The Analyse game dialog enables you to set up the current selected engine to analyse a game. You can set the following information to control how the game is analysed and annotated:
- Average time per move - this is a guideline time the engine uses per move, over the course of the game the engine tries to average this time per move. However the engine has the freedom to spend more time on difficult moves and less time on easy moves.
- Analysis format - you can select Score only or Score and engine name. Both will insert the evaluation and depth of search but the engine name is only added to the Game Notation if the engine name format is selected.
- Annotating engine - you can adjust the annotating engine name to a shorter form which you prefer.
- 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.
