Hillary! Clinton's Chess Set? *hic*

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 doubled pawns and fianchettoed bishops. And, for those of you who aren't nerdly enough for chess, you can use this thread to talk about checkers, or politics, or whatever you wish, only please try to keep it civil. Nobody wants to get into a Gaulish fish fight on a Saturday afternoon.


Today's pic is of a chess set you can actually purchase (or at least you could before the business closed). The rules for this game are the usual except for the addition of one, which boils down to: capture a piece, do a shot. I've never played this variant of chess before, but I'd guess that the endgames must be, ah, "interesting."


White Wins Material

This is one for you noobs, an exercise in situational awareness. Look at this position:


20160528 - White wins material 1.jpg
FEN: [2rqk2r/pp2bppp/2n1p3/1B1pn3/8/P1N5/1P2QPPP/R1B1R1K1 w k - 0 14]

After looking at this for a bit, you should be able to say "oh look, White wins material, like, right now." How does he do this? Highlight the blank line just below this sentence if you need a hint:
The knight on c6 is pinned

Did you like that one? OK, good, here's one that's a bit more difficult:


20160528 - White wins material 2.jpg
FEN: [r2k4/1pp2rpp/pn1b1p2/3n4/8/P4NB1/1PP3PP/2KRR3 w - - 0 1]

Again, White can win some material. How? Highlight the blank line just below this sentence if you need a hint:
White needs to force a Black piece to move so he can put pressure on another.

A New Old Kind of Chess

It has come to my attention that some of our chess noobs here have conveyed their fear and trepidation of getting into a game with those of us who are more experienced. So, I have a suggestion that might help: on chess.com, you can play two different varieties of chess, not varieties of rules, but varieties of time control. The first is "live" chess where you sit down at an interactive board with your opponent on the other end at his, and moves are conveyed back and forth pretty much in real time. This closely approximates the "look and feel" of OTB (over the board) chess. If you're just starting out, I can see how this experience can be a bit intimidating.

But, there's an alternative to this. Chess.com also provides what they call "online" chess, where the time control is measured in days, not minutes or seconds. So you can make your move, get up, and come back a day later to respond. How is this an advantage? Because this closely resembles what is called "correspondence chess", i.e. chess by mail, a time-honored chess tradition. Now, in correspondence chess, the rules governing what you can and can't do during a game are a bit different than OTB chess. For example, in OTB tournament chess, if you get into a really sticky, intricate position, you can't go to another table, set up the game position on another board, and play out the various lines to see which one would be more advantageous. That's strictly forbidden. But, in chess.com's online chess, as in the more traditional correspondence chess, it's perfectly OK. You can also look stuff up in chess books, if you want. That's permitted, too (what you can't do is use some kind of chess engine or endgame tablebase to analyze your game for you. That's right out).

But when you're in one of your online games, if you look to the right of the interactive board, and to the right of the list of moves, there is an "Analyze" link with a chessboard icon. If you click on that link, another window will pop-up that displays another interactive board with your game at the current position. You can then use this board to go back and review your the moves you've made so far, or, what is possibly more useful, you can enter "hypothetical" moves made by both you and your opponent, so you can look at the possibilities of what might happen if you make this move or that move. Let me tell you I make *extensive* use of this feature in all of my online games to map out potential lines. Of course, then my opponent makes a move I overlooked, and all of my analysis is now worthless. But that's OK, I can always re-analyze based on the new move.

Perhaps some of you may be asking, "well, if I can use the analysis board, so can my vastly more experienced opponent, so I'm still screwed." Well, perhaps. My point is, playing games "online" rather than in real time might help you not to feel so pressured to come up with a good move with the clock ticking down. The pace will be a bit more relaxed, and even if you still lose, you'll enjoy the game a bit more.

I'm getting to the point where I'm starting to prefer this kind of chess over the usual OTB variety.


Black To Play And Win


20160528 - Black to play and win.jpg
FEN: [6k1/q5pp/2p2p2/3p1P1P/8/1P5R/P1P1rr2/3Q1R1K b - - 0 1]

The decision tree of this problem consists of two main branches. See if you can complete both.


