbc3 Ne7 11.Nxe7 Qe6+ 12.Be3 Qxe7 13.Qb3 c6 14.0-0-0 0-0 unclear, Corbat,P - Morin,S corr IECC 2002.
M/V suggest 7...Nf6 and an old suggetion of Mikenas is 7...Bb4. In general my computer only gives -1.46 and normally that would be reason, to raise my interest (it means more than +0,5 silicon compensation!). So when I say, that I don't trust it, it is only because I don't see how White should continue. That again merely shows my lack of chess understanding.

What I do understand, is that 5.Be2 Bb4+ is quite lame. White gets about the same positions as after 5.Be3, but can try to find better moves than directly transposing with a quick Be3. What I don't understand is the benefit of 5.Be3 Bb4+ 6.Nc3 and 7.Be2 compared to 7.Nf3. Black gets the option of snatching an extra pawn; if this is too dangerous, then he just can transpose as White has to play 8.Nf3 anyway. Moreover I am not convinced, that the bishop should be on e2 iso d3.


I concede that 5.Be2 Bb4+ is lame.  No safe route for Black here.  Sad

Muller/Voigt doesn't give a lot after 5...Qxg2.  (In fact, they give 5.Be2 a '?'.)  After 6.Bf3 Qg6, besides the line with 7.Ne2 you quoted, they just give "7.Nc3 Bb4 -/+ (ECO)."  Not too helpful!  Seems kind of murky to me.  Not only is Black behind in development, but his queen is stuck out in the open.  How does Black develop?  I don't have an answer yet.  I think I would actually prefer to play White!

As far as my tendency to be materialistic goes, I have been that way for a long time since I was a junior.  I am tenacious defender of difficult positions, but I've had a number of downfalls.  In the past, getting into difficult positions wasn't necessarily something I would plan, but I would simply get myself into them by underestimating compensation.  This is something I am trying to correct partly by studying gambit play.  For my level (~1950 USCF last time I played), I would actually consider myself tactically strong, but I am a bit shortsighted in some strategic situations.  In my opinion, there is often a strong positional aspect of gambit play that is backed up by tactical strength.  I am working at developing a feel for these positions.  Maybe it would be more productive if I used a computer for navigation.  However, I sometimes feel it is better training to spend the effort to understand the position from scratch.  From this standpoint, I feel reluctant to invest in an engine.  I never thought of this as a pressing matter, but maybe I've put it off for far too long.

Also, I'm talking about how best to offer the Danish Gambit, not the Half-Danish.


The Half-Danish is a new opening for me. Maybe because it has one Swedish (Von Lindehn) and one Russian parent (Alekhine)? All opening sources I know (and the only relatively recent one I don't know is Lukes) see 4.Nxc3 as a part of the Danish Gambit. If 4.Nxc3 really deserves a seperate name - which I find quite useless, as 4.Bc4 d6 5.Nxc3 just transposes - Alekhine Gambit is more appropriate.
Whatever you name it, from the beginning I have displayed my preference for 4.Nxc3 above 4.Bc4. That is also my starting point for the question, if 2.d4 or 2.Nf3 Nc6 3.d4 is to be preferred. The idea 16.h5 Rc8 (I assume 17.hxg6 Ba3!), which puts the double sac quite out of business indeed, only confirms this point of view.

After 3...Qe7 4.cxd4 Qxe4+ 5.Be2 the only game I know is:

Alekhine,A - Cheron,A [C21]
Vevey, 1925

1.e4 e5 2.d4 exd4 3.c3 Qe7 4.cxd4 Qxe4+ 5.Le2 Qxg2 6.Bf3 Qg6 7.Ne2 Ne7 8.Nbc3 c6 9.Nf4 Qd6 10.0-0 f5 11.Re1 Qc7 12.Qb3 Na6 13.Ncd5 Qa5 14.Re5 cxd5 15.Nxd5 Kd8 16.Bg5 1-0.

Müller/Voigt also give 7...d5?! (iso Ne7) 8.Nf3 Qf5 9.Nxd5 Bd6 10.Nbc3 Ne7 11.Nxe7 Qe6+ 12.Be3 Qxe7 13.Qb3 c6 14.0-0-0 0-0 unclear, Corbat,P - Morin,S corr IECC 2002.

