Maybe it was too easy with just an Xwing on 3 in C2,9.

Simple coloring (3)

3r2c9=r8c9-r9c7=r9c1=> -3r2c1 (same elimination as the X-Wing)

Oh, now Marty's being just downright silly! Anyone on earth would see the 39-8 XY Wing (or the 89-3 XY Wing ) LONG before they'd look at some silly coloring solution! Come on Marty! Don't be silly! You must have too much free time on your hands to avoid finding the obvious - even after you've found it! (The next thing you'll know Keith has evolved to making pencil marks!!)

I don't think Keith will sink as low as pencil marks. I posted yesterday that I'm trying to avoid the X, XY and XYZ wings. I've been here for 12 years and much of that time has been spent learning techniques which I like to use from time to time.

No, but if I know a puzzle only requires a restricted set of techniques, I will look for those.

And yes, I still only use pencil marks for what I find to be x-hard puzzles. Pencil marks are a last resort for me.

I am not being grand. It's just that I find pencil marks to be a distraction from visualizing the patterns in a puzzle.

Oh! Now that makes perfect sense Marty! Now I understand. Hey Keith! It's nice to hear from you too!