Endgame Of The Week

This is an endgame problem that might be tough for you noobs. It's White to play and win, win, win:


20160528 - Endgame.jpg
FEN: [3K4/5Bk1/8/8/2R5/p7/1p6/8 w - - 0 1]


___________

[Update: Solutions]

1. White Wins Material - Easy

1.Qxe5! and White simply takes the Knight. 2...Nxe5 isn't possible because it is pinned by the Bishop. So it really wasn't protecting the Knight on e5.

2. White Wins Material - Not As Easy

This one is a bit trickier. You need to notice that the Bishop on d6 is in front of the King, and in fact, it would be pinned if White could get that Knight out of the way. Fortunately, he can:

1.c4! Ne7

If 1...Nxc4, then 2.Rxd5 wins the piece outright.

2. c5

And now not only is the Bishop pinned, but the pawn is also forking the Knight. White can pick up either one at his leisure.

3. Black To Play and Win

Black's killer move is 1...Qe3! There are two responses by White, 2.Rxe3 or 2.Rxf2:

Branch #1:
2.Rxe3 Rh2+
3.Kg1 Reg2# 0-1

Branch #2:
2.Rxf2 Qxh3+
3.Kg1 Qg3+
4.Kh1 Rxf2
5.Qg1 Qf3+ (5...Qh3+ 6.Qh2 Qxh2#)
6.Qg2 Qxg2#


4. Endgame Of The Week:

So, looking at the board, it is obvious that the big threat is Black's pawns that are (a) far advanced and (b) connected. That's usually a deadly combination, but in this case, White has resources. He would like to immediately scoot his Bishop down there to a2 to stop the threat, but his Rook is in the way. So, he needs to gain time in order to free up the diagonal for the anticipated Bishop move. He can do this by:

1.Rc7! b1Q

This sets up a discovered check if White moves his Bishop. Black can move his King out of that danger, of course, but that will give White enough time for Ba2. So Black really doesn't have anything better than to get himself a Queen immediately.

2.Ba2+

This is the crucial position. Black has a several choices where he can move his King. And the move he makes needs to buy time to get his Queen away from the White bishop on a2. Some of the possible flight squares for his King, namely f6, g6, and h6, can be ruled out immediately since 3.Bxb1 leaves him with nothing. He can't move to g8 since that square is covered by the bishop. That leaves f8 and h8. So, why are these any different than the 3 moves to the 6th rank we've already dismissed? Because there's some tricky maneuvering Black can spring that will allow him to force a draw if White isn't careful. So:

2...Kh8 and White is pretty much forced to snap up that dangerous Queen before it gets away.

3. Bxb1 a2!

And that's the point. White *cannot* take that pawn. If he does, then it's stalemate. If this is hard to see, go ahead and capture the pawn, and then look at the board. You will see that there is literally no square available for Black's king to move to.

(...and this is one of the reasons why I love chess so much: In even seemingly lost positions, there can still be fighting chances to be found that can turn the tables. "To the last, I grapple with thee; From Hell's heart, I stab at thee...")

So what is White to do? Black's pawn is threatening either a1Q or axb1Q and White's rook cannot guard against both. So, once again, he needs to buy some time:

4.Rh7+ Kg8

Forced.

5.Rh1 a1Q

6.Bh7+ and White's rook eats the newly-minted Queen next move, nom, nom, nom. And wins.

Now, back to move 2, Black's other option to get out of check is to move his King to f8. White can still achive his objective, but the smaneuvering will be just a bit different:

3.Rf7+ Kg8

Again, forced.

4.Rf2+ Qxa2

If Black moves his King then 5.Bxb1 with no danger of stalemate and that's all she wrote.

5.Rxa2 and wins.


So to recap, here is the complete solution without all my jabbering:

1.Rc7 b1Q
2.Ba2+ Kh8
3.Bxb1 a2
4.Rh7+ Kg8
5.Rh1 a1Q
6.gBh7+ 1-0

and the other branch:

1.Rc7 b1Q
2.Ba2+ Kf8
3.Rf7+ Kg8
4.Rf2+ Qxa2
5.Rxa2 1-0


___________

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.

