Having a particular advantage is not always enough to win at chess. Sometimes you need to transform it into a different type of advantage in order to win. Here are some examples:
Relinquishing material for a decisive penetration
White has an outside passed pawn but that alone is not enough to win. But he can simply relinquish it by playing Kd6 in order to penetrate on the other side of the board with his king. This leads to simple win.
Lead in development transformed into strong attack (Morphy against Carl)
A lead in development is a dynamic advantage which evaporates with time if not used. Here Morphy had a lead in development which was quite usual with him! He had chosen to sacrifice a piece in order to convert his development advantage into a strong attack. On the other moving the bishop to d3 or e2 leads to satisfactory game for Black after 10…Nbd7. Here is the whole annotated game.
Transforming a queenside majority into a material advantage (Marshall against Capablanca)
It was Steinitz who considered a queenside majority an advantage due to its potential for creating an outside passed pawn. The example below shows Capablanca’s fine technique in transforming his queenside majority into a material advantage.
