Saturday Afternoon Chess Thread 02-22-2020

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 - Black To Play (Chess 4347)

Goal: White can force mate in 3 moves
Hint:

4k3/1p3pp1/p1r1p3/P3Pn1p/3N1q2/1P5P/6K1/1Q1RB3 b - - 0 1

Maia

Intermediate Problem - Black To Play (1104)

Goal: At the very least, Black can win a rook
Hint: A quick back-rank mate is not possible in this position

r5k1/3R3p/6pP/1p6/8/1PP4R/P4rP1/K7 b - - 0 1

A Fully Automatic Electronic Chessboard:

This is pretty ingenious. It even does the capturing/piece-removal automatically. More information here.

Advanced Problem - White To Play (1108 )

How does White win?

Goal/Hint: White can force a checkmate in 8 moves

Dress Pr0n For The 'Ettes:

Today's #ootd is a 1905-07 dress worn by the Russian Empress Maria Feodorovna (also the sister of Queen Alexandria). It is simple but so elegant and looks surprisingly cozy for this time of year. @state_hermitage #FashionHistory pic.twitter.com/JknFlz4yUF

Beginner Problem - Black To Play

4k3/1p3pp1/p1r1p3/P3Pn1p/3N1q2/1P5P/6K1/1Q1RB3 b - - 0 1

1...Ne3+
2.Kh1 Qf1+
3.Kh2 Qg2#

or if 2.Kg1 then Qf1+ 3.Kh2 Qg2#

Intermediate Problem - Black To Play

r5k1/3R3p/6pP/1p6/8/1PP4R/P4rP1/K7 b - - 0 1

1...Rfxa2+
2. Kb1 Ra1+
3. Kc2

Not 3.Kb2 because then 3...R8a2#

3...R8a2+
4.Kd3 Rd1+
5.Ke4 Rxd7 and wins

Advanced Problem - White To Play

r2qnrk1/pp4b1/2npb1p1/2pN1pP1/4P2Q/8/PPP1BP2/R1B1K1NR w KQ f6 0 1

The win is a forced mate, but it's a ways out:

1.Qh7+ Kf7
2.Qxg6+ Kxg6

not 2...Kg8 because 3.Qh7+ Kf7 4.Bh5#. Black has to take the queen.

3.Bh5+ Kh7
4.Bf7+ Bh6
5.g6+!

Do not be tempted by 5.Rxh6+ Kg7 6.Bxe6 fxe4 7.Be3 Nc7 8.O-O-O Nxe6 9.Rxe6 Rf5 and the win has evaporated.

5...Kg7
6.Bxh6+ Kh8
7.Bxf8+ Qh4
8.Rxh4#

Again, the mate is a ways out, but the decision tree doesn't have many branches on it.

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.
