The names of players at the poker tables are hidden in order to protect them from prohibited practices (such as “mining” and “bumhunting”). When choosing a poker table, you won’t see the names of your opponents until you play from the big blind.
Player protection is valid for all types of cash games, it cannot be disabled. After opening the table for the first time, you will see an information window about this rule.
The exception is the Rail Table Ticket.
