We will have a fishing thread later. As always, the chess/dress pr0n thread is an open thread, so there is no such thing as an off-topic comment.

Pic Note

Sorry, I have no idea.

Also, I couldn't make up my mind which should be the beginner problem and which should be the intermediate. So I apologize if you find that the beginner problem is too hard and/or the intermediate too easy.

Beginner Problem - Black To Play (1225)

There's actually more than one line that leads to mate within the problem parameters. If you find one, great, now go and see if you can find others.

Goal: Black can force mate in 3 moves in more than one line
Hint: Black has 3 options to escape the check, each one corresponds to a mating line.

Intermediate Problem - white To Play (1226)

Goal: White can force mate in 5 moves
Hint: Once you draw Black's king into the corner the rest is easy

Problem Solutions

Beginner Problem - Black To Play

20201107 - Problem 1.jpg
Q7/pppk1p1p/2n3p1/b3pb2/5n2/BKP5/P2PqP1P/RN3R2 b - - 0 1

Optimal is mate in 3:


or 2.Ka4 Qb5#
or 2.Kb2 Nd3#

...but these are suboptimal. The best move is to take the knight.

3.Bb4 Qxb4#

Intermediate Problem - white To Play

20201107 - Problem 2.jpg
6k1/6n1/1p3Rp1/4qp2/3pN1PQ/P2P3P/1Pr1r3/5RK1 w - - 0 1

This one is pretty straightforward:

1.Qh8+ Kxh8
2.Rf8+ Kh7
3.Ng5+ Kh6
4.Nf7+ Kh7
5.Rh8# 1-0

Advanced Problem - White To Play

20201107 - Problem 3.jpg
rn3rk1/pppq1ppp/3p4/4n3/2BQ4/8/PB3P1P/R5RK w - - 0 1

1.Rxg7+ Kh8

Running is better than recapturing: 1...Kxg7 2.Rg1+ Kh8 3.Qxe5+ dxe5 4.Bxe5+ f6 5.Bxf6+ Rxf6 6.Rg8#

2.Rxh7+ Kxh7
3.Qh4+ Kg6

or if 3...Kg7 then 4.Qg5+ Kh8 5.Qh6+ Kg8 6.Rg1+ Ng4 (6...Qg4 7.Rxg4+ Nxg4 (7...Ng6 8.Rxg6#) 8.Qg7#) 7. Qg7#)

4.Rg1+ Ng4
5.Rxg4+ Qxg4
6.Qxg4+ Kh6
7.Qg7+ Kh5
8.Be2+ Kh4
9.Qg3# 1-0

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.
