I would like to share with you some good fun that I recently sent to my whole family, for we have no less than five birthdays coming soon!
My two sisters, one niece, my son, and my nephew will be turning 54, 49, 17, 21 and 21 respectively.
I told them that I have thought of three different whole numbers. The PRODUCT of my three numbers equals the total of 54+17+21. However, the SUM of my three mystery numbers equals 49.
Your fun challenge is to figure out exactly what my three mystery numbers are.
I also have a wee dose of chess for you…
Black (to move) has an invisible knight somewhere on the d- or e-file.
Your chess challenge is to determine the optimal square for the invisible knight so that Black can then force checkmate as quickly as possible.
Solutions will be published on the day of my next blog post, and in the meantime I wish you a wonderful weekend now.
With all best wishes,
