ChessFlash - Initial Diagram Position Option

ChessFlash now includes an option for displaying an initial position other than the starting position. This allows you to show the final position or any particular position that occurs in the game (not in analysis) as the first position. Here is an example using a game of Morphy's. White to play and win (you could use this with the "Board only" option to hide the pgn move / text area).

The changes for this new feature were contributed by Etienne Dupuis.

Open Source ChessFlash

As I just posted at ChessFlash.com I intend to make the source code available for the ChessFlash Viewer available under an open source license. I need to research some different open source licenses and consider a few other issues but I plan to do this fairly soon.

Part of my motivation is a relative lack of time for customization and new features. I wrote ChessFlash while not otherwise employed last year but I have started back working at a "real job." I've had some customization requests that would make the ChessFlash Viewer better and more widely used.

Does anyone have thoughts / advice / words of wisdom on the matter?

Big News

At the Flash On The Beach (FOTB) conference in Brighton, Sr. Director of Engineering at Adobe Systems Paul Betlem, confirmed that Adobe is indeed developing a Flash Player for the iPhone. However, Apple calls the shots as to when it'll be available.

... He said (not direct quote) "My team is working on Flash on the iPhone, but it's a closed platform." He noted that Apple makes all the decisions, so in other words, the ball is in Apple's yard at this time. If Apple says yes, Adobe will have the player available in a very short time.

Flash for the iPhone confirmed at FOTB
How far behind can ChessFlash on the iPhone be? But that's not the "Big News." The "Big News", of course, is that now (or soon) I have an excuse to buy an iPhone! I mean invest. Invest in a iPhone.

In the meantime I do need to get back to posting tactics here and working on additional ChessFlash features...

Daily Tactic July 30, 2008

Morphy-Jefferson, New York simul, 1859. I am giving away the ending, but the game ends with the mating pattern know as Philidor's Legacy. Morphy sets it up with two Deflecting moves. To help learn this pattern and solidify it, practice going over the final moves in your head from move 19 to the end. Once you learn the pattern or if you already know it, go over the game in your head from move 17 onwards to practice your visualization skills.

Deflecting is forcing an enemy piece away from some useful position. In this game Morphy deflects the black queen off of the d8-h4 diagonal. Decoying is attracting an enemy piece to a square useful for you. In this game as part of the final mating pattern, a black rook is decoyed to the f8 square.

Morphy-Conway, New York simul, 1859. This game is played at rook odds and features the tactical device of zwischenzug.
The zwischenzug (German for "intermediate move"), is a chess tactic in which a player, instead of playing the expected move (commonly a recapture of a piece that the opponent has just captured) first interpolates another move, posing an immediate threat that the opponent must answer, then plays the expected move.

Morphy - Thompson, New York, 1859.

How good a chessplayer was Paul Morphy? Let’s look at a match he played against James Thompson, a man thought to be one of the top dozen American players. Giving him the outrageous odds of a Knight, Morphy beat him 5-2! After looking over Morphy’s games, Fischer said that, given time to study modern theory and ideas, Morphy would beat any modern player (except Fischer, of course!).

Morphy-Anderssen, Paris, 1858.

Karl Ernst Adolf Anderssen ... is generally considered to have been the leading chess player in the world from 1851-1858 and 1861-1866. He was "dethroned" temporarily in 1858 by Paul Morphy, who announced his own retirement from chess in 1859...

For the next few years Anderssen was considered by many people to be the world's best player, ... Then in late 1858 he was beaten 8-3 by the American champion Paul Morphy in a famous match held in Paris, France (2 wins, 2 draws, 7 losses). Although Anderssen knew as well as anyone how to attack, Morphy understood much better when to attack and how to prepare an attack...

Anderssen played the curious opening move 1. a3 in 3 games of his match against Morphy, and broke even with it (1 loss, 1 draw, 1 win). This opening move, now referred to as "Anderssen's Opening", has never been popular in serious competition.

Morphy made it look easy against the second best player in the world. In the final position, Morphy played a strong move and then Anderssen resigned. What was Morphy's winning move? It does involve a Deflection followed (in the main line) by a Pin.

Update: I am in the process of adding a mute/unmute button and when that is done I will have more posts with sound/voice.

On the home front we will be getting a new Air Conditioner installed Friday and will be much cooler after that. We are getting a respite from the heat with some rain and more possible soon (Hello, Dolly!). Actually, I don't think Dolly is expected to affect us much in Houston except for some additional, needed rainfall.