I think that 5. Be2! is very a good move, and so is 5. Be3 Bb4+  6. Nc3 Nf6  7. Be2!  It seems to me that X and perhaps some others are a little too impressed by silicon's evaluation of the resulting positions.  Silicon will almost always tell you you're winning if you're two pawns up and it can't see a clear way for your opponent to mate you or regain his material.  But as you will know, there are plenty of two-pawn-up positions where you're not only not winning, but worse (e.g. the Compromised Defense to the Evans).  Objectively here perhaps, Black is somewhat better.  But he sure isn't just winning, and I wouldn't want to be Black with the clock ticking.  In fact I would rather be White OTB.


5. Be3 Bb4+  6. Nc3 Nf6  7. Be2!

Interesting idea, but as my last post indicates, I already see some problems with 6...Nf6 right now.  6...d5 was my original preference, and it still is.  I don't use "silicon" to evaluate positions, just my own stupid ideas and moves.  (As folks like MNb can testify, if I am using an engine, it's pretty crappy.)  I suppose you are talking about my reference to Kaufman's book which uses computer aided analysis?  This also is an old idea used by Rubinstein.  I guess you could me accuse of being materialistic, but whatever... think whatever you want to think.

I think 5.Be2 is an interesting.  When I am first looked at accepting the pawn, I could not find an acceptable defense for Black.  (I still don't see one.)  It was surprising, so I wrote the "without a lot of  thought" part.  I think it is better to play 5...Bb4+ 6.Nc3 d5 7.Nf3 Bf5.  I don't see yet how this improves on 5.Be3, although I have not looked at it for that long.  Do you have any additional ideas for white here?

In several lines, Black has a concrete means of defense that holds his position together.  In some other lines, Black doesn't quite make it and White has excellent compensation.  I have argued for both sides, so I would appreciate it if you did not pull the "silicon card" to invalidate everything I have written.  I don't really think you mean it this way, but in a public forum this is kind of how it comes across, especially when there was someone earlier posting one move assessments and game scores without comment.

I actually started this thread to see some more ideas from the white side, and I appreciate your analytical contributions.  I would be happy to see more resources for white in the 5.Be2 line.

To partly answer my own question:

1.e4 e5 2.d4 exd4 3.c3 Qe7 4.cxd4 Qxe4+ 5.Be2 Bb4+ 6.Nc3 d5 7.Nf3 Bf5 8.0-0 Bxc3 9.bxc3 looks promising for White:

a)  9...Qc2 10.Qxc2 Bxc2 11.Re1 seems to give White excellent compensation.  What does Black do with his king?

b)  9...Nc6 10.Re1 0-0-0 11.Ng5 Qe7 12.Bh5 (12.Bg4 Qd7 holds) looks dangerous for Black.  I think Black has problems here.

Maybe Black's best is 5...Qxg2?

To end this message without a lot of thought, I'll just say 5.Be2 looks really desperate!  Not that I am saying the Black position looks enjoyable after accepting the pawn.  I'd have think about that.  2 pawns up and saddling the opponent with 3 isolated pawns is really tempting!  But my first impression is that Black is OK if he plays it safe with 5...Bb4+ 6.Nc3 d5, when white's bishop on e2 is not on its ideal square. 


As I said to MnB, I think Be2 on move 5 or 7 is good, in either case before committing the g-knight to f3.  How many isolated pawns White has is hardly important when he's already two pawns down.  In fact, he'd much rather have the half-open g-file than not.  5...Bb4+ 6.Nc3 d5 and White can switch back to 5. Nf3 with reasonable compensation.  There is nothing wrong with the B on e2.

It's not unclear.  Black just crushes White after 16...Rc8!.  I saved this for years and finally got to play it as follows:

1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.c3 dxc3 5.Bc4 cxb2 6.Bxb2 Bb4+ 7.Nc3 Nf6 8.Qc2 d6 9.O-O-O O-O 10.e5 Ng4 11.Nd5 Bc5 12.exd6 cxd6 13.h4 Nce5 14.Ng5 g6 15.Ne4 Bf5 16.Bxe5 Nxe5 17.h5 Rc8! 18.hxg6 Ba3+ 19.Kb1 Bxe4 20.Qxe4 Rxc4 21.Qe3 fxg6 22.Qxa3 Rxf2 23.Qxa7 Qf8 24.Ne7+ Qxe7 25.Qxf2 Rb4+ 26.Ka1 Ng4 0-1  Good, Gary - Morss, Mark US 13th CC Ch. Final.

White also has 11. h4 which perhaps is a little less clear, though I would still much prefer Black in CC.  OTB as I have said, I would rather not skate so close to the edge.   

Also, I'm talking about how best to offer the Danish Gambit, not the Half-Danish. 

