My adjustment was to treat the 2nd serve return as an approach shot, which worked out better, but at that point I wasn't executing well anymore.
The other tactic which did work well was drawing him to the net. In this case should I have tried drawing him to the net like 80% of the time?
Looking back, my mental state was strange, hard to describe. Strangely enough, I was the one feeling rushed and not executing my patterns.