Today's game is Morphy-Lowenthal, 1858.
He was one of the first masters to play a match against Morphy after the latter's arrival in London in 1858. Morphy won with a score of nine wins, three losses and two draws. "...I am convinced that I was vanquished by superior strength," Löwenthal said about the match, as reported by the Englishman Frederick Edge. No doubt aware that chess was Löwenthal's only source of livelihood, and conscious to not be considered a professional player himself, Morphy after winning the match stakes of £100, presented Löwenthal with a gift of furniture valued at £120 for his new house.

The very last move of the game (which I have removed) is a nice tactic featuring a Deflection sacrifice that will win due to a Pin and Skewer. A Deflection is forcing an enemy piece to move away from an advantageous square. So, what is Morphy's winning move in the final position?

The colors are reversed compared to yesterday. Today it is Morphy as White against Harrwitz in Paris, 1858. The opening transposes into a Ruy Lopez: C62.

After 30. c5 Harrwitz takes on c5 with his rook setting up a combination that would not work if the rook is still on the seventh rank -- do you see why? Morphy then delivers the fatal blow with 31. ?

Harrwitz - Morphy, 1858 in Paris.

Harrwitz was born in Breslau (Wroc?aw) in the Prussian Province of Silesia. He established his reputation in Paris, particularly as a player of blindfold games. He lost a match in England to Howard Staunton in 1846 at odds of a pawn and two moves, and drew a match with Adolf Anderssen in Germany in 1848.

Harrwitz lived in England from 1849, and founded the British Chess Review. In 1856 he moved to Paris, where he won a match against Jules Arnous de Rivière. In 1858 he played a match against Paul Morphy in Paris. Harrwitz won the first two games, but lost the match 5½-2½. Harrwitz withdrew from the match, allegedly on grounds of ill health. He subsequently retired to the Austro-Hungarian county of Tyrol, dying in Bolzano in 1884.

In today's game I believe the simple maneuver (tactic) that Morphy executes on moves 39-41 is very instructive.

The Opera Game was a famous chess game played in 1858 between the American chess master Paul Morphy and two strong amateurs, the German noble Duke Karl of Brunswick and the French aristocrat Count Isouard, who consulted, playing together as partners against Morphy.

The game is often used by chess teachers to demonstrate the importance of rapidly developing one's pieces, as well as other lessons.

Henry Bird - Paul Morphy. London, 1858.
In 1858 he lost a match to Paul Morphy at the age of 28, yet he played high-level chess for another 50 years. Although Bird was a practicing accountant, not a professional chess player, it has been said that he "lived for chess, and would play anybody anywhere, any time, under any conditions." In the New York tournament of 1876, Bird received the first brilliancy prize ever awarded, for his game against James Mason.

Another Morphy game against John Owen at "pawn and move" odds. Owen is known for Owen's Defense and was a strong chessplayer:

In 1858 he won a game against Paul Morphy, which led to a match between the two. Despite being given odds of pawn and the move (meaning he started the game with an extra pawn and always moved first), Owen lost the match 6-1, never winning a game.

His performance in the 1862 London tournament, the first international round-robin event (in which each participant plays every other) was more impressive - he finished third, ahead of future world champion Wilhelm Steinitz, and was the only player to win against the eventual tournament winner, Adolf Anderssen.

How incredible is it that Morphy could win a match at odds against a player of his caliber?

In today's tactic Owen takes Morphy's bishop on h3 (he should have played Qc5 instead). How does Morphy continue? And, bonus question, why does Owen resign when he does? I'll put Fritz's answer in the comments.

In yesterday's Daily Tactic, Morphy and Barnes played an exhibition game against Staunton and Owens. Today Morphy takes on his partner from that consultation game: Thomas Wilson Barnes. Mr. Barnes is noted for eight career wins against Paul Morphy and the Barnes Opening and Barnes Defense:
Barnes Defense is named after Thomas Wilson Barnes, an English master who, amazingly, defeated one of the greatest players of the time, Paul Morphy, with it in an offhand game played in London in July 1858

In today's tactic, Barnes will develop his knight to a3 and then Morphy's next two moves are stunning! Can you find them?

Today's tactic is from the First American Chess Congress in New York in 1857.
The first American Chess Congress, organized by Daniel Willard Fiske and held in New York, October 6 to November 10, 1857, was won by Paul Morphy. It was a knockout tournament in which draws did not count. The top sixteen American players were invited. First prize was $300. Morphy refused any money, but accepted a silver service consisting of a pitcher, four goblets, and a tray. Morphy’s prize was given to him by Oliver Wendell Holmes, Sr.

In this game Morphy is White and Louis Paulsen is black. After Paulsen moves his rook to safety, how does Morphy put him away quickly?

Paul Morphy and Daily Tactic June 22, 2008

Paul Morphy was born in New Orleans on June 22, 1837 (thanks BlunderProne).

Today's Daily Tactic is Paul Morphy against No Name in New Orleans 1849. Morphy is about 12 years old at the time.

