Blinds are bets that players are forced to make before the cards have even been dealt and hence the name since they are like a blind bet. Blinds were originally introduced to the game in an attempt to try and stop players from being too conservative or folding their hand without even placing a bet. There’s usually a small blind (placed by the player left of the dealer button) and a big blind (placed by the person on left of the player who placed the small blind). In a poker tournament it’s common for the blinds to gradually increase at intervals and has the effect that as players are eliminated, the remaining players are left with more and more chips.
