Saturday Afternoon Chess thread 12-18-2021

(h/t Howard Staunton for the pic. Unfortunately, I could find no other information about it)

Moviegique 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 (1489)

Goal: White can force mate in 3 moves
Hint: Set up a double check

Intermediate Problem - Black To Play (1485)

There's no short line to mate here, just show how Black can queen one of his pawns while preventing White from doing the same.

8/8/4pK2/Rr1k3p/1P6/8/8/8 b - - 0 1



Pic Note:

Apparently, this is an actual, hand-fabricated chess set:

The pieces are made of copper, half of them silverplated. I put felt under each of them, so they won't scratch the board. White on the silver and black on the copper ones.

The board is made of copper and stainless steel (the steels surface had the pattern on it, called pigskin) glued on a piece of MDF-board.

The board is 42x42 cm and highest pieces are around 7 cm.

More, including links to close-ups shots of the individual pieces, at the link.



Advanced Problem - White To Play (1455)

Execute the king hunt in the most efficient manner possible, making sure that Black's responses are the best possible.

Beginner Problem - White To Play


20211218 Problem 1.jpg
rn2kb1r/pp2pp1p/2p2p2/8/8/3Q1N2/qPPB1PPP/2KR3R w - - 0 1

1.Qd8+ Kxd8
2.Ba5+ Ke8 (or 2...Kc8)
3.Rd8#


Intermediate Problem - Black To Play


20211218 Problem 2.jpg
8/8/4pK2/Rr1k3p/1P6/8/8/8 b - - 0 1

The key to this problem is seeing that Black has an adanage with the rooks off the board. So simplification is the first order of business.

1...Rxa5
2.bxa5

White's pawn is closer to the queening square, but Black's king is close enough to intercept. But first:

2...h4

This threatens to put the pawn out of the reach of the opposing king.

3.a6 Kc6
4.a7

4.Kg5 h3 5.Kg4 h2 6.a7 Kb7 and White is stymied.

4...Kb7
5. a8=Q Kxa8

...and White's king is too far back to catch the h-pawn in time.

The ending might play out like this:

6.Ke7 h3
7.Kd6 h2
8.Ke5 h1=Q
9.Kf4 Qe1
10.Kg5 Qf1
11.Kg6 e5
12.Kg5 e4
13.Kg6 e3
14.Kg5 e2
15.Kg6 e1=Q
16.Kg5 Qg3+
17.Kh5 Qh1#


Advanced Problem - White To Play


20211218 Problem 3.jpg
r3k1r1/2pn3p/p7/1p4p1/1Q1P4/P2q2PP/1P4B1/2R3K1 w q - 0 1

1.Re1+

An obvious move. There are three possible Black responses:

(a) 1...Kf7 2.Qe7+ Kg6 3.Re6+ Kh5 4.Bf3+ Qxf3 5.Qxh7#
(b) 1...Kd8 2.Qe7+ Kc8 3.Qe8+ Rxe8 4.Rxe8#

Most of you probably found one or both of these lines; If you did, good job. But the longest line results from this response by Black!

1...Qe4!

This is not just putting up a useless block. The line that follows resembles the (b) line, which makes use of the bishop domininating the long h1-a8 diagonal. But look what happens

2.Rxe4+ Kd8

And now the White rook is blocking the diagonal

3.Qe7+ Kc8
4.Qe8+ Kb7

If 4...Rxe8 then 5.Rxe8#

5.Qxd7 Kb6

White was threatening 6.Re6+ and mate shortly

6.Re6+ Ka5
7.Qxc7+ Ka4
8.Qc2+ Ka5
9.b4#

Hope to see you 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.
