When defending smashes in singles, I stand with my racket foot out and it is simple and easy. But for doubles my coach teaches me to stand with my non-racket leg out and just a thumb backhand grip all the way. When the opponent smashes im supposed to move in with my racket leg and just block the shuttle. Seems rather easy in training but during a real match I somehow revert back to my normal way and stand with my racket leg out. This is quite good as I'm able to drive back smashes but the weakness of this is the opponent doing cross court smashes into my forehand. How do you guys stand?