I think that 5. Be2! is very a good move, and so is 5. Be3 Bb4+  6. Nc3 Nf6  7. Be2!  It seems to me that X and perhaps some others are a little too impressed by silicon's evaluation of the resulting positions.  Silicon will almost always tell you you're winning if you're two pawns up and it can't see a clear way for your opponent to mate you or regain his material.  But as you will know, there are plenty of two-pawn-up positions where you're not only not winning, but worse (e.g. the Compromised Defense to the Evans).  Objectively here perhaps, Black is somewhat better.  But he sure isn't just winning, and I wouldn't want to be Black with the clock ticking.  In fact I would rather be White OTB.

Parismagique's idea 13...f5 looks pretty good. So maybe White must try 13.a3 Bxc3 (Ba5 14.Rae1 f5? 15.Nxd5) 14.bxc3 and 15.c4. 3.c3 Qe7 4.cxd4 Qxe4+ 5.Be3 Nf6 6.Nc3 Bb4 7.Nf3 Nd5 8.Qd2 Qe7 9.Bd3 (iso 9.Bc4) might also be an idea; Nf4 10.0-0 Nxd3 11.Qxd3 Bxc3 12.Qxc3 or even 12.bxc3 with a serious lead in development.


In the line 9.Bd3 Nf4 10.0-0 Nxd3 11.Qxd3 Bxc3, after 12.bxc3 I think white gets serious pressure that fully compensates for the pawn.  I prefer the pawn capture since white can meet ...d5 with a later c4.  This doesn't look very promising for black to me.  I don't see anything better than 9.Bd3 Nxe3 which transposes back to the line black was trying to avoid (and I still like white's compensation there).

Alekhine's 4.Nxc3 perfectly avoids the Schlechter Defence, which only arises after 4.Bc4 cxb2 5.Bxb2 d5.  Wink In fact after 4.Nxc3 Black's best lines include ...Nc6 at some point; then White has the choice of x.Nf3 or x.Nge2. The only annoying extra option for Black is 3...Qe7, the main subject of this thread! Granted, ...Nge7 is annoying too, but White does not avoid that one with Göring's move order.

I don't trust Mikenas' idea 3...Qe7 4.cxd4 Qxe4+ 5.Be2 either, though again games are lacking. Who knows?

Parismagique's idea 13...f5 looks pretty good. So maybe White must try 13.a3 Bxc3 (Ba5 14.Rae1 f5? 15.Nxd5) 14.bxc3 and 15.c4. 3.c3 Qe7 4.cxd4 Qxe4+ 5.Be3 Nf6 6.Nc3 Bb4 7.Nf3 Nd5 8.Qd2 Qe7 9.Bd3 (iso 9.Bc4) might also be an idea; Nf4 10.0-0 Nxd3 11.Qxd3 Bxc3 12.Qxc3 or even 12.bxc3 with a serious lead in development.

All this stuff confirms my judgment, that 3...Qe7 is an interesting defence, but not a proven refutation yet. The well prepared defender will net quite a few points, as the surprise factor is turned against the gambiteer. Müller/Voigt hardly spend two pages on this little move, where Schlechter's Defence receives about 14 ...

You don't need Firnhaber's tricky 13...Bxf2, of which I am suspicious, you just play 13...Nce5! with ...Rc8 very soon.  Also I didn't say that this is too dangerous to play over the board, only that I myself prefer not to.

It's a matter of opinion, I think we can agree, whether the Danish or the Goering move order is the best way of reaching these gambit positions. You allow a host of strong defenses, Schlecter's not the least, when you play the traditional move order.

1.e4 e5 2.d4 exd4 3.c3 Qe7 4.cxd4 Qxe4+ 5.Be2 !? and if Qxg2 6.Bf3 Qg6 7.Nc3 Bb4 8.Nge2 with Rg1 Bf4 etc. time is money !


13...f5 looks good to me.  Compared to Davies' line the extra tempo (...c6) black gets out of 8...Qe7 seems to make a big difference.  White just doesn't have the same tactical resources to get a break in the center.  So maybe this suceeds as a more ambitious attempt.  9.Bc4 looks a little suspect to me, since it loses a tempo compared to the analogous line (8...Nxe3) given by Davies.  But if 9.Bd3, 9...Nf4 is now a possibility.  Discuss.

So I was a little lazy when I looked at this line.  It would be cool if this works.  Good ideas.

