8 Truths = {1c28 2c28 3r28 4r28}
8 Links = {1r6 2r4 3c6 4c4 r28c28}
rank0 pattern; 8 candidates to place, at most one per cell in r28c28, and the remaining positions can be covered in r46c46
=> -1r6c39, -2r4c379, -3r39c6, -4r37c4, -9r2c8
solves with a hidden pair, and locked pair
(effective eliminations for btte: -1r6c39 & -2r4c39)
great puzzle!!
