Based on the limit of the poker game the player to the left of the dealer's button (small blind) and the player two to the left of the dealer (big blind) are required to place mandatory bets in the pot before cards are dealt (Small blind has to put half of the big blinds amount). These bets count toward the first round of betting. So if the pot is not raised preflop, small lind will only have to put half a bet to call and big blind has the option of raising or just checking.
In a poker tournament, blinds go up gradually. This is to ensure that the tournament finishes on a timely manner. (the higher the blinds get the more players tend to get eliminated).
Blinds usually go up after pre-determined periods of time. (for example every 15 or 20 minutes). Two main factors determine blind structure of the game:
Starting chip amount
How long you want the tournament to last.
Issues concerning the small and big blinds are generally much more important in Limit poker than in No Limit games, but no matter what the game structure, the blind bets are extremely important to consider when you make them and also when someone else is making them.
1) Forced bets in community card games similar the use of antes, but normally
only required of two players rather than all players at the table
2) Small Blind: the smaller of two forced bets, usually 1/2 the minimum opening bet
3) Big Blind: the larger of two forced bets, usually equal to the minimum opening bet
4) Stealing the Blinds : make a raise on the opening betting round with the goal
of winning the blind bets without any further action on the hand
5) Betting blind: betting without taking the option to look at the next card

Straddle - Straddling
Killing the pot from first position; adding an extra, double-sized blind
when you are first to act before the flop in Holdem,
allowing you to be last to act before the flop
Kill - Kill Pots
1) An extra, larger blind that increases the stakes for the following hand;
sometimes kills are required by the winning of a previous pot,
sometimes they are an optional choice
2) Full Kill: when the kill blind doubles the normal big blind,
thus making a 10/20 game now a 20/40 game
2) Half Kill: when the kill blind is half again as large as the normal big blind,
thus making a 10/20 game a 15/30 game.
