				Less, elegant, but:
 
 
145xyzwing@R8C7, -4R7C7; then:
 
458xywing@R7C2, -8R6C7

				Hi everyone, 
 
 
in one step: 
 
AIC in r7c2 
 
r7c2=4 and -4 in r8c1, r7c78
 
r7c2=5 r5c2=8 r5c7=1 r8c8=4 and -4 in r8c1, r7c78
 
 
or 
 
XYZ-Wing 1,4,5 in r38c7,r8c8 and -4 in r7c7
 
and 
 
XY-Wing 4,5,8 in r6c2,r7c27 and -8 in r6c7 
 
 
Ciao Gianni |

				Looking at this again, you don't need the 145 XYZ wing first
 
 
if the pivot in r7c2=5 then r8c7=5, r3c7=4, r7c7=8
 
if the pivot in r7c2=4 then r6c2=8
 
 
Pincers of 8 remove the 8 from r6c7 and solve the puzzle |

				| That’s right - similar to Gianni’s AIC in that the puzzle solved whatever value you put in the pivot |
