Title: Chess Thread II
Post by: Unbeliever on August 25, 2017, 04:37:27 PM
There was a chess thread a few years ago that didn't go anywhere of interest, so I thought maybe we could try again.

I know some of you play chess. Do any of you players record your games? If so, I'm hoping you'll post some of your better ones here so that we can enjoy them.

I'll start by posting one of the games I played this past summer with a fellow named Dave, who can usually give me a bit of a challenge. Not in this game, though - I managed to trap his Queen after only 14 moves!

I was playing the white pieces:

1. d4........d5
2. c4........e6
3. Nc3......Nf6
4. Nf3......c5
5. Bf4......Be7
6. e3.......0-0
7. cd5......ed5
8. dc5......Bc5
9. Rc1......Bb4
10. a3......Ba5
11. b4......Bb6
12. Na4....Be6
13. Nb6....Qb6
14. Bc7.....resigns

I guess on move 13 he didn't want to double his pawns on the b file, as I thought he'd have to do. I was planning to move my Rook to the 7th rank afterwards, but when he recaptured with the Queen I saw that I could trap it. It's usually not easy to trap a Queen on such an open board, so I felt pretty good about it.

I wish I still had all the other games I've recorded over the years, but didn't manage to keep up with them. I have a few of the ones I played recently, though, so I'll see if any more of them are worth posting.

I hope some of you will post some of your's, as well.

I wish I had time to play some games here, but right now I don't. Hopefully I will eventually manage that, I'd like to see if I can find a good challenging game here. I know there are some players that I'd enjoy having a go at.

I don't focus much on losing and winning at chess - I look at it as two people cooperating to create something beautiful. Although winning is fun...

You'll probably kick my ass, but if you ever want to play a game and see me online, let me know.

I've tried learning Chess a few times, but I keep losing interest after about a week. By "learn" I mean memorizing the best opening moves, thinking a few moves ahead, etc.

It's not always easy for me to predict exactly when I'll be on-line, but if we could set up a specific time, we could give it a try. I have very few people to play with, that are any good, so I'd love to have a go with you if it can be worked out. I probably won't be back at the library until monday. I can post here, where i'm at now, but I can only be on-line for a few minutes at a time. At the library I can be on for about 4 hours, which would be more than enough time for a good game.

Learning chess isn't easy - I've bene at it for about 40 years or so, and I still haven't learned nearly as much as I'd like.

Try to find a good book on the game, if you can. The only way I was ever able to really start learning the game (I lost the first couple of hundred games I played) was to study the masters from the past.

A very good book on openings is "The Ideas Behind the Chess Openings"  ( I think by Ruben Fine) if you can find a copy of it. But the openings are only a very small part of the game - once you've learned the general principles, you can proceed without memorizing all those variations. I have a really lousy memory, so I realized early on that I wouldn't improve by rote memorization.

There are a lot of really good chess books these days, so if you want you can browse your local used book store and find many. Also, there are good videos on-line that may help.

Memorizing a few dozen famous openings ... not worth it.  Learning to see 2 or 3 moves ahead ... priceless.

I think you intended the 6th move by white to be Nxe4, didn't you, since the knight can't get from c3 to d4., and given that the knight later moves to d6.

There's a pawn on d6 capturing a pawn on d5.

Oh, you meant 13. Nb6 not B

I'm of the old positional notation.  The newer algebraic notation gives me fits.  I had to write the letters and numbers on a board to play postal and online.  But you got it wrong on 13.  And I see how the Q is trapped.  Nice game, bad notation.

I remember Bobby Fisher's P-K4 "Best By Test", LOL.  But get the moves right.  You drove me crazy for an hour til I figured out what the right move HAD to be.

And yeah I messed on 7.

Ach, you're right laddie! I fixed it. I'll be sure to be more careful next time.

I used the descriptive notation for a long time, but the algebraic is a bit easier for me to use now that I've gotten used to it.

Glad I solved it and you fixed it.  It was a pleasure to replay your game afterwards.  That Q trap was beautiful!

I even looked at it as black (nothing better than seeing both sides) and I didn't see it coming.

