A player after receiving two cards in the beginning has options of “hit”, “split”, “stand” or “double down”. Each of these options generally has some signal of hand.
While opting for a hit one is required to take a card from the one dealing. The signal is to scrape cards against the table surface. For a face up just tap on the table. When going for a stand do not take any more cards from the dealer. To signal the same just hold the cards under the chin and for a face up wave the cards horizontally.
