the above image shows a AUR on candidates {5,9} in r567c146
(2)r2c9 = (2)r2c4 - AUR59[(2)r5c4 = (67)r26c6] - (7)r1c6 = (7)r1c7; r2c9 <> 7 |

After the "B" puzzle I was in ALS mode, here's a neat HP move...
Quote: | hp(67)r26c4=(6)r4c4 - (6=2)r4c2 - (2)r4c5=r1c5 ; r2c4<>2
You could interpret it as an s-wing(26) where the (6)sl is created by the HP... |

Nice move Norm. I wish I could do better at spotting those things. |

A fun rambling solution.........
AUR(59)r13c58 external SIS r4c5=5,r6c8=5,r4c5=9; r3c8<>5
(5)r4c5-r4c7=(5)r1c7;
||
(5)r6c8;
||
(9)r1c6-(9=5)r3c5;
AUR(67)r26c46 external SIS r6c2=6,r2c9=7; r6c6<>6
AUR(67)[(6)r6c2=(7)r2c9]-(7=6)r2c5;
(2=9)r1c5-(9=2)r4c5-(2=6)r4c2-(6=2)r6c2-(2=5)r6c8-(5=7)r4c7-(7=5)r1c7-(5-2)r1c8..loop; r4c49<>2,r6c4<>2
xy-wing 2-59 vertex (29)r5c9; r6c1<>5
BUG+1; r6c4=5