6 I used to play correspondence chess by postcard, nowadays that'd be fine if you trust the person not to get a computer to help. That black to play and win, looks like QE3. The previous is C4 and C5. The last one not sure which way the pieces move, are black's pawns about to Queen?

Posted by: waelse1 at May 28, 2016 12:45 PM (AraCk)

7 With Black to Play and Win, I can see white avoiding checkmate, but ends up down in QvR.

12 And, for those of you who aren't nerdly enough for chess, you can use this thread to talk about checkers I remember when I was around 6-7 yrs of age playing checkers at our local park. This was mid- 60's. It was a park program. I learned to play from an elderly gentleman that was a volunteer. And NO, he was not a perv. We also played washers. Good Times.

17 Breaking news! I solved two of the chess.com daily puzzles this week (after a couple of false starts). Does anyone know if there is more than one solution to those puzzles? I think I see a legitimate move but the machine says wrong. It may be personal. The other news is I DID NOT lose to the computer on a chess.com game. It took 84 moves before the computer called it a draw. That I didn't make any fatal errors is proof that God is merciful or at least has a sense of humor.

18 That endgame--not just White to play and win, but has to "win, win, win"! That makes it harder. I found the (mere) win, but to triple that...

Posted by: Philip at May 28, 2016 01:14 PM (khA6h)

19 First one is simply Q takes E5./Second one is simply C4, Knight moves, and C5 winning the Bishop. 3rd one is QF3. If rook x F3, rook h2+, Kg1, Rook(E) to G2# , and if Rook takes F2, Queen takes H3+, KG1, QH3, KG1, QG3+, KH1, Rookx F2, Qg1, Qh3+, QH2, Qxh2#. Last one is RookC7, if B1Queen promotion, Ba2#, King moves, Bxb1, etc.

Are these variations by black?

Posted by: fluffy at May 28, 2016 05:43 PM (2hcmo)


Not sure how I answer that. So I'll say this: once Black makes his first move, there are two reasonable responses by White, hence, two main branches on the decision tree.

Hope this helps.

Posted by: OregonMuse at May 28, 2016 01:39 PM (UHKOQ)

27 In the 3rd problem,1... Qe3. If 2 RxQ, then 2...Rh2+ 3. Kg1 Reg2++. If 2 Qd3, then 2...RxR++. If 2 Rg3, then 2...Rh2++. If 2 Rf3, then 2...Rh2++ also. If 2 Rh4, then 2...Qf3+ and mate the next move. If 2 Rh2, then 2...RxR(h2)++. If 2 RxR, then 2...QxR(h3)+ 3. Kg1 Qg3+ 4 Kh1 (4. Rg2 gives qxR++) ...RxR 5 Qg1 and then either 5... Qf3+ 6 Qg2 QxQ++ or 5... Qh3+ 6 Qh2 QxQ++ If 2 QxR, then 2...QxR+ and mate the next move. I think that covers everything. Can't see any other possibilities.

Posted by: Evan3457 at May 28, 2016 01:45 PM (XSLU2)

28 The first one is easy, but the second one is puzzling. 1. c4 Nxc4 2. Rxd5 but Black is still two pawns up. I'm not sure how to proceed from there.

32 I'm not doing so well this week. I have no idea about that endgame. With "Black to play and win", the best I can come up with is Rxc2 followed by Qxa2.

Posted by: rickl at May 28, 2016 06:46 PM (sdi6R)


With 2. Rxd5, White has just gained an entire piece for his 'c' pawn that Black took last move.

So you figured out one of the branches of the solution. Good work.

Posted by: OregonMuse at May 28, 2016 01:55 PM (UHKOQ)

34 For the second one, white rook at E1 to E6?

Posted by: Evan3457 at May 28, 2016 02:00 PM (XSLU2)

36 If 1. Qe7... I can see a scenario where White ends up Queen versus Rook (if white sacrifices the queen)...I'm not sure that's good enough to 'win' though.

