That stockfish analysis feature on lichess is a game changer. I haven't played in a while, so this is all new and wonderful tech to me! My last online chess experience was the Internet Chess club in the aughts, and that client was basically IRC with chess bolted on. I wish, though, that it provided more justification when it points out an inaccuracy. The blunders (??) it points out are clear, but the (!?) inaccuracies can be a little hard to follow.

The poor bot-- that's harassment!

My kids have been getting pretty into chess lately and my knowledge of the game is from The Streets (I suck). I'd like to grab a couple of books that might teach me some proper methods that I can share with them, but my daughter will likely want to read some of it, too. So I'm thinking a book with a bit of a narrative to it rather than a bunch of puzzles or a chapter on a passed D pawn would be nice. Do you guys have any you could suggest?

I've got A First Book of Morphy in the cart already because it sounds pretty great.

I read some of Weapons of Chess in school and hated it. That's about my only exposure.

Seirawan's books fit the bill. I'd go for the tactics book as the best place to start, but good book on openings is just about worth the price just for the stories of his earliest days in chess as a kid. Opening 1. h4 to get his "cannons" out, queen raids, etc. I think most GMs might not admit that kind of thing, but that's where we all start.

Looking now and I think I'll grab his Chess Duels book. Seems like what I was looking for - thanks!

I was thinking more that the book might teach me some proper thought processes to pass onto them vs. my ad-hoc approach, but this site looks like a great one. I'm going to give it a shot and see if it's at their level. I would be nice to pin them against some other beginners vs. me being the punching bag after dinner.

This one broke a GM and blew my mind.



The solution he found was really interesting, but I can't reproduce it. I know that he won the queen by promoting the pawn to a knight, which put the king in check.

Loading it now in stockfish, the optimal solution it finds is different.

e: white to move

I'm not able to reproduce the outcome the GM got because I wasn't paying full attention until the end. I guess there's quite a bit of leeway with how the king moves. In a Stockfish study just now, it came up with this sequence that promotes the queen safely. In both this sequence and the one I witnessed, they block the initial Qh7+ with the bishop. Not sure why that's so much better yet.


Qh7+ Bf7
Qh4+ Ke6

I've done a few correspondence games now and I've had 2 or 3 where my opponent who isn't very highly rated has managed to open in a perfect way. I'm at move 12 and wondering if I should resign - it's so perfectly covering all avenues. And then the guy just blunders away the queen or loses a minor piece. Maybe I should learn a better way to open that isn't just king's pawn. knight, knight, and then hope for the best.

Oh no kidding? I am on lichess and didn't realize there was an opening book allowed/integrated in the actual live games. I figured they may have been using something.

Not sure how I feel about that, honestly. I guess it would be good to use it if others are, but I feel like it's a bad habit to get into.

Do official correspondence games have separate categories for human only play and ones that include engines? If it's seeking to show the epitome of chess, including engines, I don't see how it doesn't turn into an escalating war of people throwing money at stockfish instances.

Sub Rosa posted:


It's much more about having a lot of meta knowledge about chess engines. NNUE has changed things, but if we go just before we had Stockfish vs Leela as an example. Someone just doing analysis with one instead of both would be at a disadvantage. Easy to select a move if they agree, but when they disagree it's like asking a man with two watches what time it is.

So in practice you end up doing things like having engines check other engine's candidate lines, not just blindly playing Stockfish's top move at any arbitrary depth no matter how many cores you throw at it.

And all that is before recognizing that deciding which network to use with Leela is important, or that Stockfish is benchmarked for performance at lower time controls so gains in strength in lower time controls may not only not mean that it isn't stronger for infinite analysis, it could be weaker. So in practice there is a world of variant engines based on the more commonly known ones that may actually be stronger.

Thanks for sharing this with us. I'm completely fascinated that it works this way. I was skeptical, thinking that the competition would essentially be a secondary Top Chess Engine Competition, but I see now how that's its own thing. You're mastering the tools of a craft!


teppichporsche posted:

Honest question from a bad player: What is the point of choosing moves proposed by an engine/multiple engines? Aren't you just making worse moves that way? Curating moves doesn't make a lot of sense to me, since the engine is that much stronger than any human player.

