World championship 2010 games analysed with ChessAnalyse

I will now give an introductory survey, how ChessAnalyse may be used for analysing the 12 games between Anand and Topalov. This may be helpful for users new with ChessAnalyse, too, in order to learn more about the features and handling of this powerful tool. It is recommended that you follow the steps below in order to get aquainted with ChessAnalyse.

At first let's start with downloading the 12 games as pgn files. After a quick search, I found them here on the official web site:
http://www.anand-topalov.com/en/results.html 
I copied the 12 files together in a folder and unzipped them.

1.) Now let's start ChessAnalyse Demo version (http://www.chess.com/download/view/chessanalyse-25 ). The pgn files can be imported together via File/Import Games and selecting them all (Press Ctrl+A or select the first and the last game with a mouse click while holding the shift key down). After import, I saved all 12 files again, immediately, in order to get one file for all games, which is much more easier to handle. In order to to this, you have to check all 12 games (put a checkmark in the square by clicking with the mouse) and choose File/Export Games. Restart ChessAnalyse in order to load the single game file.

2.) In the next step we will load a chess engine in order to analyse the games. If you're searching for some good free engines, take a look here:
http://www.chesslogik.com/ 
I decided to use the latest version of the Fire engine (former known as FireBird), which is now available in version 1.31 and claims to be one of the strongest engines around. I downloaded the file Fire_131_w32_KLO.rar, which is quite a small file. It has to be "unrared" after download (use 7-zip, winrar or something else). The engine executable, which has to be loaded in ChessAnalyse, is Fire_131_w32_KLO.exe. To load the engine, simply choose File/Load Engine and select this executable file. The engine should respond with "Engine status is Ready".

3.) Before analysis can start, we have to setup some engine parameters. Click Setup/Engine and turn the MultiPV parameter (4th parameter) to 3, which means that the engine will search for the best 3 moves. Click ok, the engine should respond with "MultiPV set to 3".  The other parameters shall be left on their default value.

4.) Since only those moves are analysed, that have got a check mark in the square left to the move, we have to click into the square of the first entry on the left side, which should be named "ChessAnalyse" in order to select all moves of all 12 games. (By using opening books, some moves in the beginning of a game could be ignored automatically from analysis).

5.) In order to track the analysis process it is useful to choose View/Score Chart, which turns the score chart graphic on (screen area becomes light blue). After clicking the "Analyse" button, analysis starts and will last about 1 hour. (depending on your computer) - time for a coffee or two...

6.) After the analysis has finished, the engine turns back to status "Ready" and the results should be saved to a pgn file. Here it is:

7.) Because the demo version is restricted in functionality, I will do the further evaluation only for the first game (as an example). Uncheck all games except the first one and click on Statistics/"n-Best-Moves". The following result is displayed:

This is a typical score for human players. Now lets compare the score for the two opponents separately. At first, type "Anand, V." into the "Player" field. Then uncheck the first game and check it again. Only the black moves should now be checked (be sure to type "Anand, V." exactly as the name is shown in the game tag section). Here is the result for Anand:

The same can be done for Topalov with a similar result: 

The moves of both players this game can also be analysed via the score deviation statistics. Here it is for Anand:

and the same for Topalov:

At first glance it seems that Anand made fewer moves away from the best computer move. But if we take look at the score chart (evtl. click View/Score Chart), it becomes clear that the decisive move, which turns the game to a winning game for Topalov is move no. 23 of Black with a score deviation of 0,86:

The black line (which indicates the best move score) at move no. 23 is well beyond the actual score (dark bar) for 23... Kf7, which is 0.00 (instead of -0.86 for the best move found 23... Bb7)
