Hi Marty!
I had a similar solution and what I can see, the puzzle is already solved after your third move!

I must've missed something. I tried it again on Draw/Play and this is my grid after the first three moves and I'm stuck.

Code:

+----------+---------------+------------+
| 6  8   3 | 15  2    9    | 7   15  4  |
| 9  7   1 | 358 4    38   | 58  6   2  |
| 2  5   4 | 6   178  178  | 9   3   18 |
+----------+---------------+------------+
| 4  136 9 | 2   168  1368 | 356 158 7  |
| 5  136 8 | 7   9    4    | 36  2   16 |
| 7  136 2 | 138 168  5    | 4   18  9  |
+----------+---------------+------------+
| 3  4   7 | 58  568  2    | 1   9   68 |
| 18 9   6 | 4   3    18   | 2   7   5  |
| 18 2   5 | 9   1678 1678 | 68  4   3  |
+----------+---------------+------------+

From your grid I can only see singles, starting with r7c5=5.
And how you can know that r4c7<>8 ?

Right you are. That 5 in r7c5 escaped me, embarrassingly so.

R4c7<>8 because of c8's 8s are locked in box 6.