My understanding from Sub Rosa's posts is it's a different level of competition, but involves human ingenuity and intuition as much as over the board chess, just different aspects. It's like you give two guys a block a wood and a knife and ask them to whittle out a figurine. And then in the other room, the woodworkers are allowed to bring all manner of lathes, CNC machines, full CAD design, etc, to make the same sort of figurine. In both cases, you're going to have one guy's figurine look better than the other guy's, but there's going to be a whole world of a difference in precision.

Freaking cool.

Puzzles on lichess and chess.com seem very different. I started off on lichess and have found the puzzles gradually increase with my rating to the point where I'm being served neat puzzles between some highly rated guys that are really interesting. They vary in type, but the quality seems consistent. On chess.com, admittedly I just started playing them and am at about 1100 so far, but the puzzles seem a lot more arbitrary. I get some with a pass rate of 1 or 2% that are really interesting, and then the next one will be some queen blunder where the soln is just to capture the hanging queen with a bishop.

It's been happening a bunch! Just got hit with some really simple mate in 1 after a couple of deeper ones and I blew it looking for the hidden fork or whatever.

I decided to focus on learning a single white and black opening to try and improve my overall game. About a week in playing a bit every day, it's been working. I shot up about 100 pts while still fumbling a lot of it. I think just having the structure and a short term goal has really helped me avoid blunders early on.

I didn't want to rely on memorizing lines, but my usual way of just winging it on a vague strategy of controlling the centre just wasn't working in Blitz and 10m.

I'm around the same boat you're in, but I'm struggling to properly visualize capture sequences after getting a reasonably solid opening in. It took me a long time to figure out this exercise: https://lichess.org/practice/basic-tactics/the-pin/9ogFv8Ac/BRmScz9t

I'm catching sequences like that pretty well, but like I said, I'll then lose a rook in the opening to a bishop or something worse. I did a whole bunch of puzzles on Lichess a while back and I feel like those developed my ability to spot more of the "long con" types of sequences, so maybe that could be what your game needs to round out. :shrug:

I'm working on the e6b6 and e4 opening lines from Gotham and I'm seeing progress. What gets me now is my opponent will accept my gambit or go on a line I know is supposed to be a massive loss for them, but then I draw a blank on the best response and end up with a Rube Goldberg position, lol. What I've decided I'm going to do when I have time is make a little paper notebook of the main lines of my two openings that I can just randomly look through to keep my memory fresh. The PGN files and the videos are good at explaining, but it's drilling it into my head that's a little tougher.

Just a quick effortpost on some books I've gone through since starting out earlier this year - thanks again for the recommendations here! Just some background: my kids got really interested in chess after finding my old mechanical clock in my office and I wanted to read some books to learn some things to transfer to them. My background before this was just informally playing against some friends in college way back in the day. I had bought a nice board and clock thinking I'd get seriously into it, but it didn't take.

1. Bobby Fischer Teaches Chess

What a great and unique book. It's just series of thematic puzzles with Bobby's guidance and explanations. It's designed by a pair of psychologists (?) or education experts who collaborated with Bobby to present the material in a systematic way that optimizes learning, and in my experience, it works. The book read front to back looking only at the right-hand pages, and then at the end, you flip it and go back-to-front. Big focuses were checkmate patterns to start, a lot of back rank work, and then it gets into more complex combinations. From what I can tell, the system helps commit patterns to memory by surprising you with unexpected switches just when you get into a groove - if that makes sense. My kids by far like this one the most. My 7 y/o daughter is about done with it and her play has really shot up to the point where she beats her mom and grandparents and makes me work. My 4 y/o boy is about 1/2 through it, but being 4, he only grabs it in spurts between lego building and harassing his sister.

2. A First Book of Morphy

This is the next best one. It presents one Morphy game per chapter, and each chapter is based on a basic principle of chess, which Morphy apparently developed and/or put into popular practice. The games are explosive and dynamic: perfect for re-enacting on a live board. Morphy plays guys like The Great and Right Honourable Royal Duke of Brunwick, Esq. or something and just shellacking the guy all over the board with ridiculous queen-sac mate combos and clearly illustrating how the basic principles yield opportunities vs. opponents not following them. It's fun.

