Honestly I did not see very much strategy in the 2 quarter finals last night.
Almagro & Berdych:
* hit a huge serve and put away the weak returns.
* backhand slice ~ 5% of the time (when in trouble or on the run)
* rip every ball for a winner or hit to a position where the opponent does not seem to be standing.
* or trade topspin groundies till the other guy misses.
I did not see directional's being employed.
I did not see a single surprise first serve kicker wide + volley put away.
Forehand approach shots were hit with topspin (ala Roddick).
Very few approaches on short balls to the backhand side.
Few Backhand approaches were short slices that sat up.
So, I gotta go with Suresh on this one.
