The time of change

While playing chess the most complex movement belongs to PAWN, although it can move just one square forward, but it never gets back, it moves one square straight, but when it kills, the straight direction changes to the new path, the weakest part of the play moves one square by one square but when gets to the end of the board then it is a miracle, it can be queen, knight or bishop.

At the right moment of play,the weakest piece of play converts to the strongest, right when it is needed the most.
