Even after 45+ years of pool playing, I continue to be amazed at the fragility of "dead stroke" and the factors that can blow it up. A pool player can go from a high confidence ball making machine to a timid, low confidence, ball hanging machine in a matter of minutes, literally from one game of pool to the next. The other day I was playiing one-pocket with a guy whom I have played often and who plays about my speed. In the first two games we played, I made no real errors and missed no shots. The game felt easy as I coasted to an 8 to minus 1 win and an 8-0 win. The third game was going along about like the first two, when I mentally "let up" and quit really bearing down on my shots. Maybe I wanted to prolong the session and feared that my opponent might pull up if he got too frustrated, but for what ever reason, I just started playing with a "casual" attitude and missed a couple of shots that I should have made. Suddenly, the shots no longer looked easy. When I tried to recapture my earlier level of performance, I found myself getting tense and coming up off of shots. My opponent's level of play jumped way up and I lost 4-5 games in a row. Most of you have had similar experiences where your level of play dropped dramatically for one reason or another and you found yourself facing relatively easy run outs with almost no confidence in your abiility to run balls. It would be like a weight lifter who could normally press 250 pounds with ease suddenly found himself unable to get 100 pounds off his chest. While there may be many, many factors that can lead to such a sudden decrease in your level of play, the experience I had highlights one such factor; mentally "letting up" during a match. Anyone able to offer some other factors that can drop you right out of "dead stroke?"
