Signal: Slide cards under chips (in handheld games); wave hand horizontally (in games dealt face-up). For late surrender, however, while it is tempting to opt for surrender on any hand which will probably lose, the correct strategy is to only surrender on the very worst hands, because having even a one-in-four chance of winning the full bet is better than losing half the bet and pushing the other half, as entailed by surrendering.

Hand signals help the " eye in the sky" make a video recording of the table, which resolves disputes and identifies dealer mistakes. It is also used to protect the casino against dealers who steal chips or players who cheat. Recordings can also identify advantage players. When a player's hand signal disagrees with their words, the hand signal takes precedence. If you're fairly sure that your hand will beat the dealer's, you can double your original bet.

If the dealer doesn't have a natural, he hits (takes more cards) or stands depending on the value of the hand. Contrary to the player, though, the dealer's action is completely dictated by the rules. The dealer must hit if the value of the hand is lower than 17, otherwise the dealer will stand. Surrender: Forfeit half the bet and end the hand immediately.
