Investigators with the Nevada Gaming Control Board have accused a Las Vegas baccarat dealer of cheating to benefit a player and receive tips, court documents said.

In June 2020, a gaming investigator received a complaint from The STRAT Hotel & Casino about the dealer, Ying Yu, and a potential incident of dumping.

“Dumping a game, as referred to in this case, is a method used by a dealer that is outside the normal procedures and rules of the game to fraudulently benefit the player,” the investigator wrote in court documents. “The method usually involves overpayment from the dealer, dealers switching wagers from losing to winning outcomes, or some type of sign to a player to effect the outcome in the players’ favor.”
