Good to see you restored.

Quote:
1. Nice double finned x-wing on 4s at r69c35 with both fins side by side at r78c5. Whichever is true the 4 at r9c6 is toast

2. Yet another finned x wing this time on 5s with the fin at r7c4 eliminating the 5 also at r9c6.

3. XY Wing <158> eliminating 5 at r3c9.

An alternate two stepper.

Quote:
ANP(15=8)r1c47 - (8=5)r3c6 - r3c9 = (5)r1c7; r1c23<>5,
RP45 r9c3 to r5c6; r9c6<>45
