Your game should be structured around many different types of shots (serve, return, loop, push, smash, block) and many different variations of each shot (speed, spin, depth, placement, height).  Most players are very irregular in the types of shots that they use throughout the match, and so these players think that they are being “tricky” or “irregular” throughout their matches.
 
When closely inspected through video analysis, many of these players are truly good at different types of shots BUT very bad at variations for each shot.
