All right then - here's how the Duke & Count might have prevailed over the great Paul Morphy:

[Event "rated standard match"]
[Site "Some opera house in Paris"]
[Date "1858"]
[Round "?"]
[White "Alt Morphy"]
[Black "Count Brandenberg & Duke of Isolde"]
[Result "0-1"]

<1. Nf3 Nf6 2. d4 e6 3. c4 b6 4. Nc3 Ba6>

Surprisingly modern play by the Duke and Count!

<5. e3 Bb4 6. Bd2 O-O 7. Be2 d5 8. cxd5 Bxe2 9. Qxe2 Nxd5 10. O-O c5 11. Nxd5 Bxd2 12. Nf4 Ba5 13. dxc5 bxc5>

The bishop moves proved costly in the Philidor, but in the Queen's Indian the noblemen's use of the bishops has yielded a fairly level middlegame. No quick Morphy crush here!

<14. Nd3 Bb6 15. Rac1 Nd7 16. Rfd1 Qe7 17. Nde5 Nxe5 18. Nxe5 Rac8 19. Rd7 Qf6 20. f4 c4 21. Rxc4 Rxc4 22. Nxc4 Bc5 23. a3>

Normally vigilant, here Morphy's carelessness allows a tactical shot!

<23...Qxf4 24. Qf3>

And again, Morphy fails to find a more effective continuation, 24. b4 which must cost black a piece!

<24...Qxc4 25. h3 a5 26. Rc7 Bxe3+ 27. Qxe3> 0-1

Annotating a game means adding your own notes and variations in the margins, and often includes computer analysis. Merely following one line out to a conclusion doesn't really increase understanding of the stem game. Here is an example of an annotated game, using this same Philidor Defense line = G Atwood vs J Wilson, 1801

In particular after black's (latest) mistake 7...Qe7 (best was 7...Qf6) white does not play his obvious best 8.Qxb7 but instead opts for 8.Nc3 to capitalize on development along with obvious follow up 9.Bg5

The kibitzing around what black could do on move 9 is entertaining if not terribly enlightening. Personally, if I were one of "The Consultants" playing black I would suggest to the other that we overpower white and make him switch sides. Fisher's decision to comment on the hopelessness of black's position at this point seems most appropriate.

Analyzing with Rybka 4.1 gives at first 9...Qc7 as black's best but within a second or so the chosen move is 9...Na6 which makes better sense. While 9...Qc7 unpins its knight and allows its bishop to develop, 9...Na6 allows potentially faster castling and threatens Nc5 to attack white's queen.

It does not make sense to run Rybka for days here, as the move 9...Na6 is clearly best. For grins, here is its line when depth d=23 is finished:

[+1.05] d=23 9...Na6 10.Bxf6 gxf6 11.Bxa6 bxa6 12.Rd1 Qb4 13.Rd3 Bd6 14.Ke2 Ke7 15.Qxb4 Bxb4 16.Nd1 Rhd8 17.Ne3 Rab8 18.Rhd1 Rxd3 19.cxd3 a5 20.Rc1 Kd7 21.b3 (0:37:27) 280868kN

Since black is behind in development at move 9, the worst thing is to make an aggressive move to allow the position to be easily opened. This is precisely the sort of move black chooses with 9...b5 and any reasonably strong player with white would play the sac 10.Nxb5 in an instant based on intuition, calculation is not even needed. Rybka finds this move at d=1 within milliseconds as well.

Likewise, within milliseconds, Rybka found black's obvious best response 10...Qb4+ that was not played:

[+2.46] d=1 10...Qb4+ 11.Qxb4 Bxb4+ 12.c3 cxb5 13.Bxb5+ Ke7 14.cxb4 Rc8 15.f4 h6 16.Bh4 a6 17.Ba4 Kf8 18.O–O Nc6 19.Bxf6 gxf6 (0:00:00) 0kN

At this point, the game is over, white's attack plays itself starting with 11.Bxb5+ but black again made things more fun by not seeing its obvious response 11...Kd8 that a strong player would also immediately choose:

[+5.39] d=1 11...Kd8 12.O–O–O+ Kc8 13.Rd3 Qb4 14.Rc3+ Kb7 15.Qxf7+ Qe7 16.Qc4 Qc5 17.Bxf6 Qxc4 18.Bxc4 gxf6 19.Bd5+ Kb6 20.Bxa8 Bc5 21.Rd1 Na6 22.Bd5 Nc7 23.Rb3+ Ka5 24.Rf3 Rf8 25.Bc4 (0:00:00) 0kN

What turns an even funner game into a classic comes from black's propensity to consistently choose lessor moves to help white instead of the obvious:

[+6.35] d=1 12...Qc5 13.Bxf6 gxf6 14.Bxd7+ Ke7 15.Rd5 Rb8 16.Rxc5 Rxb3 17.axb3 Kxd7 18.Rd1+ Ke8 19.Rc8+ Ke7 20.Rc7+ Ke6 21.Rxa7 Rg8 22.Ra6+ Ke7 23.g3 Rg4 24.f3 Rg8 25.Kd2 Rg6 26.b4 Rh6 27.h4 Rg6 (0:00:00) 0kN

After 12...Rd8 white plays the obvious:

[+6.72] d=1 13.Rxd7 Nxd7 14.Bxe7 Bxe7 15.Rd1 O–O 16.Bxd7 Bc5 17.Qf3 Bd4 18.Bg4 g6 19.Qf6 (0:00:00) 0kN

and black again chooses a lessor move 13...Rxd7 instead of 13...Nxd7 whereupon white plays 14.Rd1 its obvious move.

At this stage, black has a few choices where 14...h6 and 14...a6 may appear to help but 14...Qb4 is clearly best because it unpins black's knight to defend its rook and attacks white's queen. True to form, black again chooses good move for white, 14...Qe6 and white replies with the obvious:

[+10.85] d=1 15.Bxd7+ Qxd7 16.Qb8+ Ke7 17.Qxe5+ Kd8 18.Rxd7+ (0:00:00) 0kN

Black again ignores its obvious move 15...Qxd7 in hope of not losing its queen, setting up a mate in two for white which, of course he sees.

[Mate in 2] d=1 16.Qb8+ Nxb8 17.Rd8# (0:00:00) 0kN

This video is unique, I went back to a "blank sheet of paper," and started from scratch. I also used the latest engines, (Fritz & Houdini); I did discover at least one new move, (no one has cited it - at least as far as I am aware of); and I also found that one move that had been the subject of some criticism ... was the first choice of the engines, and was perfectly valid.

I have updated my web page, and the new analysis ... when you print it out, it is 11 full pages, and maybe a diagram and one comment on the 12th page. When you watch the video, you get a FREE link to that analysis. Its posted as a "PDF" file, so if you can read those type of files, you can open it and read it and save a copy to your computer ... all this is 100% free.

The new analysis is on the well-known game:
Morphy vs Duke Karl / Count Isouard, 1858.

<2.... d6 - this was probably played to get Paul Morphy out of his book.>

How much ignorance can you put into one sentence?

2) I'm not saying I'm correct, but I pronounce the World Chess Federation's acronym as <Fee-day> (French acronym), not <Fide> as in rhymes with Tide. I will sometimes just spell out each letter too - F-I-D-E.

So maybe I misunderstood something here, but it did look to me like you were saying that the concept of the double attack was elaborated by the Russians in 1958 (or later). If I am wrong, I apologize, but I think you may want to reconsider that particular passage.

All the best!
