### Hope this helps - from a newbie

Yessam,
1. Look at box 2 - Locked Candidates (5) in C6 Rows 1&2 means exclusion of 5's in box 8 C6 rows 7&9

2. Again Locked candidates (5) in Row 9 Cols 2&3 means excluding 5 from R3C7.

3. Naked triple in box 1 - 4,5 5,8 & 4,8 means excluding all 5's and 8's from R3C1 + R1C3.

4. Naked pair on Row 1 (2,6) means excluding 2+6 from R1C6

5. X-Wing on 8's R3C2 + R3C5, R9C2 + R9C5 means excluding 8's on R3C6, R9C1, R9C3, R9C6.

6. This leaves a naked 2 @ R1C9 and the rest is simple naked singles.

Hope this helps
