IM Danny Rensch is a former child prodigy turned Chief Chess Officer of Chess.com, the largest chess website in the world. Danny rejoined me 8 years after his first visit to the podcast (Episode 18) to discuss all that is new with Chess.com. Inevitably, this means a detailed discussion of online cheat detection, and whether Chess.com thinks that their increased deterrence methods are working. But there is a lot more to discuss including: What goes into decisions of choosing commentators for an event? Lessons learned from some P.R. missteps related to the closing of Chess24, and changes to the Chessable product offerings.  Upcoming TV shows and documentaries related to chess. Why are so many of these shows related to cheating? Danny’s forthcoming memoir about growing up in a cult It is always fun to get a glimpse behind the curtain at the world’s biggest chess company, and you are sure to learn something about “chess business” in this conversation.

EP 427- Key Chess Improvement Principles with GM Noël Studer: The Fallacy of Accuracy Scores, Leaky Roofs & Information OverloadGM Noël Studer is a two time Swiss National Champion turned blogger, course creator and chess trainer. Noël is also a regular guest on the podcast, and as an avid reader of his blog, I always have plenty of questions for him. This particular interview tackles questions like the following: What has training for a marathon taught Noël about chess? Do Grandmasters like Noël make it sound easier than it is to “fix blunders?”  What are the traits of Noël’s most successful students?  We also discuss an update to one of Noël’s courses, his next projects, and why we both are a bit disillusioned with professional chess. There is always a lot to learn from GM Studer! Check out Noël’s updated course on studying chess the right way here (https://courses.nextlevelchess.blog/courses/simplified-chess-improvement-system?ref=bc4be0) Use the code perpetual20 to receive a 20% discount.

The Perpetual Chess Book Review series, Chess Books Recaptured is back, to discuss a new tactics primer that has been getting a lot of buzz, 100 Tactical Patterns You Must Know by FM Frank Erwich. My guest co-host is Kevin Scull, the host of the Chess Journeys podcast, and a dedicated student of the game. Kevin wanted to discuss this book because he felt it filled a glaring void in the marketplace and that it helped his game a lot. Nonetheless, Kevin also had a few quibbles with the book, so he joined me to discuss the pros and cons of this book, which overall is quite a worthwhile addition to the libraries of intermediate players and chess trainers alike. Because this book is so visual by nature, we kept this conversation short, and also made a companion video showing a few positions. The link to that, as well as timestamps and topics mentioned are below. Part 2 of this review, which looks at positions from the book, can be seen on The Perpetual Chess YouTube Channel: https://youtu.be/vaQuEx2CBgQCheck out the archive of book review podcasts here:https://www.perpetualchesspod.com/recapturedAnd the Spotify Playlist here: https://open.spotify.com/playlist/33uvcg7rb09ETWIgeAUCIR?si=0c11cd72fba548fa0:02- Why did we choose this book? Mentioned: GM Jacob Aagaard, Elizabeth Spiegel, Brooklyn Castle 0:06- Our quibbles with the book. 0:10- The structure of the bookMentioned: IM Kostya Kavutskiy’s review:https://www.youtube.com/watch?v=aC-Up1teylU0:17:00- Kevin’s Chessable coursehttps://www.chessable.com/chess-journeys-tactics-workbook-turning-knowledge-into-skill/course/268850/Thanks to Kevin for helping out!

Oleksandr Prokhorov is a Lviv, Ukraine-based chess organizer, trainer, FIDE arbiter and Twitch streamer. Ukraine has a rich chess history and has a vibrant grass roots scene in addition to famous natives such as Vasyl Ivanchuk, the Muzychuk sisters, and GM Ruslan Ponomariov. In recent years, I have marvelled at the persistent passion for chess in Ukraine  as I follow Facebook groups like the Love Chess Ukraine Facebook Group. Oleksandr and I discussed:  Is interest in Ukrainian chess as strong as ever despite the war? Is there still state funding for chess-related activities?  What challenges are presented by the fact that many of its top Ukrainian players are moving abroad in order to be able to compete internationally?  We also discussed a few notable Ukrainians who have been on the front lines, Oleksandr's favorite books and content creators, and what Oleksandr and his colleagues are doing to help the next generation of Ukrainian players. Hearing about the resilience of the Ukrainian people, and their continued passion for chess inspires admiration and respect.

IM Willy Hendriks is an award-winning chess author, historian and chess trainer. He has just released his fourth book, The Philosopher and the Housewife:Tarrasch, Nimzowitsch and the Evolution of Chess. This book is the completion of a trilogy which casts a new light on chess history and looks at the evolution of chess ideas. Willy’s newest book focuses on the early 20th century, with a particular emphasis on Aron Nimzowitsch and Siegbert Tarrasch. We tackle questions such as: Was Aron Nimzowitsch the most pretentious chess player of them all?  What does Willy think of My System?  Have the stylistic differences between Tarrasch and Nimzowitsch been exaggerated? What can we learn about engines and modern chess through reading about these players?  Our conversation is filled with fun stories and reflections about these players, along with the contributions of the third “main character,” Semion Alapin.   We also discuss Willy’s own competitive career and his potential next projects.

