Players can decide which suits or ranks are less likely to be helpful to opponents by looking at which cards are regularly discarded. This information helps players decide which cards to keep or discard themselves. For example, a player may decide to free up those cards for possible use if thewizard of oz slotsy observe that their opponent routinely discards hearts, which could mean that they are not attempting a heart-based meld. Players can also strategically use discards to give opponents false information about their own intentions. Players can cause confusion and interfere with their opponents' strategies by discarding cards that appear valuable or pertinent to an opponent's possible melds while keeping more important cards in hand. Players must carefully weigh the necessity of protecting their own hand against influencing other players' choices at the table when using this tactic.