To end this message without a lot of thought, I'll just say 5.Be2 looks really desperate!  Not that I am saying the Black position looks enjoyable after accepting the pawn.  I'd have think about that.  2 pawns up and saddling the opponent with 3 isolated pawns is really tempting!  But my first impression is that Black is OK if he plays it safe with 5...Bb4+ 6.Nc3 d5, when white's bishop on e2 is not on its ideal square.

I tend to agree with MNb, but I would say that Danishes give a sugar rush which dissipates through the course of the game.  However, the stickiness of the frosting that accumulates on the pieces may provide nuisance compensation for the sugar low in the endgame.

Pardon me for intruding with some thoughts about chess.  The Danish fails rather simply in what has historically been regarded as its main line: 1. e4 e5  2. d4 exd4 3. c3 dxc3  4. Bc4 cxb2  5. Bxb2 Nc6  6. Nf3 Bb4+  7. Nc3 Nf6  8. Qc2 0-0  9. 0-0-0 d6  10. e5 Nfg4.  This used to be considered quite dangerous for Black, but it has been solved.  White's main problem is that 11. Nd5 Bc5  12. h4 fails to 12...Ncxe5! and if the exchange occurs on d6, Black's queen rook leaps into decisive action on c8.  That is my understanding, anyway.  There are certainly other good ways of playing against the Danish, but if there is an outright refutation, this is certainly it.  

On the other hand, if someone simply wants easy equality, it is much more clearly obtained by 3...d5 than by 3...Qe7.  Everyone knows about 3...d5 4. exd5 Qxd5  5. cxd4 Nc6  6. Nf3 Bg4  7. Nc3 Bb4  8. Be2 Bxf3  9. Bxf3 Qc4 =.

On a purely theoretical level JN may be right that the Danish just throws two pawns away, but in any given practical setting, it is unlikely to be so simple.   I only accept it in CC, never OTB.  

The problem with the traditional Danish move-order is that Black is given so much leeway.  For example he has 3...Qe7, not a bad move, not a new or necessarily winning one either, but annoying.  If someone wants to play the Danish, and this could make sense especially for young and improving players, better start with the Goering move order and then offer the second pawn, as recommended by MnB.  If you simply must play gambits, versus the Petroff, you can always play the Boden-Kieseritzky or even the Cochrane.


Theoretically the Danish is refuted by the variation Markovich gave indeed according to Müller/Voigt, though Markovich is a little imprecise:

1.e4 e5 2.d4 exd4 3.c3 dxc3 4.Bc4 cxb2 5.Bxb2 Nc6 6.Nf3 Bb4+ 7.Nc3 Nf6 8.Qc2 0-0 9.0-0-0 d6 10.e5 Nfg4 and now either 11.h4 Ncxe5 12.Ng5 g6 13.Nce4 c6 (Harding) or 11.Nd5 Bc5 12.exd6 cxd6 13.h4 Bxf2 (Firnhaber). See for details Müller/Voigt's book.
Markovich is also right, saying that this is too complicated and risky to try OTB.

But he is wrong, saying that the Göring move order is to be preferred. While this avoids 3...Qe7, it gives Black extra possibilities (especially the sharp 4...Nf6 5.e5 Ne4). It also denies White some options, especially 1.e4 e5 2.d4 exd4 3.c3 d5 4.exd5 Qxd5 5.cxd4 Nc6 6.Be3. This is equal, but avoids the far less interesting 6.Nf3 Bb4+ (or Bg4 7.Be2 Bb4+ 8.Nc3) 7.Nc3 Bg4 8.Be2 Bxf3 9.Bxf3 Qc4 10.Bxc6+ bxc6.

The simplest way to obtain equality, I have stated this several times, is 3...Ne7 (or 4...Nge7 against Göring's move order). The idea of course is to get an improved version of the Capablanca line. Everybody also knows, that a knight is a better blockading piece thant the queen. Where the Capablanca line (3...d5) gives White the choice between a complicated middle game (6.Be3) and a dead draw (6.Nf3), 3...Ne7 preserves winning chances for Black.

Above all Markovich forgets to mention the version Alekhine preferred: 1.e4 e5 2.d4 exd4 3.c3 dxc3 4.Nxc3. Black is theoretically OK, but not more than that. This is what I would recommend to youngsters etcetera. This way the Danish remains playable, despite of all fast food swallowing couch potatoes. In fact I would say, that their health might improve by playing the Danish more often.  Wink It would get their adrenaline running faster.

When I say "refutation," I tend more to use the Eric Prie interpretation, rather than the "show me a clear advantage in all lines" interpretation.  If white is struggling for equality and black is forcibly directing the course of play, I consider that line to be unplayable and that effectively black has "refuted" white's system.

