Kim got a buy her second match. I admit I was very rattled playing Sheri, she plays the perfect pace to throw me off, I am a very fast player normally, and I do play better usually than I did against her. I would not gamble with anyone that plays that slow ever. At least I calmed down the last two racks and won seven to five to move forward to the next round. There is a of of money in this tournament, the most I have ever played for.
I watched over half of the match out of curiosity. I won't comment a bunch on the level of play because I've learned that for me anything but the highest level of play is kind of hard to watch and I trust you know your game and know you weren't playing at a high level.
But about the pace of play. In my opinion the pace of your opponent was barely slower than average and nowhere near a level that you can allow to throw off your game. Yes she does an odd thing repositioning both chalk cubes as if they are chess pieces but people do far more distracting things with chalk.
Think about the 5 or 6 really easy shots where you missed a shot you should never miss or left your cue ball way differently than you planned. Maybe learn from Sheri...when a ball is right next to the pocket, walk down an take a look at it. You can't tell from the far end if it's frozen to the rail or a quarter inch off and it makes a big difference to both picketing the ball and getting position for the next ball. So yes, Sheri is a deliberate player but at times you maybe played too quickly to the point of even getting sloppy.
Free advice worth every penny. I've enjoyed following your journey, good luck as it continues.
