Doubles partners that won't position themselves properly is my pet peeve. There's numerous types:
1) Hang back Harry - still thinks doubles is a singles game and he can just hit topspin FH's from 3 feet behind the baseline and dictate play
2) Towering over the net Thomas - Never more than a foot from the net, crushes balls often before they cross the net to his side, spends most of the second set yelling "yours" when lob after lob goes over his head.
3) Midcourt Mary - 3.0 ladies doubles player that is used to taking moonballs out of the air from no man's land to the service line and just hangs out there in mixed getting bludgeoned by dipping topspin at her feet
4) Alley Camper Adrian - stands and the junction of the service line and doubles alley and NEVER moves. Complains of a weak net game while failing repeatedly to salvage ankle high volleys.
5) Poaching Peter - doesn't matter the likelihood of a successful poach or how good (or bad) his partners serve is, he always attacks the middle. Gets passed repeatedly down the line, muttering "lucky shot" after every one. Nets one in two diving backhand volleys. Every 4th try, hammers a winner with a fist pump and "c'mon!!"
generally i'll take Poaching Peter any day, all day.
yesterday played dubs.
my partner, Poaching Peter, apologizes for missing 2 volleys... "i'll let those go next time".
i insisted that he remain aggressive, and he'll find his range
i win all my service games pretty easily... often getting 1-2 free ufe points (which i attribute to the returner looking up to see what my net partner is doing).
if my serve is so weak that it's getting pummeled or sent down the alley easily for a winner, i might suggest planned poaches/fakes... so i can get in sync as to when to cover his side.
if partner is missing alot of volleys, i'll suggest that i'm there to back him/her up if they want to let it go... (ie. i will presume every shot is mine,... so they are free to bail out if the ball is too far wide, low, etc...), but i'll still insist they remain aggressive.
most folks don't notice that aggressive net play often leads to unforced errors (but the winners and mistakes are what most folks only remember).
