Keep you max bid low and then raise it in the last minute so he doesn't have time to enter multiple bids to get past it. That will of course backfire if he is willing to pay something ridiculous and has his max bid that high. But then at least he gets fucked.

the price is right taught me that when it comes to bidding on ebay, always bid increments, but add a couple cents like 12.03 or 12.53. everyone goes by quarter or 50 cent increments, but add a couple cents and you can win it just by a few cents. works well.
