Moonballs always strike me as a ****** move. But then, I'm still sore from a recent 4.0 SF loss where my opponent beat the crap out of me with a mix of extremely good (i.e., heavy topspin, 1-2 feet inside baseline) moonballs, drop shots, and particularly great serving (he didn't face a single break point). The opponent was a friend of mine, and he never plays like that if we're practicing.
After the match, he said that he had to do it to win the match. I had a game plan too, based on our practice sessions, which was to beat him with consistency since if he doesn't win the point in 2-3 strokes he'll hit the next one long.
Yes, his was the smarter game plan. Yes, I should have adapted my plan when I saw his tactics. Yes, he was serving great and I couldn't get a break point. Yes, he absolutely was the better / smarter player and definitively won the match.
But I still couldn't help myself from calling him a ******* ****** bag under my breath each time he hit a moonball.
