the rules say that you can only make one move to defend. To be fair, Schuie conformed to that.
I would actually say it was two moves (in the same direction).
He started moving across slowly; looking in his mirrors and seeing rubens behind him - move 1
Then he looked in his mirrors, seen rubens moving to the right for the pass so MS moved alot quicker to the right - move 2
Thats my opinion. Rubens saw the first move, and wasn't expecting the second - quite rightly too.
