your DR first centric thinking lets you forget that you can leave the FR square floating R' away ZZ style
Read the post above yours again... do you get what I am trying to say? It's about ensuring you're at least not guaranteed not optimal. You can leave it floating if you want but thats not the point... As for me being DR centric, well thats why I am doing these exercises- to stop me thinking like this. If it makes you feel better whatever, I don't care as long as counting my way it is under 10 moves. You can still leave out the last move if it matters so much.
