Sorry, I forgot to save my post-basics grid. But there was a potential DP on 26 in b45. The killers were a pseudo cell in c2 which combined with other cells in c2 for a 389 triple; r2c2=6. The other killer was a 5 in r5c6; r1c6=6. The pincers of 6 set r1c1, r2c5<>6. After cleanup therefrom:
| Code: |
+---------------+-----------+---------+
| 4 1 79 | 5 2 6 | 3 8 79 |
| 789 6 2 | 89 1 3 | 5 4 79 |
| 389 5 389 | 489 48 7 | 2 1 6 |
+---------------+-----------+---------+
| 189 89 4 | 7 6 2 | 19 5 3 |
| 6 2 39 | 1 34 5 | 49 7 8 |
| 135 7 135 | 34 9 8 | 14 6 2 |
+---------------+-----------+---------+
| 2 38 157 | 38 57 4 | 6 9 15 |
| 1589 389 1589 | 6 38 19 | 7 2 4 |
| 1579 4 6 | 2 57 19 | 8 3 15 |
+---------------+-----------+---------+

| 789 6 2 | 89 1 3 | 5 4 79 |
| 389 5 389 | 489 48 7 | 2 1 6 |
|-------------------+-------------------+-------------------|
| 189 d89 4 | 7 6 2 | 19 5 3 |
| 6 2 c39 | 1 b34 5 | 49 7 8 |
| 135 7 135 | 34 9 8 | 14 6 2 |
|-------------------+-------------------+-------------------|
| 2 38 17 | 38 57 4 | 6 9 15 |
| 1589 e89-3 1589 | 6 a38 19 | 7 2 4 |
| 179 4 6 | 2 57 19 | 8 3 15 |

| How did you get to that grid? As I mentioned, I used a DP. Was it not needed? Did I not take basics far enough? Or did you play a move that you didn't mention? |

I just use lc/ls moves highest was a triple. I noticed one move you had not made in your grid was removig some 5's from block 7 (all the 5's in row 8 are in b7. I will work up a list if you need it. |

| Thanks, I did it again on Draw/Play and basics took me to the one-stepper XY-Wing. However, I did like my DP move, even though it shouldn't have been there. |
