Index tables are far more important in single-deck games than in multi-deck games. Unfortunately, the count is less accurate than it could be in single-deck games because you do not get to see the other players’ hands before making your playing decisions. Counting by Inference refers to methods of estimating the count of cards in face down hands by the actions of the other players. For example, if the player hits against a low upcard, assume he has two small cards and up your count.
