Did it, no green, no guess. When you get to the choke point, you'll find a chain of only two different numbers that reveals a contradiction in only a three or four moves. You can easily visualize that in your head.

Done. I'm afraid I of little memory needed to resort to greens as memory aids to reveal the contradiction when I reached the choke point near the end.

The trick in Saturday's Expert could be called "Parallel Block Pincer," or "Hashii" (ie chopsticks.) There were a lot of the same pairs, so that cell A had to be the same as cell B in another block. Those two cells operated in parallel against a third block. Choosing one of the possible numbers "guarded" six cells in the third block, prevented that number from being anywhere in that block. Thus the other number was the right choice.
