About

      

        This is a prototype of an upcoming training tool inspired by some Lichess comments. 
      

      
Instructions

      

        The yellow message bar will tell you which pieces you have to find. An undefended
        piece is a piece that is NOT defended regardless whether it is attacked or not. 
        A hanging piece is a piece that is NOT defended AND attacked. You have to view 
        it from both perspectives (black and white). If there are for example two rooks on an open 
        file (one from black, one from white) and they attack each other then BOTH of those are under
        attack. pseudodefended pieces are pieces that are defended but where the attacker
        is of lower value than the defended piece. If a knight is defended by a piece but attacked by 
        a pawn then the knight is considered pseudodefended. An attacked piece is a piece that is 
        attacked regardless if it is defended or not. Important: The king never counts as a 
        an (pseudo)undefended piece and also never as a hanging piece and also never as a defended piece. 
        An pseudodefended piece technically counts as a defended piece because it is defended (just not 
        good enough but it is defended). If you are asked to find squares the king can or can not move 
        to then this is from the perspective of the king currently in check. The king not in check is to be 
        ignored in that case. A pinned piece is a piece that can not move. 
      

      

        If you click the restart button it will reset the stats, start a new puzzle and immediately
        measure time. The focus will immediately shift to the board. Time ticks!
      


      
Motivation

      

        Beginners often blunder pieces. They are usually told to practice tactics when they ask how 
        to get better but it is my opinion that the first step must be to have a rough understanding
        of what's going on on the board and only then it makes sense to progress to tactics. This tool 
        trains exactly this. It doesn't ask for tactics it just simply asks whether you understand which 
        pieces are defended, hanging and the like. You don't have to plan multiple 
        moves ahead and calculate lines. Therefore - in theory - it should exactly train 
        beginners to see the board better.