Posted by: GOOCH at May 28, 2016 02:01 PM (cxLzw)

37 Missed a step in the second scenario: 3. Qe4+ Kg1 4. Qg2# Of course, both scenarios are probably wrong for some stupid thing I'm overlooking. D.GOOCH

42 Oh, missed one possibility, but it doesn't help 2. Kg1 RxR dblch 3. KxR Qf2++ And any Q move other than Qd3 results in 2...QxR+ and mate the next move.

Posted by: Evan3457 at May 28, 2016 02:08 PM (XSLU2)

43 ...and Re1 is also followed by QxR+ and mate the next move, whereas on Rg1, QxR isn't + but ++.

45 I remember hearing a story about drinking chess: you had to drink the piece you captured. Drinks ran from shot glasses for pawns up to a magnum of campaign for the queen. First thing white did was sacrifice his queen, black passed out six moves later.

Yeah, I used to use Winboard, but I've found Tarrasch much easier to use for my purposes, which is mainly to set up positions and analyze them with the included chess engine, Stockfish.

If you find Winboard works for you, great, YMMV and all  that. It's a good app.

Posted by: Skip at May 28, 2016 02:26 PM (3wHFl)

55 Took me forever to find the key move for the endgame: 1. Rc7 This prevents the Black king from capturing the Bishop and sets up a nice trap. If 1 ...Pb8 = Q, then 2. Ba2 dis ch, and takes the queen off on the next move (and also prevents Pa7 as well). Then the rook captures the other pawn at leisure, and with the rook and king endgame (and the extra bishop can help or stay on the sideline), White wraps things up after a short chasedown. Whereas if 1... Pa7, then BxP dis ch with the same effect, only then the rook gets rid of the b-file pawn by c7-b7 and then takes on the next move. Too bad the Black king is so far from his pawns to matter.

57 Too bad the Black king is so far from his pawns to matter.

Right. And that's probably the main reason why White can avoid losing in this position.

58 Shot Glass Chess set: I have it.  I like to call it the "self-equalizing Chess set."  The better player will take more pieces and drink more early, and depending on how well he holds his liquor, that will give the lesser player a chance to catch up!

63 Oh, almost forgot, if Black moves his king instead of one of the two pawns on the 1st move, White can still play 2 Ba2 and run both pawns down in one of two ways: 1. Four rook moves (2 moves, 2 captures), or Let the rook "wall off" the black king and then move the King all the way down to run down the black pawns. Then the hunt for the Black King can begin.

67 55 Took me forever to find the key move for the endgame: 1. Rc7 This prevents the Black king from capturing the Bishop and sets up a nice trap. If 1 ...Pb8 = Q, then 2. Ba2 dis ch, and takes the queen off on the next move (and also prevents Pa7 as well). Posted by: Evan3457 at May 28, 2016 07:28 PM (XSLU2) That looks brilliant. That position had me completely stumped.

Posted by: Evan3457 at May 28, 2016 07:36 PM (XSLU2)


No. Meaning, Black can see that moving his King is an instant loser, so he knows he has to try something else.

I just watched a bit of Star Trek II: The Wrath of Khaaaan and this position is like the situation at the end: his ship is battered, damaged beyond repair, but with his last dying breath, Khan can activate the Genesis device, and turn it into a weapon that will destroy both himself and the Enterprise. Which is basically what Black is doing by trying to set up a possible stalemate.

79 I will contribute a chess story. Decades ago I toured with Ray Charles (low pay, but, Ray Charles). Ray played chess. Yes, a blind man can play chess. I was a newbie and Ray needed some fresh, so, one of Ray's guys comes to my hotel room door, knocks, and says "Mr. Charles would like to play chess. We understand that you play". What am I gonna say, "no"? I don't think so. So, I go to Mr. Charles' suite and we start playing. Ray is drinking Wild Turkey, neat. He is absolutely killing me, and I always thought I was no slouch. I am down to about 3 pawns, a knight, and my king and queen. Ray gets up to take a pee. I move one of his pawns, smiling at his minders, of course. Ray comes back, places his hands over the board, studies for a moment. Then says "So, where you workin' TOMORROW night?"

