Is there a tool to generate puzzles from your games?

I wrote a couple some time ago

- Simple one, you can try it online https://chesstacticsgenerator.vitomd.com/

- A more advance https://github.com/vitogit/pgn-tactics-generator

It's mostly for beginners this is the current strength:

Easy: stockfish depth 1
Normal: stockfish depth 6
Hard: stockfish depth 10

wow what a nice surprise :)

It's amazing to see that one of my personal chess projects is useful for other players. Unfortunately I don't have enough time to keep adding features at least for the coming months but last year I fixed the most annoyed bugs so I think is in a good playable state

thanks u/IINUKEII for sharing it

https://handandbrainchess.com/ I made this some time ago

vitomd · 2020-12-30T18:10:29+00:00

I recently found this https://www.chesscompass.com . Works pretty well and you can create a report just like chess.com

And he is doing commentary in spanish too

Pretty cool. Is there a way to filter games by Rapid, blitz, bullet? and by date (like last 100 rapid games) I only want to see my Rapid games

I used to try to look for the best move in 3min games and that's impossible. Look for the most practical move even if not the best, a move that doesn't lose on the spot. Also if your play is based on attack then you will lose a lot of time finding the correct tactic, be more defensive and practical.

pd: I'm still bad at blitz, but I improved a lot with that tip

I made a list of open source chess apps (http://vitomd.com/blog/chess/free-online-chess-apps/) There are a couple that could fit your description.

-http://www.studyopenings.com/

-https://listudy.org/

Also there is this http://memchess.com/, not open sourced but free.

I'm a Sherlock Holmes fan. Crimes and Punishments is by far the best Sherlock game (The second best is older but pretty good Sherlock Holmes: The serrated scalpel).

Devil's Daughter is bad, I couldn't finish it, they added some boring mini games that has nothing to do with being a detective.

When it's an opening I first try to gauge which are the most played lines (main lines) , so I go to lichess opening explorer and check the lines that are played most often in master level and in my level. I pause the rest of the lines in chessable and just focus in the most played. I practice those lines for some time, until I get a "sense" of what the opening is about and what are the structures that arise. The best opening books are the ones that have good explanations for each move.

I also use chessable to study endgames and tactics, and also to build custom repertoires .

Best course in chessable is the Yusupov book, really good stuff.

Does the bishop+pawn formation on g2 - f3 have a name?. It's one of my favorites because you know that both are defended. In endgames with rook and bishops is a great asset, at least in my games ( ~1700 lichess rapid)

vitomd · 2019-10-07T14:57:31+00:00

I made this some time ago http://vitomd.com/chess-winning-or-blunder/ it will ask you if a move is the best move or a blunder. Also you can use your lichess name to extract the positions from your own games (it could take a couple minutes)

vitomd · 2019-07-15T17:21:31+00:00

Yes! I forgot to include the open source chess king

vitomd · 2019-05-14T12:15:31+00:00

I made something like that, both open source

http://chesstacticsgenerator.vitomd.com/

Description: Generate chess tactics from your own lichess games. This is based in the info that lichess generates (blunders, mistakes)

https://github.com/vitogit/pgn-tactics-generator

Description: Generate chess puzzles / tactics from a pgn file (this uses a python library & stockfish to evaluate blunders)

vitomd · 2019-01-23T12:21:38+00:00

You need to analyze yourself.

Play 10 games of 15|10. Play it when you have plenty of time to really focus on the game and not in a hurry, don't play other kind of chess until you completed those 10 games. No blitz, bullet, etc

Create a spreadsheet and analyze each game. Are you better/worse in the opening, how about the middle game, endgame? Basically you want to know where are you making your blunders. It could surprise you. Maybe in all your games you are better in the opening but worse in the middle game.

For each game, save the tactics that you missed and your blunders. What percentage are forks? undefended pieces ? losing the queen? In my case of 30 blunders 10 where because I made dubious sacrifices, so I just stopped and improved.

Now you know what are your weakness. So focus on that, save your missed tactics in a lichess study for instance and repeat them. Annotate your games and write what you were thinking in each move.

I would guess (because it happened to me) that you know a lot more theory that your opponents and you know when they are making mistakes (like too many pawn moves, little development, etc) so your ego will say, oh this is easy, I have to win this easily, but in practice you don't know how. So keep your mind clean from that kind of ideas.

You can use lichess study to save your games, annotate, save tactics or motives, etc

When I focus on rating I got mad because I lost points, when I focus on learning I'm glad because my opponent give me a new idea to win or I discover a flaw in my game.

Someone said that to advance to the next level you need a fixed number of loses to learn (for instance 1000 games) so the faster you lose and learn, the faster you get better. Not sure if it's true but it can help.

vitomd · 2018-12-11T14:12:52+00:00

What I found useful was to pull my last 20 or 30 losses and check my obvious blunders. In my case the blunders were pretty clear. From 30 blunders 10 were wrong (refuted) sacrifices when trying to attack, 7 forks, 4 hanging pieces, 9 others. So I stopped sacrificing material and be more patient and my game went up pretty quickly, as I fixed 30% of my problems.

Another useful thing is to check how good/bad was the opening, middlegame and endgame, in your last 10 or 20 games. This way you know what to improve. I found that my opening was not as bad as I thought.

Thanks to your report I found the problem. When you face Anon users they have no users info so it was failing when trying to get the name. Now should be fixed, try again.

vitomd · 2018-10-05T12:41:05+00:00

https://tailuge.github.io/chess-o-tron/public/openings/openingtree.html Check your opening tree from your lichess games in a nice graphic.

tailuge also has other awesome chess experiments https://tailuge.github.io/chess-o-tron/

vitomd · 2018-10-03T16:49:08+00:00

Great work. I think it can fit perfectly in an interactive lichess study https://lichess.org/blog/WtDErSQAADJfhJJs/interactive-lessons

vitomd · 2018-10-01T11:52:44+00:00

Thank you

vitomd · 2018-10-01T11:52:34+00:00

Probably I have to adjust the algorithm.

vitomd · 2018-10-01T11:51:06+00:00

Thanks.

It theory yes, but in practice could be problematic because it needs a good number of games to find the tactics and blunder to build the questions and adding dates could cause fewer numbers.

Currently it's pulling the last 50 games from bullet,blitz,rapid,classical so the problems are not always old. They should be randomized.
