Notes:
- 
Brace Thru is a sex-dependent call.  After the Right Pull By,
    each couple must consist of one Boy and one Girl.  
    Brace Thru can not be done if any Couple consists of same-sex dancers.
- 
The U-Turn Back is done by turning toward each other.  
    This is important in case the caller adds a Roll.
- 
Brace Thru is a variation of Right & Left Thru.  
    The Courtesy Turn action is either done normally (as a Couple), 
    or individually (i.e., U-Turn Back).  Whether you do a Courtesy Turn 
    or U-Turn Back depends respectively on whether you are a Normal or 
    a Half-Sashayed Couple.
- 
Brace Thru is useful for callers since it resolves 
    sex-problems within the square.  After a Brace Thru, 
    everyone ends in normal Facing Couples (Boy on Left, Girl on Right).
- 
In 2012, Callerlab renamed Half Breed Thru to Brace Thru.
- 
Historical note: The original definition of Half Breed Thru had 
    a Pass Thru instead of a Right Pull By.
