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

And TheJamesMadison's movie thread will be up later this evening.

Easier Problem - White To Play (980)

Goal: White can force a mate in 3
Hint: eliminate the back-rank defender - at the appropriate time.

Chess On Display

On the way home from the PNW MoMe in Yakima last week, Mrs. Muse and I spent a few hours touring the Maryhill Museum of Art, which she has been wanting to do for a while. One of the main attractions of this museum is its collection of chess sets, which is on permanent display. Below are some photos we took with Mrs. Muse's phone. The lighting wasn't all that great and the shadows are annoying and hard to avoid, but we did the best we could:

More Challenging Problem - White To Play (966)

This is a very fun position to work through. I've heard that Garry Kasparov uses it in the chess Masterclass that he teaches (h/t David Llada).

Goal: White wins by either a quick mate or by forcing a KBN vs. K endgame
Hint: knights are very tricksy

Easier Problem - To Play

1.Qg6+ Qg7

Or 1...Kh8 2.Rxf8#

2.Rxf8+ Kxf8

This sacrfice eliminates the back rank defender. And now:


More Challenging Problem - White To Play

20190518 - Problem 2.jpg
8/8/3b2K1/2B5/7k/8/5N2/7N w - - 0 1

Before I worked through this problem, I thought that two knights can checkmate is if the king is in a corner, and even then, the position can't be forced. But with the bishops still on the board, the strategic situation is completely different.

Looking at the position, I saw that if I could get the White bishop to the d8-h4 diagonal, it would be mate. Of course, this is not possible, for Black could just move his bishop along the b7-h2 diagonal and block me wherever I went. And I can't just take the Black bishop because stalemate.

So I started looking at knight moves, which is how I found:


Because I saw that if 1...Bxc5 then 2.Nf5#. Also, if 1...Bxg3 then 2.Be7#. And 1...Bc7 results in 2.Nf5#. I was surprised to see these checkmates by two knights against a king that has not been driven into a corner square. I didn't think that was possible.

So the only move that Black really has is


And this allows White to close out the game with a knight fork:

2.Ne4+ Kf3
3.Nxd6 and with correct play, White will eventually win.

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.
