Personally, I think playing with a much weaker or much stronger is a waste of time for both. You should play with people that are on your "spectrum". The problem with a much weaker player is that either you play noramlly, they can target him and you lose (and youre almost not playing, even more frustrating), or you adapt your strategy and do some kind of mixed stuff but youre not playing doubles anymore.
There is only so much you can do if your partner is too weak. Just don't invest too much feelings in the game! lol
