As far as doing things to make him feel bad, like making a big deal out of going out with the other guys after the match and excluding him--I wouldn't do that either. That would bring you down to his level. Since you say that you have exhausted your recourse in talking to him and you don't want to bag the game altogether, you're better off being yourself. I'm actually surprised that you got so much advise to that effect--that doesn't sound like the gentlemanly conduct that we encourage around here.
Hope that venting on here makes you feel better!
Admittedly, taking that kind of action would be taking the low road as would starting any kind of a physical fight - not very gentlemanly, but just sucking it up is easier said than done. You told this guy directly and in a gentlemanly way that his behavior was ruining the fun for the rest of you, yet he continues, apparently knowing there's not much you can do about it. In a way, this makes him a bully. Even if it is just one morning a week, giving up anything to a bully is no less frustrating to us as adults as it was when we were kids. If he doesn't care that he's alienating himself from a good group of guys, then you're better off letting it go - doing the right thing, even if it's easier said than done, separates the kids from the adults, and makes you the better man. But there's nothing wrong with venting, and it can be fun to fantasize about taking that low road. Sorry, I didn't mean get so long winded again. I guess I'm venting a little bit myself. I sympathisize with anyone dealing with any kind of bullying, as it looks like you are.
Solution #3: start bringing a book on a famous serial killer to the court/reference a new book on serial killers, and explain that you're really sympathetic because the guy just couldn't take it anymore. Let everyone else in on the joke, and just continue to make the guy feel uncomfortable (make up details about how said serial killer played tennis with an obnoxious guy or something less conspicuous).
While that is funny please be careful if you ever try to employ this type of tactic. In our PC world and society something like that might be considered a terroristic threat.
After the tenis match go out for a cocktail bring in a hired escort to luv up on him in the bar take photos and send to wife. He'll be too busy with the divorce lawyers to bother you anymore! LOL
He who gets mad first, loses. Keep your cool, laugh at him. Don't let him get to you, because if you do, he wins (and that's what he's really after).
Some guys are just jerks, but it's usually an ego thing and the only way to stop them is to short circuit the ego.
If you didn't actually own the book and never had anything written down, wouldn't it be impossible to prove?
Beating him to death with your rackets might also be a good idea, too.
