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.
