Djarvik think I played the game too dropshots.
My opinion:
Dropshots is a strategic blow against someone good.
Against some players just do not play dropshots because they can handle it expires and give point. Most players DROPSHOT return! Therefore dropshost sometimes good, sometimes bad.
Djarvik has a specific style of play. He is many meters behind the baseline and DROPSHOT often can not run down. Must run away. And he has a slow response. The baseline but is solid.
I know that when I will get dropshots point. Almost always! How often can I use it and get the item for free?
I think that in this case the error is even opponents. Opponent should adapt to play closer to the baseline and then eliminate this weapon. Opponent but failed to adapt.
The game then was very special. I played constantly accelerating and normal shots, but I knew that because of slow reaction djarvik, I always give dropshots and get a point.

I'm still wondering: Can I give dropshots and get a point, or not yet?
It soon? It is too late? Should I hide the blow to important moments (breakpoinst). When I play dropshost during important moments, then it's not abuse? Use dropshost is often unnecessary because it would then be unfair to use dropshots at breakpoints? (Dropshost = point for me.)
According to me this is also error opponent. He reacts if time can defend.
I think it is not so hard to return when ready dropshots tactics.
Many players dropshost always runs out, because they react.
I can also say: I can not respond to top spin. You do not play topspin.

Dropshost How much is a lot? 1 per gem? 5 per set? 7 for the set?
I lost the match. Because I wanted to play too dropshots. I was afraid that it would be unfair. I do not want to play fair. Although I think I've played much in the 1st set (which I won thanks dropshots).
I played dropshost = 8-10 in first set (+ -1 in game). In the other sets I played less. Number dropshots fact was crucial to who wins. I did not know what it is.
I ask the advice of more experienced players. As with dropshost be fair?
