The player immediately clockwise from the small blind posts the 'big blind', which is typically twice the size of the small blind (blinds can vary depending on the stakes and betting structure being played).

In Hold'em, a marker called ‘the button’ or ‘the dealer button’ indicates which player is the dealer for the current game.