3. Yasser Seirawan - Winning Chess Tactics

This one was way over my kids' heads and it lost me in the first section, but looking through it now, I'm probably going to dive into it next. I think it's a good book to follow something like the Fischer book, which demonstrates a lot of the concepts through immediate example with positive/negative feedback, while this book seems to explore them more deeply. Still in progress.

4. Yasser Seirawan - Chess Duels: My Games with the World Champions

Someone on here posted about it being a good book from a chess history perspective and it delivers. It's full of interesting personal stories and accounts from him playing the best of the best. The games are pretty interesting, but I didn't go through all of them. I'll likely go back and look at these some more. I really latched on to his stories about Tal and that led me to: Tal-Botvinnik 1960: Match for the World Chess Championship written by Tal. That's on the way right now and I can't wait to read it. I really latched on to Tal's personality and games from Chess Duels and Yasser's recommendation of Tal's writing and specifically that book has me anxiously awaiting it.

Just wanted to share in case it helps out any newcomers.

I bought Winning Chess Strategies at a Waldenbooks in 1992 and I think I read it more times than I played chess until they invented the internet. It's still my favorite Seirawan book so far.

I might grab that one next. Either that or an endgames book, because I think Handknit made a lot of sense when he said the Soviet system starts from there since the game inevitably progresses to that point. Now that a player has to buy me dinner most of the time before they can fork my queen :smuggo: , I see those more often. I got back into the Tactics book and I'm really enjoying it now. He has an engaging style and his tests are really well thought out.

Thanks for these recommendations. I have a kid who is 3.5. I really can't fathom him sitting there and playing. How did you get your 4-year-old to play?

His older sister is super into it so that translates to enthusiasm on his side - I think that's the biggest factor. That and he really likes the battle/war angle of it. The other day he jumped into the kitchen behind me with both his fists cocked up ready to fight and yelled "I'm a Fianchettoed bishop!! ARHHHH" I think he got that from a chesskid lesson, lol.

They make big leaps in the 4s, though, and I doubt he would've sat still enough in his 3s. But yeah, his typical opening is e4, Nc3, Nf3. If he's defending, he'll do something like e5, and then will sometimes bump out g6 and fianchetto there and I've mistakenly called that the King's Indian Defense before I knew better-- and it stuck-- but my wife makes them refer to it as The Awkward Pawn Move instead when they say that. :nono:

When I do my e6b6 opening, they bug me all the time that I should be doing centre pawns followed by knights and then bishops. I should probably just trashcan that idea because my win rate online with it is like 45%, so I think they're right.

The other day he pinned my queen when I spotted him queen odds and wasn't paying full attention. That raised an eyebrow a bit.

Jul 11, 2011

No, we probably did promotion or something, I just mean that he gets the idea that it can't move when he pins it on the king - just seems tricky. He had one tonight where he moved a bishop to hit queen and xray (?) to a rook, too bad about the pawn guarding the square, but cool to see anyway.

I was a little proud of this one but the analysis dulled that a bit! I found a combo at the end that would have won a lot of material, but when he responded in an expected way, it turned into a fancy mate in 3:

3. f4 Bg7
4. Nf3 Nf6
5. Bd3 Qd7

32. Rf8+ Kh7

I was originally thinking after Rxd6 ... (c or e) x d6 Bxc8, that he would have done Nb8 for the obvious save and I'd fork Ne6 ... Kh8 and work from there.

7... b5 looks really good to me, because

1) you are gaining space on the queenside
2) you are forcing white to waste time moving the same bishop over and over
3) after 8. Bb3 Nd4 you can force an exchange of that bishop for your knight, and doubling white's pawns at the same time. Now white has nothing to show for all those moves spent moving that bishop around, and black has the bishop pair.

on the other hand, 7... Nxe4 wins a pawn, but white gets some compensation because your pawn on e5 is pinned to the king after white plays Re1 to chase away the knight. Maybe later white can play d4 and take over the center while your king is trying to get castled?

I struggle with #1 a lot when playing. Whether I'm taking space with a push, or creating weakness. I find that really challenging in the heat of the moment.

Hand Knit posted:

I was asked about a position in the discord and I wanna bring it in here because it's instructive.

Black agreed to a draw in this position. It's a win, but you need to know a handful of ideas to win it.



