Yet another XY Wing. Leren

Cheers! Do you have a particular method for spotting XY wings, or does it just take practise?

[Fortesque92]

I just completed a puzzle with an X wing, XY Wing and another X Wing. How exciting!

[Leren]

I use a computer to find the XY wings. To spot any pattern easily it takes the right DNA, which I don't have. Leren

haha I see.
