Poker blinds are mandatory bets that are placed into the pot before any cards are dealt.
Blinds help drive the action forward and prevent players from simply folding until they are dealt premium cards.
The small blind is the player immediately to the left of the dealer button and the big blind is the player to the immediate left of the small blind.
It is possible for a player to take two big blinds in a row, e.g. if one player had just played the big blind at a table which then broke down, the player could then be seated at the big blind position on the new table.
