Big Blind

The big blind is one of the two forced bets (along with the small blind) that create the initial pot. The player in the big blind position posts a full bet before seeing their cards, then acts last preflop but has the disadvantage of being out of position postflop (except against the small blind). In MTTs, stack sizes are measured in big blinds. Saying you have '30 big blinds' means your stack is 30 times the current big blind amount. This standardization allows players to use the same strategic framework regardless of the actual chip denominations. Playing from the big blind requires a unique strategy. Since you have already invested a full bet, you are getting a discount to see the flop. This means your defending range is wider than any other position. Against a button open, for example, the big blind can profitably defend with a very wide range because they only need to call one additional bet to see a flop in a pot they have already partially funded. The big blind is widely considered the least profitable position over time because you are forced to put money in without seeing your cards and you play out of position postflop against most opponents. Minimizing losses from the big blind is a key skill. This means knowing when to fold, when to call, when to check-raise, and when to 3-bet. Skilled players lose less from the BB than recreational players, even though both will lose money on average from this position.
