Einstellung Effect

Chess players are confronted with a chessboard. Faced with the position of the pieces, most of them recognize a classical move. 

The idea of the classical move leads them to applu it to reach the solution. Very few realize that there is a simpler and more direct move. 

We tend to use known solutions to solve our problems, preventing us from exporing better alternatives.
