Carolina County Community Cat Conference is going on at a Resort exclusively reserved for Prime Members.
Some look-alike impostors have sneaked in. They all wear some fancy name tags which reveal their character.
Wear on Sherlock Holmes Hat and catch those cunning cats by examining their name tags closely. Initially assume all are prime cats unless you notice specific character in the name tag that reveals it is not prime.
Only basic knowledge of primality test is needed to catch the culprit.
Here’s a toughie for you-and no computers allowed!
I have created this unique chess puzzle which white mates black in many different ways, all in 5 moves, no matter what black does. Options do exist for both sides.
Basically, black is trying to prolong their life as much as possible. But no matter what move they make (not like there’s a ton if options after the first 2 moves), they shall always be mated in 5 moves.
And yes, the position is legal.
EDIT: It’s come to my attention that there is much more than 9 mates in one. In this light, just find as as you can.

I have finally come back to a bit of a warmer climate. I haven't really had a chance to properly work on my tan just yet, so today I went to the beach to get some sun. I might even book myself a treatment at the spa. After that it's again time to get my passport ready for the next flight...

I had a big, history-themed tour today. There are so many fascinating things to see that it can get pretty overwhelming.
I have to admit that lately I've been spending a lot of time on a relatively small area. I have to pick up the pace a little for the rest of the trip. The final destination is still far away.
The answer to this one consists of two common 6-letter words. Have fun!

Gardner argued that a "failure to specify the randomizing procedure" could lead readers to interpret the question in two distinct ways:
From all families with two children, at least one of whom is a boy, a family is chosen at random. This would yield the answer of 1/3.
From all families with two children, one child is selected at random, and the sex of that child is specified. This would yield an answer of 1/2.
Many formulations have a less technical problem: when a parent says that they have "two children and one of them is a boy", it's nearly impossible to read that in English without thinking "therefore the other one is a girl".
Can you rephrase the paradox so that the proper randomizing procedure is specified and the Bayesian logic is the crux of the problem?
At last! You've solved the mystery of the cards! Now that you've gotten into the hiker's computer in the hotel room, it's time to explore!
Good news! There is only one file. You double-click on it, but the smile falls off your face in an instant. More ciphers...
