"Anonymous. Put an extra slow into a Change of Direction after a Reverse Turn or a Natural in the Foxtrot you will get run over with that extra slow."
What astounding idiocy! You should not dance a change of direction unless you own the corner - if someone can get behind you, you have misplaced the figure. If you own the corner, no one else may enter it.
"Change the timing after the Reverse to q q s for the Change of Direction and you will live on."
Again, gross ignorance. Do not change the timing of moving figures, change the timing of stationary osition-development ones instead. Especialy if you need to comply with a limited list of legal steps with fixed mandatory timing for the moving figures.

Of course, you have to actually understand the reason behind was what written. Until you do, please stop making ignorant and unwise recommendations!
