User Interface 93 2.1.4.1.8 Search mask – Position Se a rc h m a sk, Posit ion. This allows you to search for positional fragments, including strategic and tactical manoeuvres based on pawn structures and piece constellations. There are three definition boards: The “Look for” board: Here the pieces are set on the squares on which they must be in the positions you are looking for. The “Or” board: This allows you to define fuzzy positional fragments such as “all positions in which piece x is on square a, b or c”. The “Exclude” board: With this you can establish which pieces should not be on specific squares in the positions you are looking for. To put a piece on a square, first select a piece type on the right. A click on the square on the board will put the piece there. Clicking with the right mouse key will insert a piece of the opposite colour. The “joker” symbols on the bottom mean any white and any black man (pieces or pawns). On the Exclude board you can place up to four different pieces on a square. To remove any one of them press Crtl and click it. The same also applies to the Or board. ChessBase 2014