In accordance with conventional wisdom, I suppose I should concede 3..d5 is the better move.   (Oh, who am I to argue with "everyone?")  But I really like 3...Qe7, and I don't think it is too difficult to defend if he plays the "premature" 6...d5.   Grin

Daives himself in  (Play 1 e4 e5 ) as well as Marin (Beating the Open Games) recommend 3...d5 as a safe way to eqaulize. 

I have to agree with Markovich here that is it quite easy to produce reams of analysis refuting a gambit in a message board. It is another to face it over the board unexpectantly. I always find it more pratical to decline espesically when I can get a comfortable position declining and resist the temptation to prove a point.

You are probably right! However, this does not make the Danish a sound opening. Nor does it solve the problem posted in the title of this thread.

Some people like to eat chips for breakfast, burgers for lunch, and candy all day long while doing nothing but watching TV. They "don't mind". They "like such simple plans". Yet, it’s a scientific fact that such a lifestyle is highly unsound, and that the mortality rate among fat fast-food-eating, TV-watching people is much higher than the average mortality rate in society.

So. If your ambition in life is to become as fat as you can - then by all means eat that fast-food. And if your ambition in chess is to throw a pawn away for very little compensation (if any) when you play with the white pieces - then by all means play that Danish gambit.


Wow.  I don't know where to begin.  The irony is overwhelming.  This is just too easy...

Thanks for the laugh.  You made my day?

Actually, I think you'll find the mortality rate for both groups is exactly the same ...

Ah, so that's where all those one move assessments come from.  I'm still behind the times.  I am bit of a chess Luddite.  I have had several bad experiences with people accusing me of cheating with a computer in blitz on the Internet.  I like using Bookup and ChessBase Light though (but no engine! grrr!).

Sometimes I wish chess had an anti-computer rule like they have in professional shogi.  (I believe professional shogi players are prohibited from playing matches against computers.)

See HgMan's appropriate thread in the General Section. Before trusting silicon verdict, it is necessary to enter a few more moves. After 10...c6 my computer gives -0.81. After 15.Bxe4 it has dropped to -0.42. That is a good sign for the gambiteer.

I think there's a little more here to prove...  Smiley  Even if black gets in ...d5, white gets something of an automatic attack.  It may not be enough, but I certainly think white gets tangible compensation for the pawn.  Maybe it offers better winning chances than the other line, but I think Black's defensive task is more difficult.

I realize this is different (8...Nxe3 instead of 8...Qe7), and your line improves on this with the addition of ..c6, but a continuation in Davies' book is:

8.Qd2 Nxe3 9.fxe3 Qe7 10.Bd3 d5 11.0-0 Bxc3 12.bxc3 0-0 13.Rae1 f5 14.c4 dxc4 15.Bxc4 Kh8 16.e4 fxe4 17.Ne5 Bf5 18.g4 Nd7 19.Nf7+ Rxf7 20.Bxf7 Bxg4 21.Bd5 Nf6 22.Bxe4 Nxe4 23.Qf4 Be6 24.Rxe4

I may be wrong, but I think a lot of gambit players wouldn't mind playing positions like this.

Nah... instead of the premature 6. - d5 black should play 6. - Nf6 and transpose to the game Nogrady-Krivolapov, 1996:


1.e4 e5 2.d4 exd4 3.c3 Qe7 4.cxd4 Qxe4+ 5.Be3 Nf6 6.Nc3 Bb4 7.Nf3 Nd5 8.Qd2 Qe7 9.Bc4 Nxe3 10.fxe3 d6 11.0-0 Bxc3 12.bxc3 0-0 13.e4 Be6 14.Bd3 Bg4 15.e5 Bxf3 16.Rxf3 dxe5 17.dxe5 Qxe5 18.Re1 Qc5+ 19.Kh1 Nc6 20.Rf5 Qd6 21.Rd5 Qh6 22.Qe2 Qf6 23.Rf5 Qd6 24.Bc4 g6 25.Rd5 Qf6 26.Rd7 Qxc3 27.Rxc7 Rad8 28.Rf1 Kh8 29.Bxf7 Qe5 30.Qf2 Rd2 31.Qh4 Qf5 32.Re1 Rxf7 33.Qxh7+ Kxh7 0-1

I agree, 8.Qb3 Nc6 9.Bb5 looks better.  Kaufman gives the continuation 9.Bb5 Bxc3 10.bxc3 Nf6 11.0-0 0-0 12.Bg5 Qe6 13.Bxf6 Qxf6 14.Qxd5 Rad8=.  With such a narrow path to equality, it's hard to be enthusiastic for the white side.  It's funny how 3...Qe7 and 3...Ne7 are such rare lines despite their strength.

