I usually do at least one VH+ puzzle from other sites on days that this site doesn't have a VH. This was an 'evil' one (i.e. VH+) from 1sudoku and I also enjoy doing the 'Advanced' puzzles that appear on Helmut's site on Saturdays.

| Good one Clement! Beginning with your grid I used the following forcing chain: (6=8)r1c2-(8=157)r123c1-(5=3)r5c1-(3=8)r5c6-(8=1)r5c4-(1=6)r3c4 => r3c2<>6. |
