Position-Analyser

Analyse Position Window

The Position-Analyser is an extra tool which can be started from the main window of the chess GUI. It allows to analyse the position using some properties shown in the chess programming website (CPE). It consists of the Board displaying the current position and the several properties of the position with the:

  • Attacked pieces

  • Attacking pieces

  • Bad bishops, i.e. bishops whose mobility is restricted by own pawns

  • Blocked pawns, i.e. pawns blocked by a pawn of opposite color

  • Controlled central squares, i.e. control over the center squares (E4, E5, D4, D5)

  • Fiancettoed bishops, i.e. bishops on knight pawn squares

  • Hanging pieces, i.e. pieces being undefended and attacked

  • Isolated pawns, i.e. pawns without supporting pawns in the adjacent files

  • Passed pawns, i.e. pawns which cannot be attacked by pawns of opposite color anymore

  • Pinned pieces, i.e. pieces required at the current square to protect the king

  • Reachable Squares, is an indicator of the piece mobility

  • Stacked pawns, i.e. multiple pawns on a single file

  • Supported pawns, i.e. pawns protected by pawns in the adjacent files

  • Trapped pieces, i.e. pieces that cannot move anymore

  • Undefended pieces, i.e. pieces which are not defended irrespective whether they are attacked

By selecting a color for a property, the corresponding pieces are highlighted on the board. The highlight color

  • green for positive properties

  • yellow for neutral properties

  • red for negative properties

indicates the valuation of the position.
