In the previous tutorials we have shown the possibility to analyze games quickly even without necessity to leave the ChessBase program /OpeningMaster database/ environment. The fact is however, the database environment is more useful when doing the database operations like sorting, finding position, showing statistics of possible moves who played this already and displaying the individual games.
If we would like to get involved in the real analysis of the game, the database environment is not so necessary because even though the number of game in the database does matter it is only in the opening phase, or eventually the game has not been added to the database yet and if not you have to help yourself. You can search the world wide web via broadband internet or any computer with available internet access for other source.
Principally we need to distinguish between analysis of opened game and analysis of the ended game with known result. Both types of analysis are interesting for increasing knowledge level of the player.
The ended game is a snapshot of the recent time or far back to the past. It can be own or somebody else’s game, GM level or lower. In any case the game analysis has certain features which can be used everywhere. Let's look at the most frequent tools when analysing the ended game
The Opening Master Database is great when analyzing the ended game mainly due to openings (8 -25 moves) which can be compared to the other games which have been already played. Please refer to the separate sections / reviews of Opening Master.
The GUI help a lot when analysing the game. There are several GUIs which are world famous such as FRITZ, Chess Assistant, Chess Opening Wizard (formerly known as Bookup). Generally speaking each interface can work with certain type of data formats and certain types of engines. Unlike in ChessBase DB where engines run only in so called native format with extension .eng. in other environments (e.g. GUI) we know engines of so called
1) Open up your own GUI (in our case we use FRITZ GUI - it is assumed this Graphical Interface is successfully installed on your PC, if you don’t have it we suggest to purchase the license separately but of course you may be also working with other GUIs of your preference)
2) Set up Opening Master as your default DB. Go to: Menu -> Analysis -> Full Analysis. You must be set on ‘ended game’ and set “Opening Reference”. In the “reference DB screen, selecting the right folder where Opening Master 1.0.x is located.
Setting up of the time depends on how much you want your engine to spend on analysis of a certain position. After the analysis has started, the engine analyzes the game from backwards to front. Once the analysis is finished your first step is completed. After a closer look at your analysis output, you realize what you like about it and what not. This tool is also using the typical phrases of positions. Sometimes they are good and sometime not. You can delete it using ‘Menu-> Insert’ and change text before or after the move.
Second step involves deeper analysis in certain situations which you consider as important. Here you can as well use the automated tools offered by GUI programs. Go to: Menu-> Analysis-> Deep position analysis. Setting is self-explanatory.
The goal of each analysis is the end result which should be then saved as separate file and return to it in the 3rd step after while to see if you didn’t miss anything. Many authors of chess books suggest returning to your own game to analyze it so you can see where you could play differently with stronger move, what opponent missed and what could be learnt from the analysis. In any game you learn from each point of analysis, nobody is perfect and therefore the analyses are being made so in the future the chess player can avoid his own mistake or better to say avoid somebody s mistakes.
Each analysis takes certain amount of time, and it is not possible to cover all aspects of it in this short tutorial because engines have their specific characteristics just as the computer chess itself. The selection of appropriate engine requires knowledge of features and capabilities of the engine as well its strength. The knowledgebase describing this is also very long thus we will cover the most important facts only.
The analysis of the open game is a technical as well as ethical. In his book, Smith, R.: Modern Chess Analysis, Gambit 2004, ICCF Grand Master and US Champion Robin Smith for the first time opened up a dilemma on using computer analysis in the correspondence chess. The computer analysis is no longer a domain of correspondence chess players. We all know even the best players use the team of advisors and computer analysis so they have ready novelties in the openings or playing unexpected moves in the already played novelties.
Smith in this booked showed many weaknesses of the engines and inability to pick their results of analyses. Therefore you need to strictly differentiate supporting analysis which helps chess player to verify if he didn’t do any blunder moves (big mistakes) or looking if the variety of known moves is complete or not. Also the dynamic or interactive analysis simulates possible course of the game however nobody knows if players will play it – only the future will show it.
It is possible to play a position using static approach using engines with “infinite time icon on FRITZ GUI” analysis. In depth of 20 half-moves the analysis is not completed and over 22 half-moves already useless. The results between these two figures are also questionable just as the entire analysis. Already R. Smith and many before defined engines with limited horizon view. They are not able to know what will happen after their analysis is performed. As we know the game is not set in 10 moves therefore many players use their intuition when guessing the future of the game.
When human while analyzing a game uses the engine to simulate an opponent. This analysis is bit more advanced as static one when player is simulating the answers using the engine. The problem is that many engines don’t understand or partially understand certain moves or don’t have them recorded at all. So which engine to choose from when doing the interactive analysis? The answer is the experience with the engine itself or faith the engine will not come up with anything better anyway. However this is NOT true at all. Many sharp positions which engine “Rybka” never sees, older engine “Junior” sees quite well. Almost all transitions into the endgame are heart attacks for all engines.
The value-add of the engines is far less important than many chess beginners would think of.
It is probably the most supportive analysis and goes far beyond the two above mentioned. The rules are simple : from given position you can run engines against each other to simulate the evolution of the game.
a. Shootout – two same engines play against each other
b. Round Robin tournament – when two different or more engines play against each other in tournament .
You may select either or but the end result is to be reviewed. Everything has its pros and cons. In the shootout tournaments where same engines play against each other, one loses the variety of chess programs because the program is set to play against itself. In the Round Robin tournaments the more powerful engines beats the less powerful, but is the result correct? Does it correspond to the reality? These are the questions which one should be aware of. Therefore even in this category one may not be certain what to do next… He and she can only guess and that is the beauty of today’s chess.
You should create a great reserve when analyzing a game, anyway your next move will be done by intuition and this you get only with number of games played – sometimes 200 but sometimes already 30. (Real games, not blitz)