GM Wojciech Moranda is a high-level trainer, author and 2600+ rated player  who has worked with the Polish youth national team and IM Levy Rozman among many other students. I often recommend his books for ambitious advanced players, so I was excited to welcome him back to discuss his new Chessable Course, The Moranda Method: How to Calculate Like a Beast. In the course, and in our discussion, Wojciech lays out his core beliefs and fundamental framework for how to calculate in chess. His course is best-suited for 1800+ players, but Wojciech’s insights can help players at any level. In our conversation, we discuss common misconceptions about calculation, when one should stop calculating a variation, and then Wojciech lays out what he calls “the 5 elements of calculation.” Wojciech is extremely knowledgeable about chess, and its always a pleasure to speak with him. Check out our bonus video going through a calculation exercise on the Perpetual Chess YouTube page:https://youtu.be/0gSdFDkeeWQ0:00- What is the definition of calculation? 0:03- What are some common misconceptions about calculation?0:12- When should we stop calculating a sequence?What visualization advice can Wojciech give? Mentioned: Step 2 Thinking Ahead23:00- We discuss Wojciech’s “5 Elements of Calculation,” starting with what he calls “vision and perceptivity.” 49:00- Patreon mailbag question: Was Wojciech influenced by the work of legendary trainer Josef Dorfman?56:00- What is a typical day like for Wojciech?

FM Nate Solon is a data scientist, Chessable author, New in Chess Magazine columnist and the creator of the popular and insightful newsletter, Zwischenzug. Nate joined me shortly after we played in a tournament together to share his latest chess-improvement related thoughts and to reflect on recent lessons he has absorbed. We focused on a few themes in particular:  Why Nate thinks the challenge of learning new openings is often overstated, and the way in which he thinks chess openings “resemble poems.” How to avoid the trap of overemphasizing solving tactics in one’s training plan  Nate and I both discuss our experiences in the recent World Amateur Team tournament, and the ways in which the weekend tournament experience might be improved.  There is always a lot to learn from Nate, and I am confident your chess can benefit from this conversation.

Dina discusses the challenges she is currently encountering in her game as well as her current chess goals. Dina and I also talked extensively about her newest chess project, Chess with Dina. It is a chess academy that emphasizes the social side of chess improvement, and it has seen a fast growth since it launched last year. Dina discussed the building blocks that newer players should focus on, based on her experience as a product of Russia’s legendary chess education infrastructure. Lastly, we touched a bit on Freestyle chess, as Dina discussed why she thinks it might be challenging for the chess variant to catch on with newer chess players.

This week’s podcast is a discussion among friends. FM Donny Ariel is an NYC based former scholastic champion who has attained 3 IM Norms. These days he is  a working dad, who has recently decided to pursue not only the IM title, but the Grandmaster title as well. (Donny is chronicling this journey on his YouTube channel, The Road to Chess Grandmaster).   GM Jan Gustafsson,  as many of you know, is a renowned commentator, Chessable author, trainer, and frequent guest on Perpetual Chess. Jan and I are skeptical that Donny can attain the grandmaster title given his other obligations, but Donny is adamant that we overstate the difficulty of chess improvement. In discussing Donny’s quest, we tackle such questions as:  Is a coach necessary in the digital age?  How important are openings at Donny’s level? How much improvement can one attain through changing your psychological approach rather than training?  What is Donny’s “wall of haters”?  What trait do those who have earned the GM title have in common, according to Jan?  If not earning the GM title, what might Donny’s true goal be?  This was an entertaining conversation in which Jan actually gave more earnest chess improvement advice than he has in prior episodes.

Nikolaos Ntirlis is a Correspondence chess champion, and computer engineer who has become well known in the chess world for his vast opening expertise. Nikolaos is quite skilled at finding original opening ideas, and has grown popular through his books, and by highlighting new opening ideas on his Twitter/X account. The ideas Nikos suggests have often seen quick adoption by Grandmasters, and he has even seen moves he highlighted subsequently appear in the games of Hikaru Nakamura and Anish Girl. In fact, GM Giri wrote the Foreword to Nicolaos’ newest book, the excellent  Reimagining 1. E4. The book offers new ideas for White across many defenses to 1. E4, and explains opening concepts clearly without bombarding you with opening theory. In our conversation, we discussed the origins of Nikolaos’ opening enthusiasm, how best to use engines, as well as which defenses to 1.e4 were most challenging to combat theoretically. Nikolaos is also an accomplished chess trainer who hasworked with the national team of Denmark. In our conversation, he offered some helpful chess improvement advice with a philosophical bent.