No Name plays knight takes d4 with a double attack on Morphy's Queen. When you are in a situation like this, you have to ask, are you feeling lucky? What Would Morphy Do? Or, in this case, what did Morphy do?

Happy Birthday Paul Morphy!

In 1850, when Morphy was twelve, the strong professional Hungarian chess master Johann Löwenthal visited New Orleans. Löwenthal, who had often played and defeated talented youngsters, considered the informal match a waste of time but accepted the offer as a courtesy to the well-to-do judge. When Löwenthal met Morphy, he patted him on the head in a patronizing manner.

By about the twelfth move in the first game, Löwenthal realized he was up against something formidable. Each time Morphy made a good move, Löwenthal's eyebrows shot up in a manner described by Ernest Morphy as "comique". Löwenthal played three games with Morphy during his New Orleans stay, losing all three.wikipedia

Sneak Peek

Here are sneak peeks at: Puzzle Mode and Study Mode.

These will be very limited features in the first version.

I'll write more about them later today....

Update:In both the Puzzle Mode and Study Mode, the Viewer plays one side and you play the other. The Viewer is not "thinking", it is just following the PGN file and playing the next move in sequence after you move. The Puzzle Mode and Study mode are basically just slight variations of the same mode. There is only one line that you can play against the Viewer for each variation, but the Viewer can play multiple variations (see the Opening Example).

You can enter your moves by clicking the from and to squares on the board with the mouse (in any order and with other clicks in-between --- it is very lenient). If you prefer, instead of entering the move, you can press the "play" button (right arrow under the board) and the Viewer will make your move too.....

The puzzles have a FEN string embedded in the HTML so the viewer knows what initial position to show before loading the PGN file. The Study example could also do that if needed. It could even be an end game position to study...

About the same result. Trying...width=100% and height=550 seems to be the biggest I can make the viewer that works for me in both IE7 and FF3 on my laptop and still have the viewer fit in a single screen.

Updated July 8 to use the latest version.
I've been working on creating a tool that can be embedded in blogs to display chess PGN files. The tool and the supporting web site are now in beta testing. I'm looking for a few brave bloggers to try it out and give feedback.

Update: Here's one brave blogger.

Ideally, you already have a blog or a web site, play chess and already know what a PGN file is.

If you're interested, you can sign up at http://chessflash.com/.

Here is my game against Rocky Rook in the recent LEPer tournament. Another one is starting soon, see http://www.liquideggproduct.com for details.


And, a big thanks to likesforests who has already done some great testing and provided some great feedback.

More PGN Viewer

Updated June 23 to use latest version.
I made these colors match my blogger template after the complaints about my previous red and green "christmas theme". Now, I expect complaints about my blogger template colors. :) The layout demos a "compact layout." The layout options and colors are specifed as parameters in the html that embeds the viewer (take a look at the page source if you are interested in the gory details).


A scrollbar has been added! Yeah!
The game is my game against Kevin Gafni in the recent LEPer tourney. He won the tournament and this game. I played the opening pretty well but went astray around move 26 when I was surprised by his Rd4 (I'd overlooked that he could play it). I may have played on a bit too long but with two rooks on there were some chances... (analysis by Fritz)

Feedback on the game and the viewer are welcome!

Tabbed PGN Viewer

(Updated July 8 to use the latest. Updated June 3, 2008 to use V0-046. Updated June 3, 2008 to use the latest version of the viewer and different colors. The left board was green and the right board was red.)

Here is another (see previous post) sample of the ChessFlash PGN Viewer, this time showing the Saavedra Position. The point of this demo is to show the concept of the "tabbed variations" board on the right. As you scroll through the main line using the buttons on the green board, note the "tabs" on the red board and try clicking those to see what happens. Does it make sense to you? You can also click in the text area.


All feedback and bug reports are welcome.

ChessFlash PGN Viewer Test

(Updated July 8, 2008 to use the latest. Updated June 3, 2008 to use V0-046. Updated June 3, 2008 to use the latest version of the viewer and different colors. The left board was green and the right board was red.)

This is a test to check embedding this viewer and using it in different browsers. The game is mine against Polly in the recent LEPer tournament.

The viewer is live. Click the buttons, click the moves in the text area. Experiment -- it should mostly make sense.


The green board is for viewing the main line and the red board is for viewing variations (click a variation move in the text area to load it in the red board). A number of new features are planned including "tabbing" the variations board to select among parallel variations.

Adobe Flash 9 is required. If you can see the viewer, any feedback is appreciated. If you can't see it in your browser, please let me know.
Update: A bug has been found and fixed: at the end of the game or at the end of a variation the "Side to Move Indicator" (black or white box at bottom right of the board) was incorrect.
