The second game of the World Chess Championship 2014, between the world champion Magnus Carlsen and challenger Viswanathan Anand, was played on 9 November.

New functionality

From now on it will be possible to use NAG symbols (Numeric Annotation Glyphs) like $1 and $15 in the chess game viewer, because these symbols have recently been added. Below you can find an example.
Please note the text that becomes visible when you place your mouse above one of the less trivial symbols.



The code used above is:

This post demonstrates the use of two chess boards in an article about chess which may be useful when you want to publish a game with a lot of comments and/or variations.

This post is intended as a demonstration of the Chess Game Viewer that we have configured in the previous posts. I have used some different styles to show that you can change the lay-out and the colour of the fonts.

Smothered mate!

It seems to work rather well, but let me know in the comments if you experience some difficulties.

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.

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.

This game publishing method stooped working and the content of the post is replaced by an image of the original screendump.

Chessdom is covering the Valjevo Chess Event:

Three players leading after the fantastic round with four decided
games
Atalik scores first win ever against Nikolic. Roiz tactically outplayed
Stojanovic and Karpov forced Iodrachescu to give up after the threats on the
back-rank. Damljanovic played perfect Rook endgame to beat Pavasovic.

Damljanovic B. (2585) - Pavasovic D. (2567)

This is the start of this very interesting Rook endgame.
White certainly has the best possibilities, but it is not easy to win the game.
