you're richer keep changing in short time.... 

+ 1.5l mineral botol water

yonex bag less than RM100 can do any of that

If u feel bullied, then best way is...
Take the racket, put in the bag and go back sleep.
haha... just kidding la.
well, if he play lots of baseline shots, u r weak at it, then probably u give him more drop shots or drives.

well too many drop shots then ur opponent would always prepare infront and u are pretty much dead.. try to jump and push the ball down?

if opponent lob to baseline, just lob back only..... unless u have a clear nice smash or drop...
sometimes, dun force urself to drop or smash if the shuttle or ur position is not good enough.
For single, always be patience and wait for the chance.

if it's a drive or push toward baseline, counter back with drive to the net and recovery back your position to the center of the court.
can drive cross court or straight drive. If your opponent already wait at front court, then no choice to clear and lob back to baseline, at his backhand side...

I hate to play single, too many stamina and patience...
all my shot returns are for double games, so if i play single, sure KO..
