Code:

 |...|..4|.63|
 |..1|..3|..2|
 |...|97.|8..|
 |---+---+---|
 |.34|...|...|
 |.9.|...|.2.|
 |...|...|61.|
 |---+---+---|
 |..8|.97|...|
 |6..|8..|1..|
 |91.|2..|...|
 *-----------*

Hmm - perhaps "grouped" moves are not in this solver/setter? Seemed relatively straightforward...

Interesting that I found a one stepper that involved essentially the same cells as Peter.

Quote:
AXY-wing -347 vertex (47)r8c2, pincers (34)r8c5 & (37)r9c3 with fin (5)r9c3; r9c3<>5,r9c5<>3
If xy-wing is true: r9c5<>3
If fin is true: (5)r9c3-r3*6c3=r6c1-r23c1=r2c2*-r2c78=r3c8-r79c8=(5)r9c79; r9c3<>5

Mine involved the same cells as well.

ER (5); r7c8<>5, sets up
M-Wing (34); r9c8<>4 + transport; r8c5<>4

As an aside, Happy Boxing Day, Peter. Very Happy
