White to Play
Another thematic finish, but with a heck of a start.
View solutionFind the Fake Coin
There are 12 gold coins. One of the coins is fake. It is known that a fake coin weighs either slightly less or slightly more than a real coin. Using a balance scale, how can you find the fake coin, and determine if it weighs less or more than a real coin, in only three weighings?

Five young ladies (Liz, Marge, Sam, Ella and Jenny) went on five different hiking adventures. Each walked a distance of 3, 4, 5, 6, and 7 kilometers (random order). Each were able to take an extraordinary wildlife photograph in different locations (forest, meadow, mountain, river side and bushes) of different animals (rabbit, bird, deer, fox and bear cubs). From the clues below determine where and of what each girl took a photograph of, and the distance each travelled.
1. Liz walked twice as far as the girl who saw the deer. The girl who got a shot of the fox travelled one kilometer less than Jenny. The girl in the bushes was not the one who walked 5 kilometers. The girl on the riverside...

I can’t recall having so much fun looking at all the variations and the cooperation of the white pieces. It’s a great lesson on the power of the rook lift (going up to b4)as well.
View solutionTri Ad
Each of the clues below is for a word that begins with "tri". The clues do not refer to the words themselves, but rather to the word that must be added to "tri". eg. "A description of three goods to encourage sales" would be "triad".
1. Where you would find three peas
2. Passing through three intermediate places on the way to your destination
3. To fish with three hooks and bait
4. To hurl three things at once
5. A small container for three liquids

This win by I.A. Horowitz from 1931 has a mating pattern finish that everyone should know. The first move is quite spectacular on its own!

If you have been with this column a while, you will probably get the first move, but how about the follow-ups?

H.R. Agnel once composed a problem that was a mate in six:
1.Rg8+ Rxg8 2.Qd8+ Qxd8 3.Rxd8+ Ke7 4.Rxg8 Nd6 5.Bc5 b6 6.Bxd6#,but there was a shorter mate in five. Can you find it?

We’re going to finish off golden oldies with a task problem. White to play and mate without moving the king or taking a pawn.

This Golden Oldie is Edward Lasker’s most memorable finish.

This Golden Oldie is a doozy! White has all his forces arrayed, but what is the most efficient sequence?

Another Golden Oldie. Every player of the White pieces dreams of a sacrificial attack against the Sicilian Defense. Over 60 years ago Troinov got his chance. Here’s the game. 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 Nc6 6.Bc4 e6 7.0–0 Be7 8.Be3 0–0 9.Bb3 a6 10.f4 d5 11.e5 Nd7 12.Qh5 Re8?? At this point Black should have played 12...Qe8,...

Another Golden Oldie. One of the toughest things to do in chess is come up with a plan in a complicated position. Alekhine reached this position years ago and noticed something about a certain pattern based on the placement of the pieces. He noticed that the queen bishop was indirectly attacking the black King. He also noticed that if the a1-a8 ...

I have a hankering for posting some old favorites. So, we’ll do some golden oldies in the coming days, and they will be fun for people who have never seen them. This first one was inspired itself by an older Reti study—White to Play and Draw. That’s a hint for for the experienced players.

You might easily guess the first move, but can you see it all the way to the finish?

When finishing off a mating attack, you always look for the most efficient way. There are two ways to force a mate here, but one is much more efficient.

This time Black gets to give White a lesson on why White should not have been so greedy to go after the rook on a8.

We haven’t done a composed problem in a while. This one’s a mate in two and has an interesting story behind it. The great Jose Capablanca couldn’t solve it in 20 minutes. See if you can beat him.
