What's the use of a Texas Hold 'em dealer?

The role of bankers is not to bid. The dealer in the game is used to determine the position of the blind. The first player on the dealer's left made a small blind, and the second player on the left made a big blind. The dealer is the person who plays all the games in turn, not the right to bid. In fact, the first betting position is the person to the left of the big blind, which is generally called the gun position. In addition, in offline live-action competitions, if there is no special dealer, the dealer will be responsible for licensing.
