I am all for swimming in the deep end, but a more 'waist deep' four step:

Quote:

kite(4) ; r5c8<>4
xy-wing(25-1) r5c8; r4c3<>1, r5c9<>1
w-wing(25) (2=5)r2c1 - r1c2=r5c2 - (5=2)r5c8 ; r5c5<>2
transport (2)r5c8 - r6c7=r6c3 ; r45c1<>2, r12c3<>2
transport (2)r5c8 - r5c4=r1c4 ; r1c3<>2, r2c5<>2 (mostly extraneous!)
ANP[(24)r1c48=(5)r1c8] - (5=1)r1c2 - (1=4)r2c3; r1c3<>4
