Crime Doesn't Pay

Here's an interesting piece by veteran chess commentator Bill Wall detailing all the incidents he could find of criminal activity involving chess in some way, starting with:

In 1622, Gioacchino Greco (1600-1634) was robbed of all his money (5,000 crowns) that he won in Paris from playing chess while on his way to London.

Some of the incidents are humorous, some are tragic, and some are just pathetic. Chess players are not always the most stable of individuals.

But this one just grinds my gears:

In 1989, the police raided a chess tournament in Los Angeles. The L.A.P.D. vice officers raided a nightly chess tournament held at Dad’s Donuts. They cited three men for gambling after finding $1.50 on the table. The police staged the raid after an undercover detective tried unsuccessfully to join a blitz chess game. The detective then pulled out his badge and said “all of you are under arrest,” as the L.A.P.D. swooped in.

I didn't realize that chess gambling had become such a yuuge problem in Los Angeles. I'd like to know who it was in the LAPD hierarchy who decided it would be worthwhile to expend departmental time and resources to setting up this sting operation. And for what? Are the citizens of Los Angeles safer because the LAPD bravely busted up a dangerous ring of chess ruffians?

Advanced Problem - White To Play (1126)

How does White secure a winning position? You don't have to play it out to the very end, but do show the crucial moves.

Hint: An amazing simplification will secure a winning position

Dress Pr0n For The 'Ettes:

Today's #ootd is a 1884 ensemble by Emile Pingat. He took inspiration from a man's traditional French court dress and feminized it. This type of outfit would have been worn at a ball or masquerade. @ShelburneMuseum #Fashionhistory pic.twitter.com/1EYv4G5ghK

Dreamy Lucien Lelong 1938 evening dress, @metmuseum.

Lightweight organdy is used to create this feminine gown. Each delicate stem of roses consists of an appliqué of ivory and green silk mousseline that has been outlined in a subtle flourish of coordinating bugle beads. pic.twitter.com/vEyijVXeI0

Problem Solutions

Beginner Problem - White To Play

6k1/6p1/3Np2p/2P1P3/1p2Q1Pb/1P5P/1qr5/5RK1 w - - 0 1

1.Rf8+ Kxf8
2.Qa8+ Ke7
3.Qe8#

Intermediate Problem - Black To Play

r3r1k1/pp3ppp/2p5/8/3N1P1P/7b/PPQR1q1P/3R1B1K b - - 0 1

Mate in 4:

1...Bg2+
2.Bxg2 Re1+

You don't want 2...Qe1+ 3.Bf1 Qxf1+ 4.Rxf1

3.Rxe1 Qxe1+
4.Bf1 Qxf1#

Advanced Problem - White To Play

3K4/kr5R/1p2b3/8/8/N7/8/5B2 w - - 0 1

1.Nb5+! Kb8

Not 1...Ka8 because 2.Bg2 Bc8 3.Nd6 and Black loses pretty much everything

2.Rxb7+! Kxb7

The start of the great simplification. Now White needs to snag the remaining bishop
3. Bg2+ Kb8 (or 3...Ka6 4. Nc7+ Ka5 5. Nxe6)

4.Nd4! Bg8

Why Bg8? The problem for Black is to find a square for his Bishop where White can't fork it (heh) with his knight. Trouble is, he can't! Let's look at some other options:

(4... Bg4 5. Nc6+ Kb7 6. Ne5+ Ka6 7. Nxg4)
(4... Ba2 5. Nc6+ Ka8 6. Nb4+)
(4... Bf7 5. Nc6+ Ka8 6. Ne5+)

Isn't that a kick in the head? No matter where he goes with the Bishop, the white knight will be able to catch him somewhere. Try it with some of the other options and see.

5.Nc6+ Kb7
6.Ne7+ Ka7
7.Nxg8 and wins.

Although it is a bit tricky. KBN v. K is a (difficult) win, made more so by the presence of a black pawn to complicate matters. But winning the pawn is not that tough:

7...Ka6
8.Kc7 Kb5
9.Nf6 Kc5
10.Nd7+ Kd4
11.Kxb6 winning.

Hope to see you all next week!

___________

Note: that cryptic line of letters and numbers you see underneath each board diagram is a representation of the position in what is known as "Forsyth-Edwards Notation", or F.E.N. It's actually readable by humans. Most computer applications nowadays can read FEN, so those of you who may want to study the position, you can copy the line of FEN and paste into your chess app and it should automatically recreate the position on its display board. Or, Windows users can just "triple click" on it and the entire line will be highlighted so you can copy and paste it into your chess app.

___________

So that about wraps it up for this week. Chess thread tips, suggestions, bribes, rumors, threats, and insults may be sent to my yahoo address: OregonMuse little-a-in-a-circle yahoo dott com.
