When your opponent smashes a fantastic shot cross-court that you reach for on the run;
Then they smash it into the other corner expecting a winner while you're still in the corner, you run it down and stretch to just slice it back with your backhand;
They approach the net and hit a sure winner volley which you somehow manage to pop up deep as it's going past you; t
They run back to the baseline to cover it and take a big swing going for broke and it hits the tape on their side with a thwack falling into their court for your point (<--- this is the most satisfying shot);
they turn purple, scream, and swear (maybe even throw/smash their racket) knowing that they hit three winners yet still couldn't win the point as they realize they are screwed for the rest of the match as you both know you've mentally broken them.
