Saturday Afternoon Chess/Open Thread (Featuring Dress Pr0n) 09-09-2017

Good afternoon morons and moronettes, and welcome to the Saturday Afternoon Chess/Open Thread, the only AoSHQ thread with content specifically for all of us chess nerds who pay homage in the temple of Caïssa, goddess of the chessboard. Also, dress pr0n. Each week, I pick out a few lovely, modest, conservative dresses for the 'ettes to admire and appraise. And, for those of you who aren't nerdly enough for chess, you can use this thread to talk about checkers, or other games, or politics, or whatever you wish, only please try to keep it civil. Nobody wants to get in the middle of a tomato fight on a Saturday afternoon, unless you're Eye-talian.

Looks like His Eminence is going down.

Problem 4 - White To Play (559)

The decision tree for this problem is quite complex. See how much of it you can fill out.

Hint: White mates in 6

Endgame of the week (PEC 36)

It's White to play. Black's king is in a very bad position. How can White take advantage?

Hint: Black can't stop you from winning the bishop

1.Rxg6+ fxg6

If 1...hxg6 then 2.Qh8#


Problem 2 - White To Play

2kr3r/ppp3pp/8/7b/2P2B2/6P1/Pq3P1P/R3QRK1 w - - 0 1


This fine moves generates two threats:

a) Qxc7#
b) Qxh5


To stave off the mating threat.

2.Qxh5 picks off the bishop.

Problem 3 - Black To Play (571)

20170909- Problem 3.jpg
6r1/5p1k/4qp1P/8/5Q1N/8/5K1P/8 b - - 0 1


Puts the question to White: What are you going to do with your queen?


Probably best. My chess app suggested another line, which I'll get to in a bit.

3.Nxf5 Rf4+

Black wins the knight and the game. To avoid this, my chess app did not move 2...Qf5+. Instead:

2.Qg3 Rxg3

And White's material deficit isn't so bad. He's still going to lose, but at least he has a knight.

(1... Qa2+ 2. Kf3 Qb3+ 3. Qe3 Qc4 4. Qe4+ Qxe4+ 5. Kxe4 Rg4+ 6. Kf5

Problem 4 - White To Play

20170909- Problem 4.jpg
r2qkbnr/2pb1pp1/p1np3p/1p6/2B1P3/2NP1N2/PPP3PP/R1BQ1RK1 w kq - 0 1

As I've already mentioned, the decision tree for this problem is quite complex, but I never could push it past 6 moves. That is, no matter how Black twists and turns (and in this problem he can do a lot of that), White can force a mate in 6 moves, max.

I'm going to give you the main sequence first, then I'll deal with the major sub-branches.

1.Bxf7+ Kxf7
2.Ne5+ Ke6
3.Qg4+ Kxe5
4.Qf4+ Ke6 (4...Kd4 5.Be3#)
5.Qf5+ Ke7

That's quite a chase.

But 1...Kxf7 isn't forced. What if Black decides not to take the bishop?

2.Nd5+ Kxf7
3.Ne5+ Ke6
4.Qg4+ Kxe5
5.Qf4+ Kd4

If 5...Ke6 then 6.Qf5#


Another big chase, different route, same result.

At move two, Black could either move his King to e6, d7, or e8. The main brank covers e6. Let's look at the others:

3.Ng6+ Ke6 or (3...Ke8 4.Rxf8#)


3.Qh5+ g6 or (3...Ke7 4.Qf7#)
4.Qxg6+ Ke7

There may be other branches in the tree I didn't catch. Let me know if you find any forced sequences longer than 6 moves.

Endgame of the week

20170909 - Endgame.jpg
1k6/5b2/1K6/8/8/8/1R6/8 w - - 0 1


Black really can't move the bishop. If he does, White is threatening 2 Rf8#.


1...Be8 is also possible, whereupon 2.Rf8 Kc8 3.Rxe8+ wins

2.Rf8+ Bc8


Now Black is in zugzwang. In fact, he only has one legal move:


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 past 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.
