Somewhat "extreme" move, perhaps not entirely justified by the "difficult" label - but the pattern on 3s just asked for it and it was fun
Quote: | (7)r4c3=(7-3)r2c3=r1c3 - (3)r1c7=x-wing(3)r12/c39 - (3=6)r6c9 - r4c7=r4c2 ; r4c2<>7 | (Written as an AIC as the more natural Kraken was heavy on ALS) |

Same target as Peter's, but a different pattern of 3s to get there:
(6)r4c2 = (6-3)r4c7 = r6c9 - r2c9 = (3-7)r2c3 =(7)r2c2; r4c2<>7 |
