where does the expression cherry picking come from
Cherry picking The term is based on the perceived process of harvesting fruit, such as cherries. The picker would be expected to only select the ripest and healthiest fruits. An observer who only sees the selected fruit may thus wrongly conclude that most, or even all, of the tree's fruit is in a likewise good condition. This can also give a false impression of the quality of the fruit (since it is only a sample and is not a representative sample).
Betting in poker Until the first bet is made each player in turn may "check," which is to not place a bet, or "open," which is to make the first bet. After the first bet each player may "fold," which is to drop out of the hand losing any bets they have already made; "call," which is to match the highest bet so far made; or "raise," which is to increase the previous high bet.
