in only one step
AIC in r1c5
if r1c5=3 = r1c7,r3c56<>3
if r1c5=7 r5c5=9 r5c7=6 r3c7=3 = r1c7,r3c56<>3
or in more step for example
XYZ-Wing 1/6/9 in r2c6,r3c14 = r3c56<>9
and
Naked Triple 3,4,6 in r3c567 = r3c4<>6
and
XYZ-Wing 4/6/9 in r46c2,r6c8 = r6c1<>4
and
XY-Wing 4/6/8 in r4c9,r6c18 = r4c1,r6c7<>8