I'm mostly English as White and Sicilian as Black.  I'm not a positional player, LOL!
Title: Re: Chess Thread II
Post by: Unbeliever on August 27, 2017, 05:32:13 PM
I didn't see it coming either, since I thought he'd recapture with the a pawn, doubling pawns on the b file and giving me a strategic target with the weakened pawns. Then I was going to put my rook on the 7th rank, which is where rooks like to be - then they're called "pigs" because they can eat up a lot of the unmoved pawns or get behind any that have moved and gobble them up. Two rooks on the 7th are called a "hog", for similar reasons.

13.  Re1 is uncertain.  Both W rooks can move there.  This is a typical problem in algebraic notation.  Positional notation cannot make this error.  Please correct the notation so that I can follow your game (and I want to).

Chess is a game which I have always wanted to play well, but I just don't have the ability to see more than half a move ahead.  I find it fascinating, but I can't wedge it into my head what makes one move brilliant and another move merely a move.

It's hard and burns my brain to play sometimes.  When I was 20, I earned a trophy in an open tourney beating better players.  The next week in another tourney, I fell for a fool's mate.  I was all worn out.  But then there are sometimes the great moments when you sometimes see a series of moves the opponent can't parry and you feel like you actually understand the game.

And then the next game you are as dumb as a brick.

Chess is a humbling experience.

You're right again! Sorry about that. That's what I get for posting the moves without having a board in front of me and checking them as I go. I will from now on.

The 13th move is Rfe1.

Whew!  I was sure I was doing the moves wrong this time.  It is easy to get algebraic wrong and I have done that often.  To this day, I have to record my moves positionally.  I admit algebraic is more logically efficient, but I can't read it and picture the board.  With positional notation, I can.

I got it right on the 4th try, forcing myself to count the board on every move....  LOL!  Had to print out your moves and putting the paper right at the board!  Finally got it right that way. 

Saw the mate then coming at 16...  Nice game.

I have neat chess set - Medieval White and Brown pieces.  I have the chess set in the middle of the room so I can walk around it at look at the positions from all directions.  I used to have a larger weighted set on a homemade board but it "mysteriously disappeared" as some apartment roommates left.   I should build another board.

I haven't played a real person slow game in years and suck at computer chess (too fast).  I miss psyching my opponent.

I have one of those vinyl boards with the letters across the top/bottom and the numbers along the sides. I can use descriptive notation too, so next time I'll post both notations, if it's easier for you.

Mine looks like this:

Yeah, yeah, and the board was half the pieces, there were 4 players, the K was more powerful etc.  Do you think I don't know that stuff? 

And I wasn't offerring to play you.  Someone who knows the game.

That's OK, I was just wanting to learn the notation and follow other people's games.  But I keep having to spend all my time posting here ;-)

So if you will put one grain of rice on the first square, two on the next square and double each time until we get to the 64th square ...

Oh I know, you are European, so you will get mad, overturn King Offa's chess board, and lose your head

That is SUCH an old trick.  You don't even have to really know maths to catch that one.

When I write my games down I always use a check mark

(https://d30y9cdsu7xlg0.cloudfront.net/png/32500-200.png)

to indicate when a player is in check. I don't know why it isn't used by everyone, but I seem to be the only one who's ever thought of it.

If I had to make a guess, I'd think the + was chosen definitively over the ✓ probably after the advent of the typewriter because the + is (or at least became) standard on the keyboard and the ✓ wasn't and isn't.
Title: Re: Chess Thread II

That sounds reasonable. Why no check mark on the keyboard, though? I guess they had to pick and choose, since there was only so much room.

Post by: Unbeliever on September 06, 2017, 02:20:48 PM
OK, I checked all the moves (thrice!), and I'm pretty sure they're all correct. I played the white pieces against a fellow named Rick. I lost an exchange about halfway through, but was holding my own for a while, until I missed his 39th move with his Bishop to b6, which forced resignation, since I'd have lost at least a piece. Even though I lost this game it was still a pretty interesting game, especially the final position. This time I posted some comments, too. I hope y'all don't mind.


