Hi SpAce,
I used the .png graphic format. The visuals look fine. I know of no specific forum rules otherwise.

It has been almost two years since I have added to this thread. I continue to like to create puzzles using HoDoKu. I create puzzles that have all of HoDoKu's default Hard steps plus I add XY chains. To avoid the drudge, I use the option to display the candidates. I now find that do not bother to 'white out' anymore. My X's do not seem to distract me these days. I remain very weak with finding AICs [that are not XY Chains} and ALS moves.

I do like the initiatives of StrmCkr and tarek to help one find the easier ALS moves like WXYZ and VWXYZ. Definitely for human solvers.

I do now search out the grouped 2 string kites and grouped skyscrapers. They are the perhaps the simplest grouped AICs. Also 3 string kites.

I like to use tarek's Sukaku Explainer and Sunnie's Sudoku Explainer as learning tools. Repetition seeing these moves in these solvers helps me to get them in my mindset.

I must highly recommend Phil's Folly for JE and for MSLS, in particular.

A new project called YZF_Sudoku holds considerable promise. The developer of YZF_Sudoku has implemented very thorough JE and MSLS. The JE will find aligned targets and will find exclusions from IBPs. With all possible steps, you can see all the various MSLS. The interface for YZF_Sudoku is inspired by HoDoKu although it is not Java based. It is my hope that the developer will add more of the HoDoKu UI features.

I have learnt so much from David P Bird's writings. Like the very best advanced technical writers, one benefits from returning to his writing again and again. No way you get it all right away. In a way, that is a good thing. For me, I am still returning and studying.
