I would like to emphasize that depending on how a clump of cards is comprised would not require a large number of cards to significantly alter house edges. During the second month of business and beyond at the MGM Grand in Springfield Mass I started seeing odd things happening much to frequently. On ASM's games many clumps of ten value cards anywhere from ten to fourteen cards following each other, were happening too frequently. On other shoes me splitting aces four times way, way to often, and seeing other players doing the same thing and I might add filling those aces rarely with ten value cards regardless of count. I also would like to point out I saw a few ploppies who were deliberately splitting and re splitting tens and win most of their hands, because I think they recognized the clumps that were taking place.
Two years ago I would not believe something like cheating could possibly occur in large casino chains. However with all the new technology advancements who knows what is possible. The industry itself would likely say as long as there is a cut taking place by a patron nothing is wrong.
