Saturday Afternoon Chess Thread 09-07-2019

WFM Marie Manelidou (GRC)

TheJamesMadison will be along later with the movie thread.

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 (292)

Goal: White can force mate in 3 moves
Hint: Draw the Black king over to the h file

r1b2r2/p3b1k1/2p1Bpp1/qp2Q1P1/3P2P1/4P3/PP3P2/2KR3R w - - 0 1

R.I.P. Pal Benko

Pal Benko, a chess grandmaster who was among the world’s best players for two decades, but who gave up his place in the 1969-72 world championship cycle to Bobby Fischer, paving the way for Mr. Fischer to become world champion, died on Monday in Budapest. He was 91.

The NY Times obit is actually worthwhile to read.

Intermediate Problem - White To Play (250)

Map out all of the mating paths.

Goal: Another forced mate in 3
Hint: I've found 3 mating lines

8/3Q4/pk6/1pp2Bp1/7p/1P2PP1P/P5P1/KN3bq1 w - - 0 1

Advanced Problem - White To Play (315)

Like the last problem. Map out the mating paths.

Hint: The longest forced mate is 5 moves

Dress Pr0n For The 'Ettes:

Today marks the return of my autumn/winter series Unsuitable Sideline Attire in which I spend every Sunday at the side of a rugby pitch wondering how my washing machine will cope.

Beginner Problem - White To Play

r1b2r2/p3b1k1/2p1Bpp1/qp2Q1P1/3P2P1/4P3/PP3P2/2KR3R w - - 0 1

The decision tree for this problem is pretty much a straight line:

1.Rh7+ Kxh7
2.Qh2+ Kg7
3.Qh6#

Intermediate Problem - White To Play

8/3Q4/pk6/1pp2Bp1/7p/1P2PP1P/P5P1/KN3bq1 w - - 0 1

1.Qd8+!

The key move. Black's king has 3 flight squares

#1: Kc6
#2: Ka7
#3: Kb7

1...Kc6 immediately loses to 2.Be4#

If 1...Kb7 then 2.Be4+ Ka7 3.Qc7#

Finally, on 1...Ka7, 2.Qc7+ Ka8 3.Be4#

Advanced Problem - White To Play

r3k2r/p2n3p/1pR3P1/3P3b/3P2pP/BP2P3/3KB3/R7 w kq - 0 1

1.Re6+ Kd8
2.Be7+

At this point, Black has 3 escape options. Here is the first one:

2...Kc7
3.Rc6+ Kb7 (or 3...Kb8 4.Bd6+ Kb7 5.Ba6#)
4.Ba6+ Kb8
5.Bd6#

And the second:

2... Kc8
3.Ba6+ Kc7 (or 3.Rc6+ Kb7 4.Ba6+ Kb8 5.Bd6#)
4.Rc6+ Kb8
5.Bd6#

And the third:

2...Ke8
3.Rf1 Nf8
4.Bb5+ Nd7
5.Bg5#

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.
