Rematch against a cheater...

[Sherlock]

One suggestion I've heard that would be interesting to try and funny to see it work, would be on the next point to call out the score as if you had won the point. Don't even argue about the line call, just pretend he didn't even make it.

Say it's 15-15 and he made the bad call, then you say, quite loudly "30-15" before your next serve, while exaggerating eye contact with him. If he gets upset about it, say something nonchalant like, "Oh, well it was 15-15 and I just hit that winner, so now it's 30-15".

It might not turn out well, but it would be fun to try sometime

i would just dropshot and lob on every single point. that would drive him crazy. oh yea... and you have to laugh after each point so he can hear u.

I had to play a known cheater in the second round of a club tournament. It's not fun. But I would suggest having someone watch your match. This might put pressure on him/her to stop cheating. It's just no fun.

I don't see why there's any need to change the way the OP plays. If he's already winning 1 and 3 without even trying particularly hard, then there's a massive gulf in abilities between them.

Just go out there and play your normal game.

I played a doouche like this just a couple of months ago, who called practically every serve I hit on the line, 'long'.

As for making an issue of it before or during the game, it depends on whether you think this is going to disrupt your or his game more. If I get slightly annoyed, I become more focused. If I get too angry, I find that it disrupts my own game. If you think you're the type that can make a point about it without any of the possible consequences disrupting your rhythm, then call him on it when it happens.

Personally, if I had so much of a game advantage over him, I would tell him afterwards that made a number of bad calls, 'you do realise the edges of the lines are in?' etc.

Sorry I thought you meant you were a pro playing Nadal again.

I don't get why you're even playing with him, if you don't enjoy it, the difference between your skill levels is obviously huge.

If you HAVE to play him for some reason, let him know each time he makes a bad call. If it's more than a few times, or very obvious, talk to him and let him know that if he's not interested in playing an honest and friendly game, you'll stop the match and bring up this issue with league organizers.

It's always best to try to politely talk it out, perhaps he's just not seeing well. If that doesn't work, then the best solution is to try to avoid playing him. You might be able to get an exemption from the league, it's in their interest to avoid these type of conflicts anyway.
