Calculating the diagonals of a given square and its colour

I made the following blogpost regarding the topic to help in visualisation exercises. I didn't know where to post, so I am showcasing it here. I hope that at least some of you all will find it helpful!

Feedback, criticism etc. is welcome.

I skimmed it and it looks pretty good but you forgot to explain the point of the exercise. Is this mostly to help blindfold players? 

/Also, you might want to fix the typo "Calcaluating". 

notmtwain,

Thanks for the warm comments!

It is mostly to help advance towards blindfold, but I heard that such exercises also help in visualisation. Paraphrasing Daniel Rensch - anything that helps you visualize better, will improve your calculation abilities too, while improving board awareness, and reducing blunders.

I will update the blog with the goal.

Thanks again!

/How do I fix typo in thread title?

If you go to the very bottom of "Home" page, there is a link to "Manage All Content" where you can edit your thread titles.

Fix'd! Thanks :)
