I don't mind THAT much, so long as I remember I'm playing a lefty. I regularly play with two lefties right now, about once a week or two, and both have pretty weak backhands. They can't pass of it and I reckon if I played a serious match against them I would just loop forehands crosscourt to their backhands all day long. One guy can't handle slices to his forehand. Actually, it's a bit of sample bias going on I guess because these two particular lefties have exploitable games. I sort of think the advantage of being left handed is overstated in general.
