There are hints of an even more interesting magic system, but JK is too female to explore it properly.
In Half Blood Prince Harry tries to fight Snape, and Snape just toys with him. He then says something like, "You'll never be able to hit me until you learn to keep your mouth shut and your mind closed."
Snape could actually read Harry's mind to predict his next attack and counter it.
In a high level duel you could imagine both wizards trying to conceal their next move and read their opponent's. Using feints and trying to slip past the other's guard with a spell too unexpected for the other guy to trivially block.
When Voldemort and Dumbledore fight neither of them use basic attack spells. They just keep throwing weird shit at each other hoping the other one won't be able to see it coming and think of a counter to it in time.
