To me, any ball I get a full prep and swing at from within 3' of the baseline is a forcing/winner attempt with a good enough percentage of succeding, then it's well worth the try. I"m not a little weak rallyer. I'm a strong hitter who can hit at almost any level, IF I get there in time.
That's the catch....gettting there. I often don't, which allows my opponent to hit another ball, then another, then another.
I need to nip that crap off in the bud, hit my first availible ball as hard and deep and well placed as I can, then go for the followup putaway shot.
You rabbits who don't believe in first strike aggressive tennis should play the way YOU think works for you.
I know, if I play timid and weak, I'll lose worst than playing like a lion.