1. d4......Nf6
2. c4......g6
3. Nc3....Bg7
4. e4......d6

Rick has allowed me to build a strong center, which he intends to undermine if he can. This style of play is called hypermodern.

5. Nf3.....0-0
6. Bd3.....Bg4
7. h3.......Bf3
8. Qf3

I was a bit surprised that he was willing to exchange his good Bishop, since his bad Bishop is likely to be locked in for a while, but which turned out to be the piece he won with.

8.............Nbd7
9. Be3......e5

He's beginning to try to attack my center.

10. d5

In order to keep the long diagonal closed to his Bishop.

10...........c6
11. b4

To keep his d7 Knight from c5.

11............cd
12. cd.......Rc8

Posting his Rook on the open file, as he should.

13. Rc1

Can't let him control the file.

13............Nb6
14. 0-0

In order to connect the Rooks.

14............Nc4
15. Bc4.....Rc4
16. Ba7.....Rb4

I'd thought he might try moving his b-pawn to b6, to try to trap my Bishop, then move his Queen to a8 to win it. But I would've stymied that by Qe3 after the pawn move, so if he played Qa8 I could just take the pawn with my Bishop.

17. Rc2

To control b2, where I definitely don't want his Rook to move.

17............Nd7
18. Be3

Now trapping my Bishop was a real threat, so I just brought it back out of danger.

18............f5
19. Rfc1....f4
20. Bd2.....Nb6
21. Qd3.....Rd4
22. Qb5.....Nc4!

Here I should've played my Knight to b1 to protect the Bishop and the square a3, and would also have threatened his Knight (with my Rooks), but I wasn't looking closely enough, so I lost the coming exchange.

23. Be1.....Na3!
24. Qb7

Might as well get what I can.

24.............Nc2
25. Rc2......Rf7
26. Qb3.....Rc7
27. Ne2.....Rd1
28. Kf1......f3
29. gf........Qh4
30. Ng1.....Rc2
31. Qc2.....Rd4
32. Qc8+...Bf8
33. Qe6+...Kg7
34. Ke2.....Qe7
35. Qe7.....Be7
36. a3

So I could protect my Bishop which I wanted to put on b4.

36............Bd8
37. Bb4.....Bc7
38. Ke3??

This was a terrible move. I should have kept my King off the dark squares that his Bishop travels on. But I needed a square for my Knight, so I should've played Ke1. I also wanted to move my f-pawn to f4 to try to trade one of my doubled pawns. Plus, I wanted to get my King in the center, which is normally a good place for it in the endgame...but not this time.

38............Rd1
39. Ne2.....Bb6+
40. Resigns

I can only interpose the Knight (or Bishop) and must lose at least a piece, so resignation was clearly justified.


All in all I thought I played fairly well, but I have done better. I like playing against strong opponents, since it's more challenging. I often move too fast, before I've really seen as deeply into the position as I should.

I could post the game I won yesterday, but my opponent was not as strong as Rick, and the game was too easy, not all that interesting.

OK, I checked all the moves (thrice!), and I'm pretty sure they're all correct. I played the white pieces against a fellow named Rick. I lost an exchange about halfway through, but was holding my own for a while, until I missed his 39th move with his Bishop to b6, which forced resignation, since I'd have lost at least a piece. Even though I lost this game it was still a pretty interesting game, especially the final position. This time I posted some comments, too. I hope y'all don't mind.


1. d4......Nf6
2. c4......g6
3. Nc3....Bg7
4. e4......d6

Rick has allowed me to build a strong center, which he intends to undermine if he can. This style of play is called hypermodern.

5. Nf3.....0-0
6. Bd3.....Bg4
7. h3.......Bf3
8. Qf3

I was a bit surprised that he was willing to exchange his good Bishop, since his bad Bishop is likely to be locked in for a while, but which turned out to be the piece he won with.

8.............Nbd7
9. Be3......e5

He's beginning to try to attack my center.

10. d5

In order to keep the long diagonal closed to his Bishop.

10...........c6
11. b4

To keep his d7 Knight from c5.

11............cd
12. cd.......Rc8

Posting his Rook on the open file, as he should.

