Calculation Errors

[@danheismanchess]

Thanks for watching. At the end of the video, the dog barking is puppy Capa; yes, named after the World Champion from 100 years ago, Jose Raoul Capablanca! Want more? Check out my award-winning video on Making Better Chess Moves kzbin.info/www/bejne/gJ-kXminhamkbdU

Capa has a very high-pitched bark. :) He's named after my favorite chess player. If you get a female dog, you should name her Blanca.

[@danheismanchess]

Capa is a female. Our male dog is Harry, named after the kids' book "Harry the Dirty Dog"

[@DonnyPlunkett]

@@danheismanchess I incorectly assumed male because the puppy is named after Capablanca. Capablanca was male so I wrongly deduced that the puppy was male also. Capo would be the masuline in Italian. Like in the Italian mafia.

Your calculation videos are the most instructive I've ever seen on the topic. Anything involving working memory (chess or otherwise) is a huge struggle for me as my prefrontal coretex is defective (like a bad Windows operating system). So-called 'executive function deficits.' But I'm actually able to visualize and do some decent calculation using your methods.

[@danheismanchess]

Thanks, much appreciated. I try to break things down and elaborate, greatly helped by my students explanations of what caused their errors. Whenever there is an error, I try not to just say "That's a mistake; you should have done X" but instead ask "What was your thinking that caused that error?" - and I see the same, or very similar, explanations that occur frequently and I have tried to categorize them (ABC error, quiescence error, Hope Chess, Hand-waving, not asking "What are ALL the things that move does?", etc)

​ @danheismanchess Too many titled chess players, KZbin or elsewhere, are either too vague, ambiguous, incomplete, or way too fast with their instruction. I'm literally playing chess with a disability. A neurological disorder with a trivial name that nobody takes seriously. Same as what GM Eric Hansen has. But he doesn't have problems with working memory. His symptoms present in other areas. Otherwise, I'd probably be a lot higher rated than in the low 1400s to 1500s. That's why I like your methodology and original terminology so much. I've watched a lot of your videos and to familiarize myself with your original terminology and thought process. I was so impressed that I bought your Improving Chess Player book.

This is a great training position Dan and very instructive video. For anyone that is interested below is the FEN to spar the position. 4r3/4p2k/3B2pp/2r5/6n1/2b5/PP4PP/4RR1K w - - 0 1

Gary, thanks! Hope others can benefit from your comment.

@@danheismanchess During the pause the video moment, I also analyzed and then evaluated Bxc5, Bxe1 sequence going into the pawn up connected passed pawn endgame as much better for white. But then it was great practical training playing this position out against stockfish level 6 on Lichess.

There's around 4 minutes of dead air at the end of the video. Also, technically in the second position RxN+ is not checkmate because the Bishop can also leap in the way.

[@danheismanchess]

4 min of dead air. That is very strange. I made the video as normal, stopped recording, and uploaded. I wonder how that happened. I could edit the video and reload; not sure that is worth it. Yes, technically it is one more interposition to mate :)

For a student in training, would you recommend all calculations be purely mental, or do you recommend the student write down variations on a piece of paper while he is working them out? Perhaps, the latter may be more beneficial for when he wants to review his notes?

[@danheismanchess]

Good question. It depends on which exercise, time available, difficulty of the analysis, etc. Normally you don't write things down because in a game you can't anyway, so you want to practice "keeping track" of what you have seen without the aid of notes. But then there's something like the Stoyko Exercise (see #3.1 at www.danheisman.com/chess-exercises.html) where you write down everything you can possibly see, with no time limit. But if you are doing repetitious basic tactics (one of the best set of puzzles to do), you are not going to be writing your analysis.

Very nice🎉 I had b2 and a2 pawns and protected h7 with my black rook and analyzed as in this game exchanging a pawn for check and he blocked with his white knight which I traded one of my rooks which was by the connected pawns. I EXCHANGED A FREE BLACK BISHOP AND HE HAD W ROOK ON MY 7TH RANK AND W ROOK ON H8. I QUEENED ON B1 AND HE TOOK MY QUEEN WHICH I RETOOK WITH BLACK PAWN AND QUEENED OB B1 AND WON!
