Two players were nabbed - at least the circumstantial evidence is convincing (and interesting) - at the World Open in Philadelphia last month. One had an earpiece designed for wireless communication. The other had his winning run against top-ranked players examined, and it was found that his moves perfectly matched those from a popular computer program. When challenged, he spent most of an hour in a bathroom stall. Doing what I wonder? Whatever he did, it was enough to end his tournament run.
