I'm just getting ready for the salsa...

Quote:
kite(2); r6c6<>2
w-wing(24) (2=4)r3c6-r3c2=r4c2-(4=2)r4c4; r2c4<>2, r4c6<>2
You could also do a lot of colouring on 2s if so inclined!

Two steps if my understanding of a DP is correct.

Quote:
6-cell DP23 r127c458. To prevent DP, r2c4=6 or r2c8=9
(6)r2c4-(6=8)r2c5-(8=9)r4c5
||
(9)r2c8-r2c9=r5c9; r4c7<>9

Kite 2 box1; r6c6<>2

I suspect my ER (2) did the same as Peter's Kite. My next (and last) move also was a W-Wing (24).
