I don't see your w-wing? I do see an m-wing making the same removal. | Code: | *-----------------------------------------------------------*

m-wing
(7=1)r9c4-(1)r4c5=(1-7)r4c4=(7)r2c4 => r12c5<>7 |

A non w-wing solution is the two stepper: swordfish(9)r267c345 followed by xy-wing(17-9)r4c46+r7c4
or the two steps may be combined as an almost xy-wing: xy-wing(17-9)r4c46+r7c4=(9)*r4c4-r4c8=r5c7-r5c1=r8c1; r6c4*,r8c6<>9
