Sue de Coq (cannibalistic)
Use the candidates shared by two sets that fill a line-block intersection to make further eliminations around them.
All candidates have been entered in the empty cells.
cell A use 1 digits from 5. block D allows at most 0 of 5 in the 2 cells in C. the 5 cells in B use 5 digits from 1, 2, 3, 5, 7 and 8. column E allows at most 1 of 1, 2, 3, 5, 7 and 8 in the 2 cells in C. the 2 cells in C also allow at most 1 of 4. Filling all 2 cells in C requires every bound to be reached. Using 5 in C counts against both bounds and leaves too few digits. Cells A and C use all of 5 in block D; cells B and C use all of 1, 2, 3, 5, 7 and 8 in column E. Remove the crossed-out 5.
