First the tables: Texas hold’em is played online on tables of 2 to 10 players.
The dealer is the person that deals the cards in a poker game. In Texas hold’em the player that sits on the dealer position is the last to act. In online and casino poker there is a small button below that player that lets everyone know he is the dealer, regarding the fact that the real dealer is not present at the table like in home games.
The blinds in Texas hold’em are two the small blind and the big blind. They are forced bets that have to be made prior to the actual dealing of the cards. The big blind is the first person placed on right to the dealer and the small blind is the bid placed by the person sitted left to the dealer. The big blind is twice as big as the small blind. Their value is set by the organizers of the game and the way the dealers and the blinds change is clockwise.
