"Come To Chess City!"


Good afternoon morons and moronettes, and welcome to the Sunday 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 outside passed pawns and Modern Chess Openings. And, for those of you who aren't, you can use this thread to talk about checkers, or tiddlywinks, or Tigglypuff, or whatever you wish. Only please try to keep it civil. Nobody wants to get into a pie fight on a Saturday afternoon.

Endgame Study

This is another one whose solution eluded me. And after I saw it, I said "duh". Hopefully, you'll do better. It's White to play and win.

One Knight Too Many

Over on our awesome chess.com group, GOOCH asks:

I think one of my weaknesses is the middle game in general and, in particular, dealing with knight threats. I have trouble arresting their march into my territory, despite good pawn structure, and knights are almost always behind my most frequent blunders. Anyone have any good tips on this they'd like to share? I'm open ears...

Yeah, no doubt about it, knights are tricksy little guys. For example:


20160430 - 3 Knights Tango.jpg
FEN: [7n/k1K5/7n/1q6/2P5/8/8/7n w - - 0 1]

This position is one of the ones found in the Lomosomov Tablebases, a giant database that contains all 7-piece endings:

7-man tablebases were calculated in 2012 on Computer Science department of Moscow State University. Calculations were done on supercomputer named Lomonosov...The tablebases contain the exact evaluations (draw or moves to mate) for all positions with no more than 7 pieces on the board. The total number of positions in the tables – more than 500 trillions (500 000 billions).

There's an Android app that allows you to train on endgame positions. This is where this problem came from.

And I have not been able to solve this it. I can only get so far: after I queen the pawn, which is easy, I can usually figure out a way to force the Black king into a fork and pick off one of the knights. But then Black manages to bury the king in one of the corners with the knights right next to him, and once that happens, I don't see any way how to pry him out.

Actually, I don't even know if forcing a mate from this position is possible within the constraints of the 50-move rule. So perhaps this problem is of theoretical interest only.


Yoot Chess

In United States chess, things are definitely looking up:

Benjamin Kwon does not look like a gladiator, but you should see him play the Fried Liver Attack, a wildly aggressive chess opening that wages an all-out assault on the opposing player’s king. The opening is not for the fainthearted.

On a recent Friday afternoon, he beamed as he rattled off the first moves for both sides: pawn to E4, pawn to E5, bishop to C4, and so on, until he got to the real moment of attack, knight to G5. This is where the Fried Liver Attack gets hairy. “Nothing can block it,” he said, his face lighting up.

Benjamin Kwon is 6 years old.

According to the current ratings list, Kwon's is only 684, so he's not exactly a phenom. But he's conversing about chess topics intelligently so you know he's going to get better. And not just Kwon. These days, many schools all across the country have chess integrated into the curriculum.

Chess is even used as a tool to reform juvenile criminals based on the theory that it cultivates habits of thinking that will help them make better decisions with their lives.

And because of this, because we're finally accessing a huge talent pool, we're eventually going to be cranking out champions. Only from the bottom up. Right now, 3 out of the top 10 players in the world are from the United States (So, Nakamura, Caruana). And this is only the beginning.

Thanks to CBD for the tip.

White Mates in 5


20160430 - mate in 5.jpg
FEN: [1k1r4/pp5p/7p/1N1p1pq1/P2N3b/2P4P/1P2Qn2/R3RK2 w - - 0 1]

This problem is a good one to remember. The move sequence of the solution, and the piece configuration at the end, is one that comes up a lot in chess, and if you play enough chess, you'll eventually see this theme, or variations on this theme, occur in your games. Chess is mainly pattern recognition, and this is one pattern you should be able to recognize.

Thanks to 'Burn the Witch' for this problem


Snatching Defeat from the Jaws of Victory

There's not an actual chess club anywhere close to where I live (which is odd, this being a college town), but I did find a group of old guys who meet at a senior center every Wednesday morning for chess. And since I'm not all that younger than most of them, I fit right in. Here's a game I played at the senior center earlier this week. I managed, with great skill, to completely eff the whole thing up. This is the position after 11 moves:


20160430 - snatching defeat.jpg
After 11.Ng5
FEN: [r2q1r1k/ppp2p1p/2np3Q/2bNp1Np/2B1P1b1/3P4/PPP2PPP/R4RK1 b - - 0 11]

At this point, I figure I have a completely won game. Black will realize that the pressure on his pawn on h2 is irresistible, and even without that, there's a Big Gaping Hole where his king-side defenses used to be. So I sat there, patiently waiting for his resignation. Instead, he hit me with this:

11...Qxg5

OK, fine, Black wants to drag it out a bit. The pressure is now off his h2 pawn, but it cost him his queen. He's still lost.

