Just today I read about this in the book "Who is Government" by Michael Lewis where he presents the case on how it can help find cure for rare diseases. You can read his article at https://www.washingtonpost.com/opinions/interactive/2025/mic....
Also highly recommend the book.

I have seen some other language wordles use yellow or green coloring of upper diagonal part when the consonants is right but wrong sound. That could be an approach. See how to at https://solladal.github.io/wordle-tamil/. (I don't think there is translation. But pictures should give the idea)

Totally agree with all your points. I also have a rating little over 2000 USCF. New players tend to over-emphasize on openings. To this day I know only names of about 5 openings. I do not know more than a few moves in them. I have generic replies for most of them.
Majority of the games of new players are decided by some stupid blunder. Blitz games do not help improve this area much. Like you said game reviews and puzzles are best.
navan | 5 years ago | on: Amazon Review Scam
I posted a 1 star review for a dell monitor with pictures because bands appeared in the middle of the screen after a month. Dell gave a refurbished unit as replacement. Amazon deleted my review after two months and blocked me from posting any further reviews for that monitor. I used to post regular reviews both positive and negative on Amazon. After this I just stopped posting any reviews to Amazon.

Interesting article and good question about whether we should program using graphs. In a different domain, languages like halide, tvm and tiramisu or in a way letting programmers create graphs for high performance.

I love lichess website too. I used to play on fics server. Once I switched platforms for my computer, I could not find a good client for fics. lichess is easy to use and get some quick chess time everyday. I like their tourney format also. Easy to get in and out unlike other places where you cannot get in after it started.

I have a similar USCF rating and I agree with everything you said. I would also add, when buying chess books, get books of the form "My best games" of top players and go over them. Try the side variations in those books as much as possible in your head. Do not buy opening books. Instead go over master games whose common openings match yours.

navan | 11 years ago | on: How To Think About Chess
I have an expert level rating. I agree with everything in the content. My games are very similar to what he describes. I have not memorized many openings. I just know a few moves in common openings and how to respond to a few quirky responses to them. I want to get to the middle game or out of my opponents memory as quickly as possible. I also sometimes deliberately make some opening weak moves to get out of opponent's memory.
One main thing I found in my experience is, majority of the games in amateur level are decided by blunders. I am not talking about small positional bad moves. These loose pieces are get mated in one move. If you are an amateur first focus on avoiding them by studying tactics before memorizing anything else.

navan | 12 years ago | on: How to Get Good at Chess, Fast
I agree with almost everything in that article. I have been playing chess for 20+ years. During that time I have spent several months at a time seriously spending all the free time to improve my chess. I have read numerous chess books, many of them multiple times. I have an expert level rating (USCF) now. I wish someone has told me to concentrate on tactics before going after openings or strategies. Nowadays for any new beginner once they learn the rules I tell them to practice tactics.
Learning positional strategies and all the fancy openings from the books was great. But was useless to improve my results when I was beginning. When I analyzed my games with the help of computer, I found 90% of the games were decided because me or the opponent missed a simple tactic which is just 1 or 2 moves deep. If this is the case in your games you should study tactics until you can find all 1-2 move tactics. It sounds easy. But I have seen a number of class A players miss these simple tactics numerous times.
Finally you will understand opening and positional strategies only if you can spot tactics in them. Once you do not find any tactical mistakes in your game you start to play positional chess. You will appreciate making good positional moves when you do not make silly mistakes.
