New book by noted art expert Celia Rabinovitch explores many themes
By SIMONE COHEN SCOTT
I first began to write this piece as a review of Celia Rabinovitch’s recently launched book “Duchamp’s Pipe, A Chess Romance”, but it turned out to be much more than a book review.
Celia, if you didn’t know, is a Winnipegger and, ever since we first met, I have thought her to be one of the city’s best kept secrets. She is an internationally known artist, cultural historian, author, educator, scholar, and speaker, and except for some slight exposure here in reent years – speaking at the Rady JCC and at the Remis Forum, she keeps a very low profile in her charming River Heights bungalow.
During the years 2002-2008 Celia was professor and director of the School of Art at the University of Manitoba. Her works have been exhibited at the Winnipeg Art Gallery and at the Plug In Gallery in Winnipeg. Elsewhere in Canada Celia has staged exhibitions at the Emily Carr Gallery of Art and Design and, in 2016, at the University of Victoria, where she was artist in residence. She has had broad exposure in Europe and the United States as well – exhibiting, teaching, and lecturing – in Florence, Vienna, New York, California, Cleveland, and Colorado. Her PhD, from McGill University, was on the history of religions and art history.
We first met in Israel, where she had been invited to give a seminar and lecture at the Israel Museum on components of the surrealism exhibit being held there.
Now – about the book: A number of years back Celia was asked to authenticate the provenance of a smoker’s pipe that had been given by renowned modern artist Marcel Duchamp to Grand Master of Blindfold Chess George Koltanowski who, in turn, had given it much later to Nikki Lastreto, his editor at the San Francisco Chronicle.
Celia’s research skills in the art world are well known, and tracking the path of the spiritual connection through the lives of two men, a game, and an artifact, from the late 19th century, when Duchamp learned to play chess, through to the early 21st century, when the pipe was sold at auction, was right up her alley.
She was able to establish that the pipe did indeed belong to Duchamp, and as such it was sold at auction by Christie’s New York for $87,500 US on the 21st of May 2016 – quite a windfall for Nikki Lastreto.
Celia’s detective work became the matrix for this book. She traces several elements throughout the saga – the two men of course, whose principle pastime was playing chess, but also the nature of the game as an entity in itself, the act of pipe-smoking as another, and time – the thread that weaves the story together.
In the author’s hands, time is not chronological. Celia weaves her story forward and backward as she develops her theme and explores each facet of the ethereal relationship between people and objects. Not to worry, though, because she thoughtfully provides a time-line in the back pages for readers who might like to sort things out.
The story becomes a beautifully written history book of sorts, as the atmosphere of the surrealism period of modern art begins to permeate the senses. It was a time, pre WWI, when certain groups of artists wished to jar the sensibilities of people living in what has since been referred to as “the age of innocence”.
The work that brought Duchamp to worldwide attention was his then shocking painting, ‘Nude Descending a Staircase’, which he entered in the Armory Show in New York in 1913. Later, he became even bolder, positioning a urinal in a photograph and calling it a fountain. (Dada art takes getting used to. Personally, I’m saddened that the artist’s inclination to shock the bourgeoisie has drawn attention away from the skilled painter and original colourist that he was.)
George Koltanowski, International Master of Chess, and Honorary Grand Master, was giving chess exhibitions in Guatemala and Havana, Cuba when the Nazis invaded Belgium. His family in Antwerp, including his mother and his brother, Harry, perished in the Holocaust. The U.S. Consul in Cuba offered him a U.S. visa. George could play chess while blindfolded – and win. He had, he said, a “phonographic memory”, and remembered, once told, what was in each and every square on the chessboard. He made his living at chess, both by playing in exhibits and tournaments all over the world, also by promoting tournaments and chess clubs himself, lecturing, and writing. His column in the San Francisco Chronicle ran for 56 years. In 1986 he was inducted into the U.S. Chess Hall of Fame.
The game itself is another character in this blend of personalities. Chess is comprised of so many exquisitely fascinating features: its age, its forms, and the hypnotic involvement it seems to provoke (all right – call it addictive). Chess clubs were popping up everywhere in that day, some even founded by Duchamp and Koltanowski. Every city they happened to visit needed a venue where they could find partners, although Koltanowski was known to have played against a machine – even an elephant (Ed. note: I din’t know elephants could play chess. Who won the game, Simone?)