12. Qxg5 Rg8

Remember that Big Gaping Hole I spoke about earlier? Well, it kind of works both ways, doesn't it? Now what am I going to do with my queen?

13. Qh6

Perhaps better was 13. Qf6+, but if 13...Rg7, I'm not sure what would be a good follow-up. He's threatening Rag8 and now I've got a rook battery staring down my throat.

13...Bh3
14. Qf6+?

And here my troubles begin. I should have played 14. g3 and let him have the exchange. I can afford it.

14...Rg7
15. Kh1??

Bzzzt! Wrong! 15. g3 was mandatory. What was I thinking? Now I'm busted.

15...Bxg2+
16. Kg1 Bxe4+
17. Qg5 Rxg5# 0-1

I see 3 takeaways from this:

1. Many times, the way to refute a sacrifice is to return the material at the appropriate time for a lasting positional advantage.

2. If you think you've got the game won, sit back, take a deep breath, and re-examine the position for counterattacking chances you might have to face. Don't be like the wide receiver whom the instant replay shows looking at the end zone as the ball slips through his fingers.

3. If you think you've lost, look again.

Despite my maladroit blundering, I still think I have a won game at the original position. But it wouldn't have been as quick as I thought, and I would've had to guard against counterattacks.

I was flustered at how quickly my I was able to turn a totally winning position into poo. So I totally missed 17.Qxg7+ Kxg7 18.dxe4, which puts me, basically, up a rook. White's 18th suggests that instead of 16...Bxe4+, Black should have played 16...Bf3+. OK, so I never had the slam dunk I thought I had. Dang chess.


___________

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.

___________

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.

4 Endgame Study
Isn't this just a rook and king finish? I don't see the black pawns helping. It's two turns to promote on f1 or g1. Only one to promote on h1, but the long diagonal would still be obstructed. Rb8+ forces  ...Ka1 or ...Ka2. Follow up with Kc2 (getting off the first rank, and any check from promoted pawns), threatening Ra8#, so the black king must march towards the rook.

I must be missing something that makes this not a standard rook mate exercise. (It has been a long time since I've played, and I was never particularly good.)

5 Guys, I'm signed up on chess dot com at the basic (free) level. Do you think it is worth getting one of the paid memberships that will offer their TV features, etc.? I'm still studying the real basics so the paid features may be more than I can use right now. Don't know if watching GM games on their TV coverage would be helpful or frustrating.

Posted by: JTB at April 30, 2016 12:21 PM (V+03K)

6 On the first puzzle, why not ignore the pawns?

1. Rb8+ leads to 1. ...Ka2 or ...Ka1
2. Kc2

At this point nothing Black does with the pawn situation will help (at least in my very rusty estimation). Neither 2. ...fxg2 or ...h1=Q will make a difference once White plays 3. Ra8#.

Yes? No? PIE???

Love the chess thread btw. Been a long time lurker.

Posted by: Donald Trump at April 30, 2016 12:36 PM (aRUb8)

24 OK, so on 1. Rb8+, then Black's response is 1...Ka2 (not 1...Ka1, because 2. Kc2 and mate next move).

So then the suggestion on the table is 2. Kc2

Black's response is 2...Ka3, and White has accomplished nothing. There's no mate next move. What next?

25 Since it is a Chess thread... Former CA Gov. Pete Wilson endorsed Ted Cruz. Wilsom was admittedly a squish, but he was very, very anti-Illegal Alien and won a double-digit victory over Jerry Brown's sister (then CA Treasurer) in '94 by supporting Prop. 187. He also appointed Janice Rogers Brown to the CA Supreme Court.

28 Not specific to chess but to classic games in general. I mentioned in the last book thread that I got a copy of 'The New Complete Hoyle, Revised. It covers just about any classic board or card game you can think of. I didn't even remember how to play checkers or solitaire, so it has been helpful as I glance through it. My copy was used from 1991. If you are in my never knew or can't remember, it might be worth a look.

I don't think so. Black would not move "P-R8(Q)" with a mate staring him in the face. He would move K-R3 and poof, no more mate-in-1.

