Opponent Preparation
The Opponent Preparation report lets you analyse any opponent you have played, studying their opening tendencies, strongest lines, and where they deviate from their own established book.
Accessing the report
Section titled “Accessing the report”Navigate to Reports in the left sidebar. Type an opponent’s name into the search field — autocomplete suggests names from your game library. Select the opponent to generate the report.
You can also reach the report from the Games page: right-click any game and choose Prepare for opponent.
Report sections
Section titled “Report sections”Record summary
Section titled “Record summary”The top of the report shows your overall record against this opponent: wins, draws, and losses, total games, and a date range.
Colour breakdown
Section titled “Colour breakdown”The opening tendency section is split into White (games where the opponent played White) and Black (games where the opponent played Black), each showing:
- Most frequent openings by ECO code and name
- W/D/L percentage for each opening system
- Number of games
This gives you a quick picture of what openings to expect and how well the opponent performs in them.
Strongest lines
Section titled “Strongest lines”The strongest lines tier ranks the opponent’s most successful opening systems by result rate. These are the systems where they score best — prioritise preparing against these.
Each line shows the opening moves, ECO label, result rate, and game count.
Deviations
Section titled “Deviations”The deviations tier shows the exact positions where the opponent deviated from their own established book — positions they have reached multiple times and then played inconsistent moves. These are your opportunities: if you can steer the game there, the opponent is likely to be less prepared.
Batch analysis
Section titled “Batch analysis”The Analyse all games button at the top of the report runs batch engine analysis across every game against this opponent that has not yet been analysed. This populates accuracy data and makes blunder-based statistics available.
Batch analysis is not required to view the opening tendency breakdown, which is based on move sequences only.
Export as PGN
Section titled “Export as PGN”The Export PGN button generates a PGN file containing all the opponent’s games and opening lines, annotated with W/D/L statistics as comments. The file can be opened in ChessBase, SCID, or any other chess tool for offline study.
