I unfortunately (!) spotted this early on... after so many in the B XY puzzle!
Quote:
flightless w-wing(15) transport ; (5=1)r7c5 - r7c1=r4c1 - (1=5)r5c3 - r2c3=r2c4 ; r3c5<>5
A solution path using four advanced steps (and ending with the same elimination!)
Quote:
xy-wing(58-6) r3c1 ; r6c5<>6
xy-wing(16-5) r4c5 ; r3c1<>5
skyscraper(5) c1, c8 ; r9c12<>5
kite(5) r7, c2 ; r3c5<>5
