Alekhine - Capablanca 1927

The 34th game of the 1927 world chess championship match between Alekhine and Capablanca is a classic example of the technique to win by placing a rook behind the own passed pawn. The game is shown as a demonstration of the LT-PGN-Viewer.

Update April 2010
This method to publish chess games doesn't work anymore. For demonstration purposes the following screendump is shown.

How to use the LT-PGN-Viewer

Some people have asked me how to use the LT-PGN-viewer on their blog site as I have done in the post about the LT-PGN viewer and editor. It turned out that showing the code that was used in this post made it clear. The code I have used in that post is:

<iframe src='http://www.lutanho.net/pgn/ltpgnboard.html?Init=&ApplyPgnMoveText=1.e4 g6 {The modern defense}<|br> 2.Nf3 (2.d4 {is played more often.})<|br><|br> 2...Bg7 3.Bc4 d6 4.O-O Nf6 5.Nc3 O-O 6.d4 c5 7.dxc5 dxc5 8.Be3 Nc6 9.Bxc5 Qxd1 10.Raxd1 Nd7 11.Ba3 Bxc3 12.bxc3 Nf6 13.Rfe1 Rd8 14.Rxd8+ Nxd8 15.Bxe7 Be6 16.Bxe6 fxe6 17.Bxf6 Nc6 18.Nd4 Rf8 19.Nxc6 Rxf6 20.Nxa7 e5 21.Nb5 Rc6 22.h3 Rc5 23.Nd6 Rxc3 24.h4 1-0 &SetBGColor=FFFFFF&SetImagePath=cases27|&eval=AddText(%22<|td><td><B>Modern defense example<|B><BR><BR>%22+GetHTMLMoveText(0,0,1))' width='550' height='355' frameborder='0'></iframe>

Please note that the moves were not visible when viewing the page in FireFox as mentioned in the problem with FireFox post. This has been solved in the posts that I have published this year by creating an addtional html page. An example of this method can be found in the post Some traps in the Sicilian game.


Update:
The problem with FireFox has been solved by the programmer as you can see in the original post.

Mission accomplished

I suppose that my search for a way to publish chess games on a blogspot site has been successful as you can see in the previous posts. The mission has been (at least partly) accomplished.

Now the solution meets the following requirements:

• A chess board that shows the position after each move
• The moves are shown
• Clicking on a move shows the position on the board after this move
• Autoplay
• It should be able to add variations
• Comments between the moves are possible
• Based on entering PGN-like moves
• Without the need to copy and paste all kind of code
• And not depending on the site of another person or company.

At the moment I haven't looked at the following wishlist

• A possibility to hide the moves (= solution) for puzzles
• Everything integrated within a single blogspot template

The original requirements can be found in this older post.

Some traps in the Sicilian game

This post shows some of the traps in the Sicilian opening and may be useful by itself, but the main purpose of this post is to give a demonstration of the possibilities of publishing chess games on a blogspot site.

Update April 2010
The method stopped working and the post has been replaced by some images taken from a screendump from the original post.

Magnus Carlsen

As a kind of follow-up on the previous post Aronian and Carlsen became the co-winners of the Corus tournament. On the Magnus Carlsen Chess site the game of the previous post is described in the following way.

As white, Anand sacked a pawn against Kramnik and the latter avoided repetition of moves only to be allow Anand a ferocious attack against the black king. However, Kramnik defended brilliantly and after Anand missed Rd1 and gave up his bishop instead, his advantage disappeared. With queens off the board, a draw was agreed in the rook + 4 pawns versus rook + bishop + 1 pawn ending, and the winners press conference could begin.

A nice blog about the adventures of the youngest chess grandmaster in the world.

Anand-Kramnik (Corus Chess 2008)

Another example game:

This is the game Anand-Kramnik which was the game in GM-A that took the longest time to finish. Around move 45 it seemed that Anand was winning. Kramnik’s king got more and more into trouble, and Anand could take two pawns on the queenside, but he missed 51.Rd1!, the move suggested by Fritz.
If Anand had won this game he would also have been the winner of the tournament.

The Lolli Attack with 7...f6

This is just an example game (taken with permission from the WordPress Chess Teaching blog) of another way to publish chess games with the LT-PGN viewer that probably also is working in Firefox.
I'll describe this method in more detail later, if needed.