13. Rc1

Can't let him control the file.

13............Nb6
14. 0-0

In order to connect the Rooks.

14............Nc4
15. Bc4.....Rc4
16. Ba7.....Rb4

I'd thought he might try moving his b-pawn to b6, to try to trap my Bishop, then move his Queen to a8 to win it. But I would've stymied that by Qe3 after the pawn move, so if he played Qa8 I could just take the pawn with my Bishop.

17. Rc2

To control b2, where I definitely don't want his Rook to move.

17............Nd7
18. Be3

Now trapping my Bishop was a real threat, so I just brought it back out of danger.

18............f5
19. Rfc1....f4
20. Bd2.....Nb6
21. Qd3.....Rd4
22. Qb5.....Nc4!

Here I should've played my Knight to b1 to protect the Bishop and the square a3, and would also have threatened his Knight (with my Rooks), but I wasn't looking closely enough, so I lost the coming exchange.

23. Be1.....Na3!
24. Qb7

Might as well get what I can.

24.............Nc2
25. Rc2......Rf7
26. Qb3.....Rc7
27. Ne2.....Rd1
28. Kf1......f3
29. gf........Qh4
30. Ng1.....Rc2
31. Qc2.....Rd4
32. Qc8+...Bf8
33. Qe6+...Kg7
34. Ke2.....Qe7
35. Qe7.....Be7
36. a3

So I could protect my Bishop which I wanted to put on b4.

36............Bd8
37. Bb4.....Bc7
38. Ke3??

This was a terrible move. I should have kept my King off the dark squares that his Bishop travels on. But I needed a square for my Knight, so I should've played Ke1. I also wanted to move my f-pawn to f4 to try to trade one of my doubled pawns. Plus, I wanted to get my King in the center, which is normally a good place for it in the endgame...but not this time.

When I write my games down I always use a check mark

(https://d30y9cdsu7xlg0.cloudfront.net/png/32500-200.png)

to indicate when a player is in check. I don't know why it isn't used by everyone, but I seem to be the only one who's ever thought of it.

+ sign is standard, but I would sure know a check symbol...

I recommend https://lichess.org/

Easy to set up a new game and requires no registration. You can make an account, but that's only for keeping a score and saved games.

EDIT: btw, just click the "Play with a friend" link on the right panel, and click which side you want to play, you will be given a link you can share with your friend so they can jump right into play.

Thanks for the contribution, Mr. Obvious!

A nice solid kingside attack, there. Good job opening lines to expose the King.

Haven't been playing lately, myself. Too much other stuff going on. Life keeps intruding - just when I'd rather it didn't.

If they'd not distracted him so much, he'd probably have played an even better game. I hope all the hype doesn't cause him to get burned out before he's 10! If he doesn't get fed up with all that hype, maybe he'll someday be a world-class player.

I played some games yesterday, but didn't manage to record them. I won a game, but lost 5. I enjoy playing good opponents, it's more challenging. And Rick was indeed a challenging opponent. That whole winning/losing thing is just an ego trip, anyway. I play for the beauty of the game, and the fun of finding good ideas.

Vincent Keymer finished ahead of more than 50 Grandmasters in the GRENKE Open chess tournament. The teen has earned a spot in next year's Classic, where he would face the world's best players.

Vincent had 7 wind, 2 draws and no loss! And that against some of the best chess players in the world. I'd never heard of him until today, but I'm very impressed with what I've seen so far. Here's Antonio Recic with one of his games:

I lost a game to a 12 year old in the University chess club, and then the best player in the club lost to him.  It is AMAZING what young players can create in their minds.  I "learned" openings, he "understood" them.  There is a difference.

Chess never grows old does it?  I was watching a history show that very specifically talked about Ben Franklin playing chess with the French aristocracy, and while I loved the history, I kept pausing the DVD to try to figure out the openings and midgame moves on the board.  It was never detailed enough.    Probably Ruy Lopez and Giacco Piano. 

But of course it was just a show, so the board positions probably didn't reflect any reality.

Would have been nice though if they had shown the boards clearly with some accuracy of the times...

