A BBDB for me with straight moves...
Quote:
kite(1) r2, c2 ; r5c4<>1
kite(4) r2, c6 ; r5c1<>
xy-wing(48-2) r4c1 ; r6c9<>2
grouped m-wing(68) ; (6=8)r1c5 - r6c5=(6-8)r6c9=r6c45 ; r4c5<>8
BUG+1 ; r5c9<>26=8
Here's a kraken one-stepper...
Quote:
kraken x-wing(2) ; r3c6<>2
x-wing(2) r5, r9

(2)r5c2 - (2=1)r1c2 - r2c1=r2c4 - (1=2)r3c5
||
(2)r5c9 - (6)r5c9=(6-4)r5c6=r3c6

One of my seven-steppers with an assortment of usual moves. One move isn't that usual for me, a Fin Transport, which I think may also be known as a Kraken X-Wing (having the fin in a different box than the X-Wing cells).
