Yes. Remember these numbers: 8, 27, 47, 67. Here is what they mean.
If the Banker's total is 3, and the Player draws anything except an 8, then Banker draws.
If Banker's total is 4, then the Banker draws against a Player third card of 2 to 7.
If Banker's total is 5, then the Banker draws against a Player third card of 4 to 7.
If Banker's total is 6, then the Banker draws against a Player third card of 6 to 7.
