Basic strategy - a playing strategy that is designed to minimize the house edge as much as possible without using techniques such as card counting, shuffle tracking, or dealer tells.
Basic strategy is used as a foundation for card counting, but is also used by many non-counters.
Burn cards - cards that are discarded without being dealt to the players. Cut card - a card that is used to cut the cards after they have been shuffled by the dealer. Double down - to double the initial bet and receive exactly one more card. The option to double is often allowed on the players first two cards only, although some casinos allow doubling after splitting a pair. It is very rare to find games that allow doubling of hands that have more than two cards.
