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. |
