erm...no....rule #2 per op
with the example "yes" which is what i followed with "sailor". i never passed a letter that was previously used. started with "s" and per rule #2 went back in from "a" and finished spelling the word. an illegal maneuver is explained with rule #4...start on "s" go thru "a" to get to "e" then you're stuck because you can't cross "s" a second time to get to "a" and you can't go backwards to get to "a".