Posted by: OregonMuse at April 30, 2016 12:46 PM (e8ge6)

35 So, looks like everyone got the first move of the endgame. 1. Rb8+ is correct. But what do you do next?

Posted by: OregonMuse at April 30, 2016 12:54 PM (e8ge6)

36 R-h8. There's no way for Black to promote pawns after that.

Wait, so instead of 1.Rb8+, you're proposing 1.Rh8, is that right?

Posted by: t-bird at April 30, 2016 01:04 PM (ANVXm)

43 I think Craig at 36 was proposing 2. Rh8, which would whittle Black's material down to one lone king and win eventually. Key word: eventually.

Man oh man am I rusty. Didn't even think about 2. ...Ka3. Back to the drawing board...

44 16 8 Your second problem with King and pawn vs King, queen and three knights. Is it white to play and win?

Posted by: Ironwood at April 30, 2016 05:23 PM (WLOZI)


Yes. Also, keep in mind that I do not know the answer. So if you get it, you probably should be running the chess thread instead of me.

Posted by: OregonMuse at April 30, 2016 01:07 PM (e8ge6)

45 I think Craig at 36 was proposing 2. Rh8 But if I capture the white pawn, how do you stop the promotion without dying?

46 Hey Al, White moves first because of privilege, didn't you learn anything in lefty school?

Posted by: Skip at April 30, 2016 01:11 PM (PFZvJ)

47 In your game I'd try 13.Qh4. The queen is safe from attack, covers h3, and retrains the possibility of Qf6+ in case Black plays Bf3. After that I'd think about challenging the Black bishop with Ne3 or Nf6.

Posted by: bof at April 30, 2016 01:12 PM (Bu4wL)

OK, so according to you, what we have so far is:

1. Rb8+ Ka2
2. Rh8

Now, work on that.

Posted by: Ben Had at April 30, 2016 01:19 PM (CriMx)

51 1. I got Rb8+ in the first problem, but still haven't figured out how to force a win. It looks like Black can march up and down the a-file until there's a draw by repetition. Moving the rook to h8 or b1 lets Black play fxg2. 2. I got the mate in five pretty quickly. 3. If 13. Qf6+ Rg7 14. Qxg7+ Kxg7, then you have 15. Nxc7 putting you up the exchange and a pawn with a much better pawn structure. In this situation I would start looking to trade material and head for the endgame.

He's the Al Sharpton to Iraq's Freddie's Fashion Mart - at least as far as being a loathsome idiot rabble-rouser. He's feared and loathed by many Shi'a in Baghdad and elsewhere - and not just the denatured, urbanized, sophistimicated ones. Though when fear of Sunni evil and violence is high, these same Shi'a see him and his JAM (militia) as at least on their side of the divide, and temporarily useful. His status as a tool of Tehran also earns him contempt and suspicion - unless fear of Sunni evil makes Tehran's anti-Sunni influence, too, temporarily useful. He also has a speech impediment that makes him mumble. Not good for a demagogue rabble-rouser.

110 With the three knights problem, I got this far: 1. cxb5 (any N move) 2. b6+ Ka6 If Ka8, White promotes the pawn and mates in three. So this turns into K+Q vs. K+3N, which is theoretically even in material. Just thinking about it makes my brain hurt.

Posted by: rickl at April 30, 2016 02:52 PM (sdi6R)

111 If fxg2, Rxh2 pins the g pawn.

Posted by: rickl at April 30, 2016 07:35 PM (sdi6R)


And now you see why 1. Rb+ was necessary; it was to force the Black king up to the 2nd rank to make that pin effective. This is what gives White the time he needs to snag both Black pawns.

117 A friend and I used to play the Fried Liver all the time. The problem with it is that if your opponent knows it, you are screwed. It's a cheapo opening and is 100% counterable all of the time. We used to know all the variations, even the ones not found in the books, and many times, countering the findings in those books. The Fried Liver loses every time. We found only one very obscure path where you might be able to come out somewhat even, but your pieces are not in the best places.

127 So this turns into K+Q vs. K+3N, which is theoretically even in material. Just thinking about it makes my brain hurt. So if White blunders and loses his queen, does K+3N vs. K lead to mate? I assume it would. When I was learning the game, I practiced the four mates with minimum material. K+Q vs. K and K+R vs. K are easy and straightforward. K+2B vs. K is trickier but doable. It usually involved some trial and error, though. But K+B+N vs. K gave me fits. I always dreaded having it come up in an actual game. I don't know if I could pull it off without violating the 50 move rule.

