I was playing a cheap set. I tend to stand up and hold my cue when not shooting. This allows me to move away from an opponents line of sight and holding the cue is just a habit. I tend to shoot and play fast therefore I like holding the cue. In this instance, I placed my cue down when my opponent was on the 8 ball in a 9 ball game. It looked liked an easy shot and I was preparing to rack, therefore, I placed my cue down. He made the ball but got terrible position. Seeing that, I picked my leaning cue up. I was away from his line of sight and was anticipating the opportunity to shoot. Keep in mind my body is still the entire time, and I only picked/lay my cue after his shot. He was a gentleman and told me after the set, what I did was a shark move. I had no sharking intentions as I just enjoy playing. I figured as I was not in his line of sight what I do doesn't matter. Am I in the wrong? I think I play fair and have gambled for a long time in pool. This is the first time I was told that what I did was considered a shark move.
