· Remove previous analysis - if this is checked then any previous analysis by an engine will be removed
· Finally you can select which side of play you wish the engine to analyse the moves of White , Black or both sides .
Please note if you analyse the same game with different engines or with the same engine but a different time per move then it is important to set an Annotating engine name to help distinguish which engine the analysis came from .
Click OK to begin the game analysis . The game analysis is performed in reverse order from the end of the game to the beginning of the game . This helps improve the analysis especially with HIARCS chess engines which learn from their previous analysis and can use that information of future outcomes as the analysis progresses backwards through the game .
As the game analysis progresses HIARCS Chess Explorer will use the chess engine ' s analysis of the moves and variations to annotate the game with chess symbols to indicate where blunders , poor , dubious , interesting and good moves are found and add alternative variations to the Game Notation pane where they are considered useful .
As the game is analysed the current move being analysed is displayed in the History & Statistics view . For example :
The progress of Analyse Game is also shown in the progress bar at the bottom of the HIARCS Chess Explorer window . You can also cancel the analysis in progress by clicking the [ x ] next to the progress bar .
Endgame tablebase access
Endgame outcome information is available in endgame databases called Nalimov tablebases . Any engine supporting Nalimov tablebases can utilise your local endgame tablebases . The folders to access these databases should be set up in the Engine preferences tab along with the Nalimov cache setting .
While having tablebases stored locally can be useful for analysis , they do take up a lot of storage space with 6 piece tablebases taking up about 1,000 Gb of storage . Also acquiring all this data can be very time consuming and even expensive , some retailers sell a small subset of the data on multiple DVDs , yet that gives you less than 5 % of the data you need . For many customers this is simply not a practical solution for them .
With HIARCS Chess Explorer you have automatic online access to about 1,000Gb of endgame databases with precise information about the game result and outcomes of each move available . This information is perfect , it knows the game result and if a win exists it can give the number of moves to checkmate with perfect play .
In order of obtain this information the " Use Hiarcs server " checkbox must be checked on . This is the default setting .
Whenever you reach a endgame with 6 or fewer pieces on the board HIARCS Chess Explorer will try to determine the outcome of the game for you . The results if available are displayed in the Analysis Explorer pane , here is an example :
This tells you that with best play in the current position Black can win in 38 moves starting with the move