166 I'd like to ask all of you to pray (or offer positive whatevers) for our son.

He's decided to leave the hood where he's been living, and move June 1 to an apartment complex out of the city.  No roommate.  No drama.

He came by today and told me that all the gunfire Every.Fucking.Night. in his "neighborhood" had gotten to him.  Badly.

He said if it wasn't for his sweet dog waking him up by licking his face while he hears the gunfire and relives Helmand Province, he didn't know what he would do.

First he's shared with me about the shit he's been living through in Savannistan. 

There are literally several people/hood rats shot per night near where he lives.

Black Lives Matter my ass.

177 Son said he was sick and tired of walking his dog at night waiting for some hood rat to shoot at him with the ol' gun held sideways.  He said it was a matter of time before one of the bastards killed him.

I've prayed and prayed since he decided to move to the (expensive) apartment near the Hysterical District.  His vet roommate is away all the time, works nights, and doesn't get home until the wee hours in the morning.  Son is the one who has witnessed the shootings, and even gave first aid to a "victim" until the po-po and amberlamps arrived. 

So, his dad and I are relieved as hell he's moving. 

It's been almost like Afghanistan his living there for us.  Jeebus.

186 Well I figured the white rook should move to force the king to move on the first thread. And then I couldn't see how it ever got to a win for white, so I made a tasty lentil, ham and veggie soup to finish out the chilly wet day.

Hell, yeah.  It's actually out in suburbia, and he can walk to the big Kroger next to the complex.  There's countryside around and relative peace and quiet.  And he so very much needs that. No more gunfire every night.  It breaks my heart to know that he's been keeping his flashbacks to himself, but so great to know that his pup is there to comfort him and pull him through.

204 And in useless news here at Peon Manor, I spent more time today futzing with a little Honda 80 cc dirty bike motor salvaged from the dump (read: Free!). I had got the exhaust valve out of it last night, and went to polish it up today. Uh-oh! It was badly bent, and wobbled fiercely when I spun it in the lathe. Having nothing to lose, I kept tapping it with a hammer, until the runout was too small to see clearly. Then I coated it with valve grinding compound, chucked the end of the stem in my cordless drill, and pulled[/i[ on the drill while it spun, to lap the seat and valve together. That's a major no-no, but I didn't have a working rubber suction cup tool to do the proper oscillating lap technique. Nevertheless, I got contact between the valve and seat all the way around, and called it good. Did a quick lap on the intake valve, too, although it wasn't warped. Put the engine back together, clamped it into the big vise on the outside workbench, sprayed a shot of ether into the carb, and worked the kickstarter by hand. Zoom-zoom! It started right up, and idled for a good quarter-minute on the fuel I'd put into the carb bowl yesterday while vainly trying to start it. It didn't quit on its own, I had to shut it down by unplugging the magneto. So I am pleased as punch.

216 K+3N v. K + Q

That Android app you pointed to says mate in 46.  Not much margin to work with, though each capture starts the count-to-50 over again.

Thanks for making me look it up!  I didn't know FIDE removed the "exceptions to 50" stuff that computers found.

217 Chess puzzle:

1. R-b8+  K-a1 or a2
2. K-c2     any legal move
3. R-a8++

The Kingside pawns are a distraction.  Nice puzzle, since the first thing I looked at was how to stop the black pawns from Queening.  Couldn't see a way to do that.  I then noticed how constricted the Black King is, then it was easy to see.


Posted by: jbarntt at May 01, 2016 10:25 AM (qI7fD)

218 Oh, the puzzle I referred to in post 217 was the first one, endgame study.

Posted by: jbarntt at May 01, 2016 10:28 AM (qI7fD)

219 Re:217 Uh, no. That would look something like 1. R-b8+, K-a2 (a1 would be mate in two) 2. K-c2, K-a3 3. K-c3, K-a4 4. K-c4, K-a5 5. K-c5, K-a6 6. K-c6, K-a7 and now the black king is threatening the rook. It isn't mate and once you have to move the rook, black can queen a pawn. Correct soln involves getting the pawns out of the way I think. 1. R-b8+, K-a2 2. R-h8 At this point black can move the king or a pawn. Any king move just results in RxP. Same with queening the pawn (although RxQ.) That leaves the pawn on f3. It can either go to f2 or g2 taking the white pawn. If it takes the white pawn, then RxP and the last pawn is pinned to the king. If he pushes past to f2, K-e2 and now both pawns are under attack. They will both be gone in a couple moves and then it is a normal K+R vs K mate.
