After the Basics | Code: |
+-------------+-------+-------------+
| 145 7 145-6 | 8 9 2 | *134 36 15 |
| 48 3 9 | 1 5 6 | 48 2 7 |
| 158 56 2 | 3 7 4 | 18 69 1589 |
+-------------+-------+-------------+
| 6 4 8 | 9 3 7 | 12 5 12 |
| 9 2 7 | 4 1 5 | 6 8 3 |
| 35 1 35 | 6 2 8 | 9 7 4 |
+-------------+-------+-------------+
| 124 8 14 | 5 6 3 | 7 49 29 |
| 7 9 34 | 2 8 1 | 5 34 6 |
| 235 56 3-56 | 7 4 9 | *238 1 28 |
+-------------+-------+-------------+

Hidden UR 35 in row 69; r9c3<>5 opens a
W-Wing 36 with SL 3 in col 7 or row 8; r1c3<>6 which solves it. |

(6=3)r1c8-(3=4)r8c8-(4=356)r689c3 => -6r1c3; stte
if r1c8 is not 6 then r9c3 is 6 |

| Using the Type 3 UR on 35, r9c1=2 or r9c3=6. Trying each yields a common outcome of r3c2=6. |

Another solution is
anp[(56)r3c2|r1c3=ls(14)r17c3]-(4)r8c3=r8c8-(4=9=6)r73c8-(6=5)r3c2; -5r13c1

(6=3)r1c8-(3=4)r8c8-(4=356)r689c3 => -6r1c3; stte
if r1c8 is not 6 then r9c3 is 6 |

Very simple, elegant solution. Good Go
