Imagine this: A player, as white, starts with a gambit, sacrificing a pawn for a development advantage. He goes on to win the sacrificed pawn back, but his bishop is undeveloped still, and his pieces are forced into passivity after black opens up the position. White loses the exchange, and, later, the game. This is one such example.
