Max chain length = 3:
hidden-pairs-in-a-column: c7{n1 n2}{r7 r9} ==> r9c7 ≠ 3, r7c7 ≠ 3
whip[1]: b9n3{r9c9 .} ==> r1c9 ≠ 3
hidden-pairs-in-a-column: c2{n4 n8}{r1 r9} ==> r9c2 ≠ 3, r9c2 ≠ 1, r1c2 ≠ 3
finned-x-wing-in-rows: n1{r4 r8}{c1 c4} ==> r9c4 ≠ 1
biv-chain[3]: r9c3{n7 n8} - r1c3{n8 n2} - c4n2{r1 r9} ==> r9c4 ≠ 7
