And to answer your question. YES, I have said all of the above in my sordid career. My favorite response when entering a new room and being asked by the houseman how I played, was "I can play a little".
Oh and one other line I liked to gain the upper hand. "If you like the game, you can empty out". It was always important to have a psychological edge when playing someone who could play. If they wanted to play for ten a game, I would ask to bet twenty. Even if we started out for ten, they were thinking about this.
Here's a couple of other good moves I liked, to intimidate a new opponent. Please don't tell anyone. Okay? Back in the day, I was in action and playing EVERY day, so I stayed in stroke. I would go into a new room looking for a certain player I heard about or just cruising the room looking for a game. More often then not, the player would be warming up already on his favorite table. After we made the game, I would let him warm up all he wanted, watching him to gauge the speed of the table, and to see where the rolls were. When he asked me if I wanted to hit some balls, I'd say sure. I would place a long straight-in shot on the table, carefully take aim, and fire it in. I rarely missed this shot. Then I would say I'm ready. Do you have any idea what this did to his confidence? I just took a one shot warm up. This was my routine when playing in a new room. I knew I would be wired in on the table after 15-20 minutes of play anyway.
One other move I made in the early stages of a match (remember I played in the days of "roll out" pool). When my opponent pushed out for a tough shot that he thought I would pass on, I got down and fired at it anyway. If I made it, he might start getting a little weak, and if I missed it he would wonder what he was up against. I can think of several times that moves like this helped me get the best of a marginally better player.
