No movie thread today. As always, the chess/dress pr0n thread is an open thread, so there is no such thing as an off-topic comment.

Beginner Problem - White To Play (102)

Goal: White can force mate in 3 moves
Hint: First, Cut off Black's escape squares on the 'f' file

Intermediate Problem - Black To Play (1389)

Goal: Black can force mate in 4
Hint: You'll need both rooks to deliver the mate

Update: 'bof' busts this problem, says it's a mate in 15. He's right. Sorry about that. I really should do a better job verifying the solutions before I publish.

Advanced Problem - White To Play (131)

The forced mate is a ways out. Can you find it?

Problem Solutions

Beginner Problem - White To Play

20210717 Problem 1.jpg
8/6Q1/8/8/4q3/8/1K2p3/4k3 w - - 0 1

1.Qg1+ Kd2
2.Qc1+ Kd3

Intermediate Problem - Black To Play

20210717 Problem 2.jpg
8/2R5/4R3/5p1r/1pPk3r/1P3PK1/1P6/8 b - - 0 1

This was the solution I thought was correct:


2.Kf2 results in the same line.

3.Kf1 Rh1+
4.Ke2 R5h2#

But no, it doesn't work. 'bof' called a mate in 15, and he's right. Here's how it goes:

2.Kf2 Rh2+

(3.Kf1 Rh1+ 4. Ke2 R5h2#)

4.Rd7+ Kc3
5.Re2 Rb1+
6.Rd1 Rh1+
7.Kf2 Rbxd1
8.Re3+ Kd2
9.Re2+ Kd3
10.Re3+ fxe3+
11.Kg3 Rdg1+
12.Kf4 Rh5
13.c5 e2
14.c6 e1=Q
15.c7 Qe5#

I need to do a better job checking the solutions before publishing.

Advanced Problem - White To Play

20210717 Problem 3.jpg
3Q4/5q1k/4ppp1/2Kp1N1B/RR6/3P1r2/4nP1b/3b4 w - - 0 1

The tree is rather complicated:

1.Rb7 Qxb7

There are 5 other options, but they all lose quickly:

(1...Qe7+ 2.Rxe7#)
(1...gxf5 2.Rxf7+ Kh6 3.Qxf6+ Kxh5 4.Rh7#)
(1...gxh5 2.Rxf7+ Kg6 3.Qxf6#)
(1...Qg7 2.Rxg7#)
(1...Bc7 2.Qxc7 Qxc7+ (2... Rxf5 3. Qxf7+ Kh8 4. Rb8#) 3. Rxc7+ Kg8 4. Ra8#)

2.Bxg6+ Kxg6
3.Qg8+ Kxf5

(3...Kh5 4.Rh4#)
(3...Qg7 4.Qxg7+ Kxf5 5.Qg4+ Ke5 6.Re4+ dxe4 7.Qxe4#)

4.Qg4+ Ke5
5.Qh5+ Rf5

(5... f5 6. Qh8+ Qg7 7.Qxg7#)

6.f4+ Bxf4

(6...Nxf4 7.Re4+ dxe4 8.d4#)

7.Qxe2+ Bxe2
8.Re4+ dxe4

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.