Boy, oh boy!  Now there's some fun for white!


4.Qxd4 Nc6 is a kind of Centre Game, with a lame pawn on c3.

4.cxd4 Qxe4 5.Be3 Bb4+ 6.Nc3 d5 7.Nf3 Bf5 and here I like 8.Qb3 Nc6, Mieses-Rubinstein, Lodz 1905, 9.Bb5 better than 8.Rc1.
So refutation might be too optimistic. As I have made clear a few times before, 3...Qe7 is a respectable move. The only objection is, that 2.Nf3 Nc6 3.d4 exd4 4.c3 Qe7 makes much less sense. So for practical reasons I recommend 3...Ne7 instead.
These two moves (3...Ne7 and 3...Qe7) were important reasons for me to give up the Danish, though I never met them.

This strange looking 3...Qe7 does indeed look like an interesting way to play for a win against this rare gambit. Hard to believe that such a move could give Black a good game, but it appears to work.

Well, I should add that there's always the reasonable 4.Qxd4, when I think white is able to equalize here!  Yay.

Although Black easily gets the ...d5 break, the game doesn't look completely dead to me.  So maybe I was overreacting, but this is a pretty easy way for black to get out of the gambit into a fully equal position.

Refutation of the Danish?

As discussed in the General Chess forum, Davies' recent gambit repertoire book, Gambiteer I, recommends the Danish Gambit.  While looking at his recommendations, I decided to see what Kaufman's repertoire book recommended for the black side.  It was at this point, a move stopped me dead in my tracks:

1.e4 e5 2.d4 exd4 3.c3 Qe7!

This move really seems to kill all of white's fun in the Danish.  3...d5 isn't terribly exciting, but you don't really have to worry about being worse, and there's still a game to play.  But 3...Qe7!--it just looks terrible for white to me!

Here's what looks like the main hope for white in this line:

4.cxd4 Qxe4 5.Be3 Bb4+ 6.Nc3 d5 7.Nf3 Bf5 8.Rc1 c6 9.Be2 Nf6 10.0-0 Qe7

"and White's compensation for the pawn is inadequate."--Kaufman

Davies quotes Voigt-Rausis, Hamburg 2000, which after 8.Rc1, runs 8...Qe7 9.Bd3 Bxd3 10.Qxd3 Nf6 11.0-0 0-0 12.Bg5 c6 13.Rfe1 Qd6 14.Nh4 Nbd7 15.Nf5 Qc7 16.Qh3 ("gave White good attacking chances"--Davies).  In the game, White soon won back the pawn with Nxg7 and Qh6+, and later won the game.

I am not completely convinced of White's compensation in this line, but Kaufman's 8...c6 seems to be an improvement, since it seems Black effectively wins a tempo compared to Voigt-Rausis, as White plays Be2 to castle kingside.  It looks to me like White will have to spend time to move the bishop from Be2, if he's going to make progress on the kingside.  (What else does white play for here?  A minority attack on the queenside?)

If white plays by analogy with Voigt's plan in Kaufman's line (after 8.Rc1 c6 9.Be2 Nf6 10.0-0 Qe7):

11.Bd3 Bxd3 12.Qxd3 0-0 13.Bg5

Then the disruptive 13...h6 is a new possibility available for Black with the inclusion of ...c6 protecting d5.

Maybe there other ideas for white, but I don't see anything that looks fruitful.  

Perhaps I am very pessimistic since I am not a true gambiteer, but I there a few things I find very disconcerting in this line (3...Qe7).  First of all, it avoids all of the main theory on the Danish and it is still very strong.  Second, the ideas in this line are very simple and not difficult to learn as black.  It seems like white's options are severely limited and black is directing the course of play.  Third, this is recommended in a major repertoire book that an 1...e5 player is likely to have, regardless of strength.  Put these together and you have a gold mine for the black player.  To me, it is a bit like "discovering" the move 2...d5! against 1.e4 c5 2.f4, but even worse for the white player.  (OK, this is a different type of position, but black is turning the tables on white.  A lot of players stopped playing the Grand Prix with 2.f4 after people started playing 2...d5 regularly.)

Time to forget about playing the Danish?  (Well, maybe I could make an exception for blitz.)
