Where is the weak spots for people who use shakehand

I once see a picture displaying the weak spots where most shakehand are really quite weak in, but i forget where did i save the pic.

i remember it says that the middle are the weak spots as shakehanders need to decide where to use backhand or forehand, but i remember that's more than the middle.

I'm a penholder who only use the forehand, is there any weak spots that oppenent will aim for?

Hi,

I think the spot you are talking about for shakehanders is their crossover point.  This is teh position that they change from forehand to backhand.  This is usually close to their right hip, for a right hander.

For the penholder that uses forehands a lot, I think the spot would then be their backhand side.  They may also play wide to your forehand and then follow this up with a ball into the backhand.
