M Wing Type A : (4=8) r6c1 - r45c3 = (8-4) r1c3 = (4) r1c2 => - 4 r56c2; lclste, or

M Wing Type B : (4=8) r6c1 - r2c1  = (8-4) r1c3 = (4) r1c2 => - 4 r56c2; lclste

For some reason Dan has posted this puzzle twice today. Steve responded to the other post.

Single candidate eliminations leading to an stte finish are 9r3c1, 6r3c2, 5r8c6 (calculated with brute force)
Nothing found eliminating any of these (even with complex nets), so
Code: Select all

 +-------------------------+--------------------------+--------------------------+

Almost 2-fish (4)c13\b47 + rfr1c3
[SS(4)r5c3*=r7c3-r78c1=r6c1]
(4-8)r1c3 = r45c3 - (8=4)r6c1
=> -4 r56c2; lclste

Hi Dan,

The single digit elimination stte list for this puzzle was small one : 9 r3c1, 6 r3c2 & 5 r8c6

This often indicates a relatively difficult single move stte finish puzzle, which was the case here.

The list for the puzzle for the 18th October was also a small one : 8 r1c6, 8 r1c8, 8 r9c7 & 5 r9c8 but Phil's Type AB M Ring caught 8 r1c6.
