TECHNIQUE EXCLUSION

You can use the suguru technique exclusion for solving puzzles in the next situation:

• A cell has 2 candidates (B3 has 2 candidates: 2 and 3).
• Two neighboring cells pertaining to another group each have those 2 candidates. (C2 and C4 both have 2 and 3).
• Both of those neighboring cells have the same extra candidate (C2 and C4 both have 4 as extra candidate).
• That extra candidate (namely 4) is also in another box of the same group as C2 and C4 (indeed 4 is also in C1).
• RESULT: that extra candidate is then deleted in the last box (you cannot enter candidate 4 in C1).

EXPLANATION: if you place candidate 4 in cell C1, then you must divide candidates 2 and 3 between cell C2 and cell C4 with the result that there are no candidates left for cell B3.
