Yes, slurs are impossible on the piano, but we try our darnedest to create the illusion of slurring by overlapping notes slightly.
What do slurs mean in piano?
A slur is a symbol in Western musical notation indicating that the notes it embraces are to be played without separation (that is, with legato articulation). A slur is denoted with a curved line generally placed over the notes if the stems point downward, and under them if the stems point upwards.
What's the difference between a slur and a phrase mark?

A slur may be hard to distinguish from a "phrase mark," which looks like a slur but may cover a longer passage and really just indicates that this is one phrase, like a phrase in spoken language.