Posted by: Dirty Randy at May 28, 2016 07:51 PM (br2jI)


Well, "right now" was a hint that he could win material on his move, he didn't have to set up anything, it was just there for the taking.

And "wins material" means that a player can capture a piece without his opponent recapturing and thus evening things up.

That's a great story.

I played a blind guy once. He had a special board with raised squares so he could follow the diagonal, and of course, every piece felt different.

We drew. It was kind of a boring game, actually. Some games are like that.

83 Hey everybody. Sorry to threadjack, but is anyone else watching the Mets vs the Dodgers right now? It looks like the Mets pitcher's pitch struck a Dodger, the ump threw out the pitcher, and then the Mets manager went apeshit and got himself thrown out as well. The *one* thing I have the sports gene about is watching Dodger/Angels games in the summer... anyway if anyone can tell me if that's what happened or what else, thanks in advance.

No. I think you have things mixed up. The Black pawns move down the diagram, not up. So they're about to be queens unless White does something to stop them.

98 Don't know qdpsteve. Never get to watch baseball as I have no cable. But if you're a fan of the game and remember last years post season it was dejavu all over again. The Royals scored 7, yes 7, in the bottom of the 9th to beat the White Sox. Bad thing, now have probably lost Perez for at least a few games. Took a shoulder to the thigh from Cuthbert while catching a pop foul. Already lost Moose for the season and Gordon for 5 or 6 weeks on their collision. Would you guys please quit running into each other. Starting 4 or 5 guys every day who weren't on the opening day roster is not a good route back to the playoffs.

104 Late to the game, but haven't read the answers.

First game: Qe2xKne6
Black is down a Kn for2 pawns, but has a decent position.

Second game:
First thought - c2-c4
Second thought - Bg3-f2

If I had a lot of time on the clock OTB, or was playing CC, I'd look at the the bishop move.  I'm going with the pawn move.

Third game:  Skip

Fourth game:
Don't see how to prevent black queening a pawn, so must checkmate in spite of that.  Got to box in the black king, so:  Kd8-e8

re: Correspondence Chess.  It's been ruined by Computers.  Played it from the 1970s- 1990s, on and off.

122 Bridge on the River Kwai is on (or on soon, depending on time zone). For those interested I recommend "Ship of Ghosts" by Hornfischer. Story of the USS Houston and her survivors - she was sunk early in the war in what is now the Indonesia area. Many of her crew/POWs were on the Burma Railway line. Needless to say, appalling story. One odd tidbit in the book is the info that Thailand actually changed the name of a section of river so that the location of the large bridge that inspired the movie (bridge was multi-sectional and not made of wood) is now named "Kwai" - it wasn't at the time. Or something like that. Woman I knew a ways back had a Brit friend whose father was a Burma Railway survivor. He did some sort of memoir, I saw parts of the draft, don't know if it was ever published.

The house I grew up in was my grandmother's house before she died in 1960  (she bought it in 1939).  She worked for the Army Air Corp in WWII, and  bought books about the war  (because the proceeds went to buy war bonds).  Her son (my uncle) was in the Army in Europe in WWII.  So I grew up reading books she bought;  Guadalcanal Diary,  They Were Expendable,  American Guerrilla in the Phillipines.  She also had a copy of "Darkness at Noon"  that I wish I had read years ago.

140 54 30 Gooch I get what your doing as .......... Qe7 RxRf2, RxRf2 Qg4, Qe1# Qg1 Gaining no advantage , I'm not finding anything for black ------------ Once the rooks are exchanged, the black rook at f2 is no longer threatened by the white queen. The white queen has two legal moves where she can try to defend the king - G1 or G4. She can move anywhere else, but it just hastens white's defeat. If she goes to G1 it is mate when the black queen moves up to the 4th rank,. If she moves to G4 and abandons the first rank, the queen comes all the way down to earn mate. It's all moot, however, since white can claim the rook at e2. White finishes down material, but there is no immediate checkmate (as Evan demonstrates can be had by Qe3!) D.GOOCH
