Yes, get him out of his opening preparation!! Prepare a 1.b4 or 1.b3 system against him and get the game complicated!
I also had such an opponent in my chess club. Either he goes into Berlin strucures or else he tries to swap queens as soon as possible. Lately I have two wins against him by getting him into unknown territory. I used king's gambit against him and all his carefull preparation went out of the window and now he has to defend :).
wow! This topic really hits the spot. I love draws, I have a boring repertoire and I prefer very long games.
Well I think you have to prepare a lot against him. Choose sharp openings, avoid early endgames and know what pawn structures he prefers and exploit it. Or be an endgame specialist yourself
You might try getting him mad with a few select insults. 
Seriously though, if you're higher rated than him, can't you only allow trades when it's advantageous for you?
Playing black against drawish players is tough. We have to manage our expectations. If we can draw with black and win with white, we can eventually become world champion !
you dont
What is the time control?
As you said the guy might actually be better player than you. Maybe his chess is to play solid, defensive style and to block all attacks and play positional game. I think it's fine. Don't care about his rating, care about the game and try to improve and extract good things about games vs him.
There is one particular player at my chess club who only ever plays for a draw when I play him, even in friendly games. He's lower rated than me, but he plays such boring, safe openings and defends so well it's very hard to get a win off of him.
He's a good player, so I think that the reason that he is so low rated is because he draws so many games and wins so few. When I draw to him in rated games, I end up losing rating points due to being higher rated than him! It's quite frustrating, as I'm sure you can imagine!
Is there a way to play against someone like this?
