Some context: I'm an intermediate-level men's singles player and I am able to play pretty well against other fairly skilled men. I have a fairly balanced playstyle (relying on a mix of counter-attacks and my own attacks to win points). In a recent tournament, I played against a player whose strategy was to completely tire me out. Their main shots consisted of high serves, long pushes, punch clears, and well-placed blocks. They would never take a "bad" attack that left them open to counter-attacks on a lift, and would opt for a drop or clear instead. In the first set, I kept up with their rallies, but my stamina drained well before theirs and it was very noticeable in the second set when I could barely move my legs. What kind of tactics can I employ against such a player to have a better chance of winning against them (while my stamina is lower)? I understand that improving my stamina is one thing, but tactically, is there something I can do?