Yep, Mr. Franklin had a real passion for chess, but apparently not all that much talent:

There are times when a reply is idiotic and makes no sense.  And then there are times when a post is perfectly suited to the previous post.

You, sir, did a brilliant and rather unforgettable reply.

Thank You, thank you, thank you.  I enjoyed the links completely.

Well, all the rules of chess apply, with basically one change and one addition.  The addition is the superposition move where either you moved or didn't move, and the change is that the king actually needs to be captured, not merely checkmated.

Isn't the rule of "checkmate" a situation where the king WOULD be forcibly captured on the next turn, so there is no point in continuing?  Checkmate is just proof of King capture on the next turn.

Yes, but in QC, the king can be in a state of superposition, as can the attacking piece(s), so checkmate isn't enough; the pieces need to actually be in one state or the other.

There are rules about that; I don't know them all yet, but a piece must come out of superposition eventually.  Certainly when trying to capture a piece, you necessarily find out whether it's actually there or not.  There may be other circumstances.

I think I will drop out of this thread, LOL!  For now anyway.

And I had a weird dream a couple nights ago (I remember dreams).  I was playing a former office manager and a friend, and for some reason, they got to move my pieces around and take some off, and I won anyway.  As I recall, I had 3 rooks on back rank, they grabbed one, and I mated.  Dreams can be very strange.

Here's a game I played yesterday that was a lot of fun, in which I actually managed to sacrifice a Rook (I love sacrificing, even though Tartakover said "It's always better to sacrifice your opponent's men").

It's not a long game, only 28 moves.

I was playing the White pieces:

1. d4......d5
2. Bf4.....Bf5

I'm playing an opening called the London system (https://en.wikipedia.org/wiki/London_System), which is always fun, though it can be tricky.

3. Nf3.....e6
4. Nbd2...Bd6
5. Bg3.....h6
6. c4.......dxc4
7. e4.......Bg5
8. Bxc4...Bxg3

This is usually not a good idea, since it gives White's King Rook too much scope - especially if Black intends to castle on that side.

9. hxg3...Ne7
10. Qb3...b6
11. Rd1...c6
12. Nf1....b5
13. Be2....0-0
14. Ne3....Bxf3
15. Bxf3...Qa5+
16. Kf1

I wasn't worried about castling, since I wanted my Rook to maintain access to the half-open h file.

16..........Na6
17. a3.....Rad8
18. d5.....Rd6
19. e5.....Rdd8
20. d6.....Nd5
21. Nxd5..cxd5
22. Rc1....Rc8
23. Ke2...Nc5
24. Qe3...Qb6

Notice that nearly all of Black's pieces are on the Queen side (other than his f8 Rook), and since the center is blocked, he can't get any of his pieces to the Kingside to help defend his King, but White can play his pieces to either side, as needed, so it's time to take advantage of that.

25. Rxh6..gxh6
26. Qxh6..Nb3
27.Qg5+..Kh1
28. Rh1 mate

He was annoyed at me the whole game, because he wanted to play speed chess, with a 5 minute time limit for each side. But I hate doing that - I feel speed games are not chess, they're just "beat the clock."

If you ever want to play a game, I'm game.
Cave and I played a game in which we could pass on a move days later.
While that was long and did save my skin in one or two occasions as I needed a long time to find a good counter-move, it did seem fair seeing as we live in drastically different time zones.

Play him.  But he is good.  I might get back into this and try the winner.

Setting up the pieces where the cats wont get at them to "help" me set them up wrong would be good.  I found a plastic tub that fits over my table, so I probably wouldn't set them back up wrong again. 

Looking forward to watching your game.

Almost always.  I know it has an opening book it relies upon, and I think it has a randomizing factor to choose between moves that are of equal value.  By now you're out of the book, of course, and into the midgame.

That's actually pretty cool. I doubt it's the best opening counter, but I'm apparently usually shit at those.
I used to Always start or counter the start by moving one of my Knights into the field, regardless of what my opponent did.
I was once told by someone better than me, but not like an exceptional player, that I played a pretty good defence, but that my opening game was shite.
I've been trying out different plays since.
