Use this tab to search for material distribution.
Number of pieces
You can specify what material should be on the board. For each white or black piece you can set the minimum and maximum numbers that must appear on the board.
Select Any Pieces to switch on all pieces without having to do this manually for each.
Select No pieces to switch off all pieces without having to do this manually for each.
If the range for white men is set at “3–4” only positions with at least three and at most four white men are retrieved. "1–1" pieces means that exactly one piece of that kind must be present. If you set the range for white kings and black kings at “0-0”, positions with kings will not be retrieved.
Difference
When you switch Difference on the values given for black have a different meaning. They denote the difference in material value between white and black.
Equal pieces
Check Equal pieces of you only want positions where white and black has the same number of pieces.
Stable
During a sequence of captures it is possible that the game position will satisfy the piece configuration you are looking for. But the piece configuration may not be there after playing the capturing moves. Stable means that in the found positions the color to move cannot capture a piece. This check can slow down the search significantly.
Tempo difference
You can use tempo difference to specify the minimum and maximum tempo difference that is allowed in the positions you are looking for. If you specify the tempo difference, the program will only select positions without kings and with the same number of white and black men.
Length
Length refers to the minimum number of consecutive ply (half-moves) the material distribution must be on the board.
Reset
Clears the material data.
