Scare Card ( poker )

1) A card that when it appears makes a better hand more likely. 2) In hold'em, a third suited card on the river is a scare card, because it makes a flush possible. If you're pretty sure your opponent paired a king on the flop, an ace on the turn is a scare card. Scare cards will often make it difficult for the best hand to bet, and offer an opportunity for bluffing. Obviously such cards are scarier in pot-limit or no-limit games.
