BD: Blind DefenseWhen a player is in one of the blinds and the pot is raised pre-flop, BD is the percentage of the time they call or re-raised. The BD statistics can be broken down by the number of other players in the pot, the number of raises, and by position (Small Blind versus Big Blind). Blind defense is one of the most dynamic aspects of pre-flop play, requiring substantial adjustments to your strategy depending on your opponents. When you are the Cutoff or the Button and it's folded to you before the flop, you may raise to attempt to get the blinds to fold. This is called “stealing the blinds”. When the players in the blinds have a low BD, you can attempt to steal the blinds with a very wide variety of hands. On the other hand, if they have a high BD, then you tighten up by raising with hands you'd be willing to play when they call. When you're in the blinds, you will want pay attention to your opponents RFI to see how often they're trying to make a steal. BD per_hand: true
