Neither of these are likely to influence the game, you can't force a draw against someone 500 points stronger, since he will understand the game so much better than you.
Play your best from start to finish, play it for a win, as you would against any other opponent, and if you lose, then so be it, atleast you enjoyed it, and hopefully learned from it.
I'm in my first tournament this week and I have been lucky enough to be paired with the clubs strongest player with me playing black. I estimate that he is a good 500 points higher then me. As such do you think I should play for the win and learn from the loss. Or play for a draw and learn for the loss.
Thanks,
