If your partner can't volley find a new one.
The ladies get broken a lot, relax and focus on grabbing a game here and there.
Slant and L formation:
"L" formation: The only place your partner has responsibility for is her service box and the doubles alley. Hence "L"
"Slant" formation: You partner has rights to her service box and 30-40% of the baseline. Hence "\"
I rarely use "L" unless my pard is a granny with a nice net game and zero mobility.
If you have a good overhead take them all. The best 3.5 females on an 8.0 team have a 6th sense for when to duck and cover.
Another way to win, figure out what shot is her best and try to set it up. I happen to be really good at this which is why I like a pard with a very unbalanced game.
