| I can't believe I missed such an obvious XY Wing. (Ugh.) I ended up using the X Wing of 6's in columns 3 and 4 which opened up a couple of 568 XY Wings. I always seem to find the URs easily (this one has a 13 UR and a 35) but I never use them. |

There are two XY-wings 5-68 and -689. Look for both of them in C2. And therea BUG+1.