Duchamp became obsessed with the game, all but giving up his vocation. He created several sets of chess pieces, which sold successfully . (Although from a well-heeled family, he needed to scrounge for a living like everyone else in Greenwich Village.)
Chess pieces are objets d’art in their own right, but one can also appreciate the artistry that goes into the design of a pipe. A smoker’s pleasure comes from the shape and material – the heft if you like, of the pipe, as much as from the tobacco a smoker uses.
The specific pipe that is the star of the book is a rather chunky, boxy, artifact. It must have been one that Duchamp particularly liked because the author describes the giving of it to George as a gesture of regard, meant to mark the former’s appreciation of their friendship.
If this book were a book club choice, there would be terrific areas for discussion. Every aspect, the times they played chess together, other encounters and journal entries on the part of these two men and their friends, give such nuanced glimpses of character and personality. Chess is – remember, a game of thinking and strategy, although smoking was often a complement to chess in the past: Smoking while studying the board, smoking while visualizing moves, smoking, thinking, imagining, and finally just smoking.
Meanwhile, life, including two world wars, was whipping around the two main protagaonists in the book. Celia has a previous book (2002) entitled “Surrealism and the Sacred: Power, Eros, and the Occult in Modern Art”. That information is important to bear in mind because of the mystic quality the author perceives between people and objects and time, in other words, in existence.
Another Winnipegger, Irwin Lipnowski, has an essay towards the end of this book. Irwin, as we know, is a chess champion in his own right. Here, he speculates on the future of chess cafés in an era subsumed by technology.
Something else interesting about chess: As the Parshas on the last couple of Shabbats were about the naming of Beersheva, I decided to look up that Israeli city on line. Here’s what I came upon, from an article written in October, 2009: “With eight Chess Grand Masters calling Beersheva home, the city has more International Grand Masters per capita than any other city in the world.” Hmm!
“Duchamp’s Pipe, A Chess Romance” was launched via Zoom on November 19th, to an international audience. Celia spoke about her experiences writing the book with Ann McCoy, an artist and writer herself, and their conversation is now on YouTube – a worthwhile watch.

Volatility, Hit Frequency, and RTP: Why the Number Casinos Advertise Is the Least Useful One
The return to player percentage looks clean as a casino data point. It gives players a neat number, usually around 94% to 97% for many online slots, and that number feels easy to compare. A 96.5% game appears better than a 95.2% game. The problem starts when players treat RTP as a forecast for their next 50 spins or one evening.
You may find the RTP listed on slot pages on a leading online casino in Ontario, but the number only tells part of the story. Two games can share the same RTP and create different sessions: one may return small wins often, while the other may drain a balance before one bonus round changes everything.
The RTP Trap
Return to player (RTP) measures the theoretical share of total wagers a game returns across a very large number of rounds. In plain terms, a 96% RTP slot returns about $96 for every $100 wagered in the long run. That does not mean one player who deposits $100 should expect $96 back.
The trap sits in the word “theoretical.” RTP comes from the game’s math model. It works across huge samples, not personal sessions. A player can finish far above that percentage, far below it, or with nothing left after a short run of poor results.
Is it useless then? No, RTP can still help. It gives a baseline cost of play. Lower-RTP games cost more on average than higher-RTP games. Still, once a game passes a reasonable threshold, the next question matters more: how does it distribute that return?
Hit Frequency: The Number That Shapes Session Feel
Hit frequency tells you how often a game produces a winning outcome. This often misleads players because any win can count. A spin that returns $0.10 on a $1 bet may still count as a hit, even though the player lost $0.90 in real terms.
A game can feel active because symbols connect often, sounds play, and the screen keeps celebrating small returns. The balance may still fall. In many modern slots, “win” does not always mean profit on the spin.
Hit frequency answers one practical question: how much silence can you tolerate? Some players dislike long dry spells. Others accept quieter sessions because they chase bonus rounds or larger payouts.
The educational site Get Gambling Facts gives a useful distinction: RTP concerns the percentage of money returned over time, while hit frequency concerns how often a machine stops on a winning combination.
Volatility: The Risk Label Players Need More Often
Volatility, also called variance, describes how unevenly a game pays. Low-volatility games tend to return smaller amounts more often. High-volatility games hold more value in rare events: bonus rounds, premium symbols, multipliers, or jackpots.
Here is where RTP becomes less useful on its own:
- A 96% low-volatility slot may give modest returns and longer play from the same balance.
