Use the clues below to figure out which key goes in which box and to find the box where Beethoven's wig is being kept.
1. The green key goes to the third or fourth box
2. The wig is to the left of the fourth box
3. The wig is to the right of the first box

Kennel Confusion
7 dogs were boarding at the local Pet Lodge: Beau, Duke, Fluffy, Lady, Princess, Rover, and Spike. Each dog was in a separate run, all in a single row. One of the employees left the cages unlocked and the dogs have all gotten out of their runs. She needs to put each of them back in the right cage, but this is all she remembers. Can you help her get them into the right cages?
1. Spike doesn't like other dogs much, so he was on one of the ends.
2. Princess was somewhere to the left of Beau.
3. Rover was in the third run from the right.
4. The only dog between Fluffy and Lady was Princess.
5. Duke was directly to the left of Lady.

From H.R. Agnel’s 19th century classic, Chess for Winter Evenings. It’s a puzzle from one of his tales. It’s a mate in 5, but pretty direct.

This position arose in a 5-minute game I was playing online. My intuition told me a mate had to be there, but I will be honest with you—I did not see my last move until I arrived at that move.

I skipped side variations that led to heavy material loss. It’s an unusual mating attack. Here’s a weird clue: the knight is the piece that mates.

Chess teachers always recommend tripling on the file to attack, but not what White has done on the h-file; still…

When I realized I had forgotten one of Spassky’s most famous games, I had to include it. It was a dramatic occasion, and he annihilated a top grandmaster before move 20, and Boris had the black pieces no less!
