Sorry Guest, I was responding to your question: "Never heard of these terms. Can someone please clarify what is a "checked backward walk" and what is "backward walk turning" ?"
I think we are agreed that BioSimon has a point that there is inconsistency in the use of the term FWT. In his first post BioSimon gives two examples of FWT with 1/8 turn to L, starting from similar positions but ending with very different foot positions. These foot positions have effectively 1/4 body turn to L between them, which is consistent with the lady's action during a hip-twist to fan position.
Laird's introduction of the 'action used' column in his charts was very useful, but I feel it would be more beneficial and less confusing if it is only used when the action is significant. IMHO in many cases, such as the one being discussed, the attribution of an action used is rather artificial.
Out of curiosity I check Laird's 1972 Green Book, which gave more details than later editions. That gives lady's step 2 as "RF fwd and slightly to side to finish RF back and slightly to side." while the man has a leading action "Lead lady to L side by tension in both arms."
For the lady to move fwd at all requires the man's shaping which results in the overall turn of 1/8 L which is common to most basic figures. In the UK at least it is common for beginners to be taught the basic movement and Fan without this 1/8 turn (an ISTD suggestion). As a result, the lady's step 2 does tend to become a sideways or even bwd step, turning.
