After 1...Kh8 2.Qe5 white's attack slows down a bit after 2...e1Q. A more forcing continuation is the beautiful 2.Nf7+ Kg8 3.Qxg7+ Kxg7 4.Bf6+ Kg8 5.Nh6# (don't credit it to me though, this was featured in Shredder chess puzzles today).

Here is a description of the Deschapelles Coup:

|Apr-08-11|| ||GamerMan: Not only was he the strongest player at chess, he completely dominated the field. He made morphy's dominance look even. Not only did he win vs the best players of his time, he could offer them knight odds and still win. Kudos to you Deschapelles!|
|Mar-07-12|| ||brankat: Only 5 of his games in the database?
Happy Birthday master Deschapelles.
|Mar-07-12|| ||Penguincw: R.I.O. Deschapelles. Enjoy your 232nd birthday or something.|
|May-27-12|| ||Caissanist: Like most of the wonderful old material in the Chesscafe archives, the Deschapelles article has been moved and can only be found by searching. Here is the current link: http://www.chesscafe.com/text/spinr... .|
|May-27-12|| ||Caissanist: Spinrad's piece also mentions that very few of Deschapelles' games have survived, so the five in this database are apparently all that still exist, even though he seems to have played a great deal. The article also lacks a picture of Deschapelles, so it would appear that none of those have survived either.|
|May-27-12|| ||thomastonk: <Caissanist> A few more games of Deschappelles survived as well as some fragments. As an example I mention a game with Dumoncheau played June 21, 1841, and published in La Palamede 1842.|

|Oct-13-14|| ||Bubo bubo: <TheAlchemist: This is a famous game (composition, maybe?) attributed to Deschapelles against La Bourdonnais, where only the spectacular finale is known:> |
Theo Schuster's book "Unvergessene Schachpartien" also gives only the final, but moreover claims that this game was played at very strange odds; allegedly Black started with 8 additional pawns, but w/o queen: <"Mit Weiß hatte Deschapelles seinem damaligen Schüler Labourdonnais acht Extrabauern für die Dame vorgegeben.">
I think I've seen the initial setup for this type of odds game somewhere:

|Jan-23-15|| ||jnpope: In re: "In 1842 he managed to beat Saint Amant +3 -2 =0" above, it should be mentioned this was a very unusual odds match:|
<An extraordinary sensation has been created in the Paris Chess Club, by the sudden re-appearance of the veteran chess monarch, M. Des Chapelles; this gentleman has gratified his friends by playing a match of five games with M. De St. Amant, giving very curious and unusual odds. Des Chapelles proudly proffered to give something like a Pawn and a half in each game, and thus it was arranged. In the first game the veteran gave a Rook, and received in exchange two Pawns and the move; in the second game, St. Amant gave the Rook, and took in lieu thereof, five Pawns and the move; the third game was simply a Pawn-and-two affair; in the fourth party, Des Chapelles yielded up Queen, taking in return six Pawns and the move; and lasty [sic], in the fifth battle, St. Amant gave the Queen, and received nine Pawns and the move. For some elucidation of the curious variety of Chess termed the Pawn game, see Mr. George Walker's pocket volume, called games played by Philidor and his contemporaries, as well as the earlier volumes of the French Chess Magazine, "Le Palamede". These five important games occupied three sittings of about two hours each; Des Chapelles coming off, on the whole, conqueror, winning three of the five games. Are his laurels so brilliant that even his seventy five years may not dim their hue? We say in deep truth and humility, that Des Chapelles could even now, in our opinion, give the Pawn to the proudest spirits of Britain. Of the five about named games, it is matter of regret that one only was taken down [...]>

Again, the poorly written ChessBase software I have goes bonkers if you save this game in CB format, however, it loads and plays the game just fine from a PGN file.
|Jan-30-15|| ||jnpope: So I was messing around with Rybka and checking it's evaluations at 14-ply for the starting arrays in the Des Chapelles v St. Amant odds match (where Des Chapelles was said to be giving roughly one and one-half pawns in odds in each game).|
In the first, and only published game, Des Chapelles gives St. Amant the Queen's Rook for two extra pawns (at c4 and f4) and the move. Rybka suggests Nf3 as White's best move with an evaluation of White at -4.31 centi-pawns.
In the second game St. Amant gives Des Chapelles the Queen's Rook for five extra pawns. It is unclear where the pawns are placed, but based on the four and six pawn set-ups published in the literature available to me, it seems that the pawns were placed most likely at c3, c4, f3, f4, and g3 or at b3, c3, c4, f3, and f4. In each case Rybka suggests Nh3 as White's best first move with White at -2.02 and -2.03 centi-pawns respectively.
In the third game St. Amant receives from Des Chapelles Pawn and two moves. Assuming St. Amant's first move as being 1.e4 (the most likely first move in a Pawn and two game) White's evaluation is exactly +1.50 centi-pawns for 2.d4 (and actually a little better at +1.51 for 2.Nf3).
In the fourth game Des Chapelles gives St. Amant his Queen for six additional pawns (traditionally placed at b3, c3, c4, f3, f4, and g3). Rybka suggests 1.d4 with an evaluation of -4.19 centi-pawns for White.
The fifth game has St. Amant giving up his Queen to Des Chapelles for nine extra pawns. I'm guessing the two best possible configurations for the extra pawns to be b3, c3, c4, d4, e4, f3, f4, g3, and g4 or b3, b4, c3, c4, d4, e4, f3, f4, or g3. Rybka suggests 1.b4 at -1.40 centi-pawns for White in the first case and 1.e3 at -1.63 centi-pawns for White in the second case.
We know Des Chapelles lost the first game (giving up roughly 4 pawns and not 1.5), so I'm guessing that he also lost game 4 (the other game at a roughly 4 pawn disadvantage) and that he won games 2, 3 and 5.
It makes me wish we had more games from Des Chapelles to study.

I am confused as to what -4.31 centipawns means. I believe it means -0.0431 pawns. That is, a very very small advantage to Black.
But logic tells me that <-4.31 centipawns> in fact means -4.31 pawns, a large advantage for Black.
I wonder which it is?
|Jun-19-16|| ||jnpope: I have no idea what the conversion is for Rybka's evaluation function to pure "pawns". I based the unit of measure, i.e. the centipawn, on what I found here in regard to Rybka 4.1: http://rybkaforum.net/cgi-bin/rybka...|
|Jun-19-16|| ||jnpope: I would have to go with the values as being converted to "pawns" in the Arena software I use to harness the Rybka 4.1 engine... so -431 centipawns is probably what Rybka evaluated the position as and it became -4.31 pawns as converted by Arena. So my mistake on bungling the conversion units.|
|Jun-25-16|| ||dernier loup de T: Talisman; maybe you did not notice that Deschapelles seems to have played only ONE chess game in his life, not four or more...|
|Jun-27-16|| ||Stalwart: TheAlchemist's post is a beautiful composition. I included it in my book about forced mates of masters.|
|May-02-18|| ||Cibator: <Aug-02-13: Oliveira: A portrait of Deschapelles: http://en.wikipedia.org/wiki/File:A...|
Well I wouldn't swear to the authenticity of that portrait. It shows a mature man with bags under his eyes and crows' feet. Age at least early thirties, possibly older. (You can't see the jawline, which could have provided useful confirmation of the age-range.)
Thing is: Deschapelles (b 1780) would have been that age from about 1812 onward. But the hair style shown in the picture - queue at the back, tied with a ribbon - would surely have well out of date by then.
