It is one of the unavoidable facts of (chess) life that sometimes you get paired against people you don't want to be paired against. I'm not talking about me v Kasparov or even Kramnik v Topalov, but in the case of many swisses, members of your own family.
Of course this is due to the faceless pairing programs used by arbiters these days (one press of the button and the draw is done), and under the FIDE Swiss Pairing Rules we don't change such pairings. But annoying as this is, it can be even more annoying when paired against, say, your brother, and he doesn't even play nice.
