With a two-card total of 5, the Banker draws whenever the Player stands on 6 or 7, and when the Player draws a third card valued 4, 5, 6, or 7. The Banker stands on 5 when the Player's third card is 0, 1, 2, 3, 8, or 9.
A two-card 5 is the highest Banker total that draws when the Player stands on 6 or 7 (since a standing Player holds at least 6, forcing Banker 5 to draw to compete). However, when the Player draws a third card of 0, 1, 2, 3, 8, or 9, the Player's three-card total often lands below 5, making it mathematically superior for Banker 5 to stand rather than risk drawing a 5, 6, 7, 8, or 9.
Dealers check two branches on Banker 5: (1) Did the Player stand on a two-card 6 or 7? If yes, Banker 5 draws. (2) Did the Player draw a third card? If yes, Banker 5 draws only if that third card is a 4, 5, 6, or 7.
