Nutzen vs benutzen
There is a distinction between nutzen and benutzen. The former is used with opportunities or options, the latter is used with means or instruments. Sometimes this is just a matter of aspect. For example, “He uses the computer” can be phrased as Er benutzt den Computer (mere mechanical sense), or Er nutzt den Computer (implying that the computer is, in whatever way, an opportunity).
Basically "make use of" vs. "use".