The key is that once you get your R to a1 with your pawn to a2, white's king has to stay on h2 and g2. You exploit that to get your king into position, and trade rooks favourably.

1...Ra1 2.Re7 a4 3.Ra7 a3 4.Ra6 a2 This is our basic set up. Now white is locked in place.

5.Ra7 Ra7 is just any passive rook move on the a-file. If white tries to move the king towards the pawn you have 5.Kf2 Rh1 6.Rxa2 Rh2+ 7.Kf3 Rxa2. If white's rook leaves the a-file you have 5.Rb6 Rg1+ 6.Kxg1 a1=Q+. These are your two basic ideas. Your goal now is to use your manoeuvreing advantage to generate a supported passer on the other side of the board.

5...h5 You want to exchange pawns on g4. The reason for this is that white's king, stuck on h2-g2, can defend a pawn on h3 but not on g4.

6.Ra3 or 6.gxh5 Kh6 7.Ra8 Kxh5 8.Ra7 f5 9.Ra8 f4 10.Ra7 f3+ 11.Kf2 Rh1 and we've forced white into one of our two basic ideas from move 5.

6...hxg4 7.hxg4 Kf6 This begins our kings long circuitous walk to g4. We have to exploit another idea to get there.

8.Ra6+ Ke5 9.Ra4 Kd5 10.Ra8 Kc6 11.Ra7 Kb6 Bringing the key to the b-file lets us move the king up the board without white being able to cut us off with the rook. Attempts to check from behind instead just transpose to game line.

12.Ra8 Kb5 13.Ra7 Kb4 14.Ra8 Kb3 15.Rb8+ Kc3 Our king on the 3 opens up a new idea for us. Because black is winning the 2v1 pawn endgame, black can 'defend' the pawn on a2 by threatening a rook trade. This allows black's king to walk along the 3 to white's weak g-pawn.

16.Rc8+ returning behind the a-pawn now fails to the idea we just discussed: 16.Ra8 Rd1 17.Rxa2 Rd2+

16...Kd3 17.Rd8+ Note that on 17.Ra8 Rc1 18.Ra3+ Rc3 you're also defending against the lateral checks. If white returns to defending passively you walk your king back to supporting the pawn. 19.Ra7 Rc2+ 20.Kf3 Kc3 21.Ke4 Kb2 22.Rb7+ Kc1 23.Ra7 Kb1 24. Rb7+ Rb2

17...Ke3 18.Re8+ again 18.Ra8 Rd1 18...Kf4 19.Ra8 Kxg4 and now black will win after f5-f4-f3.

Thanks to you and Yama for taking a look at it. That idea of pushing the pawn into the rook on the back rank is hopefully seared into my head now, because that would have blown the whole thing up. I thought I was fenced-in behind the rook on the e-file and didn't see it at all.

It’s a good idea to hit the custom puzzles and slide the rating range to around blitz level to build up the quick pattern recogn. The high rated puzzles are fun, but they don’t drill in much that can be of use outside of long time, for me at least.

I still miss some low rated motifs, but I can tell I’ve improved and can immediately spot some others.

It's good you're checking out Tal. His games are wild and entertaining. I can't say I took in much from the ones I played through, but I enjoyed them. His style is to just go hard and sac pieces to crack things open, whereas I play more positional and if I'm sacrificing, my main concern is "how am I loving this up??" So his games are neat to me!

If you're interested, look up stories about him. He was a really interesting character. Very hard drinker all his life born with a lobster claw-like deformity of one of his hands. Super lovable and funny guy that everyone seems to have stories about.

I've noticed my recognition of tactical patterns has shot up in quick games lately and it's likely due to getting into the habit of playing puzzle rush a couple of times a day. Contemplating standard puzzles to crack into a new rating level is a lot of fun and has value, but over time you end up getting good at solving deep tactical combinations and there's little opportunity to drill those fundamental combos that come up over and over again in lower rated games.

Reading Chernev's Logical Chess this am and this Lasker quote seemed like a really nice thing to remember:

In the beginning of the game ignore the search for combinations, abstain from violent moves, aim for small advantages, accumulate them, and only after having attained these ends search for the combination -- and then with all the power of will and intellect, because then the combination must exist, however deeply hidden.
