8.4.3.1 Checker play statistics

This section provides a summary of the checker play statistics. The following information is available

  1. Total moves: The total number of moves in the match.
  2. Unforced moves: The number of unforced moves, i.e., all checker play decisions which had more than one legal move.
  3. Moves marked xxx: The number of moves marked very good, very bad etc. The analysis will mark moves very bad, bad etc. based on the threshold you've defined in the analysis settings. GNU Backgammon can currently not automatically mark moves, e.g., good, but you can mark moves good yourself.
  4. Error rate (total): The first number is the total amount of normalized equity that the player gave up during this game or match. The number in parenthesis is the un-normalized counterpart; for money play the all errors are multiplied with the value of the cube, and for match play the total match winning chance given up by the player is reported.
  5. Error rate (per move): The error rate per move is the total error rate divided by the number of unforced moves. Note that is different from Snowie 4 that defines the error rate per move as the total error rate divided by the total number of moves for both players, i.e., the sum of total moves for both players. In general, your error rate per move will be lower in Snowie than in GNU Backgammon.
  6. Checker play rating: GNU Backgammon will assign a rating for your checker play ranging from Awful! to Supernatural. See the description for the overall rating below.
