DO YOU KNOW WHEN TO TAKE YOUR DOUBLE?

It’s always a hard decision. But you are best off taking it right away if you haven’t played that part of the court before.
So if you miss it you’ll have another chance. If it’s located where you know you know the drift, then wait for your hammer and make two blocks.
Of course you know you shouldn’t take doubles with your hammer unless you really really need the extra score because you may get nothing!