- A 96% high-volatility slot may burn through funds quickly unless the player hits a strong feature.
- A progressive jackpot game may look exciting, but it often places more value on rare top prizes.
The same RTP can hide very different risk profiles. Players who ignore volatility often blame the casino or the game when the session follows its math design.
Why the Same RTP Can Feel So Different
Picture two slots with 96% RTP. Slot A pays small wins on many spins, has a modest top prize, and rarely creates dramatic balance swings. Slot B pays less often but offers a large max win and volatile bonus rounds. The advertised return matches, but the experience does not.
Slot A may suit a player who wants a slower bankroll drop and more regular feedback. Slot B suits someone who accepts sharper losses in exchange for a shot at a heavier payout.
A Better Way to Read a Slot Page
Most slot pages give players more clues than they notice. The trick is to read the details together rather than chase the highest percentage.
Start with RTP. If two games look similar, the higher number has better long-term value. Then check volatility. If the game uses terms such as high, very high, or extreme variance, lower your bet size or expect shorter sessions. Next, look at the paytable. A huge max win usually means the game saves a lot of its value for rare outcomes.
A sensible pre-play check looks like this:
- RTP: What is the average long-term return?
- Volatility: How rough can the session become?
- Hit frequency: How often will the game show any wins?
- Paytable: Where does most value sit?
To Conclude
Casinos advertise RTP because it looks objective, tidy, and easy to rank. Players should read it, but they should not give it more authority than it deserves. For long sessions, volatility may matter more than a small RTP difference. For comfort, hit frequency may explain the feel better than the payback rate.

The Popularity of Simpler Slot Games in 2026: Review From Casino Online CrazyTower Experts
Online casinos now fill their libraries with numerous video slots that have dozens of functions, long bonus rounds, complex mechanics, and so on. Interestingly, despite this huge range of modern options, many Canadian visitors at sites like Casino Online CrazyTower here https://crazytower.com/ca/ no longer want complicated gameplay that requires constant attention and long explanations.
Simpler slots now attract a wider audience because they save time and create faster sessions. So, let’s figure out why this change happened and reasons for the popularity of simpler machines.
Why Many Players Are Returning to Basic Gameplay
Modern websites like Casino Online CrazyTower pushed complex video slots for years, but many people now prefer classic formats again. Simple gameplay has fewer interruptions and is simpler in terms of budgeting, which is important when you gamble for fun.
These are a few potential reasons explain why simpler slots became popular again in 2026:
- Faster rounds. Symbols appear quickly, and rounds continue without long animations or extended bonus sequences.
- Easier controls. Most classic slots have simple menus and familiar layouts that don’t confuse new visitors.
- Smaller feature lists. Simple slots usually have standard wilds, scatters, and multipliers instead of dozens of random mechanics.
- Better session flow. People spend more time on gameplay instead of reading explanations about symbols and special functions.
- Lower visual pressure. Simpler slots use calmer designs and shorter effects that don’t overload attention.
Classic gameplay also suits mobile devices better because shorter rounds work well on smaller screens. Plus, many visitors now prefer games that start instantly and explain their mechanics within seconds.
Features That Make Simpler Slots Appealing
Simple machines at Casino Online CrazyTower and similar websites continue to attract attention because they have a high gameplay speed. Many classic titles also replicate older casino machines that people already know from physical casinos.
However, these aren’t the only factors that attract gamblers. So, check out this list:
- Short bonus rounds. Free spins and multipliers finish quickly instead of interrupting gameplay for several minutes.
- Common and standard paylines. Traditional layouts help people understand payouts without long explanations.
- Faster loading times. Simpler graphics reduce waiting time on phones, tablets, and older computers.
- Stable gameplay pace. Long cutscenes and constant pop-up notifications don’t interrupt the session.
- Traditional themes. Fruit symbols, bars, sevens, and classic casino designs still attract large audiences.
- Smaller menus. Important information appears immediately without complicated tabs or hidden sections.
Modern video slots often contain too many mechanics in a single game. Developers now combine expanding reels, random modifiers, mission systems, tournaments, and multiple bonus levels in one title. Many visitors lose interest because gameplay turns repetitive and overloaded with constant interruptions.
Compare this to a session when you get results immediately and aren’t interrupted. These still have free spins and even mini risk games, but not as loaded as innovative titles.
Conclusion
Simple slots usually create better replay value because people understand the mechanics immediately. Common and standard gameplay doesn’t cause frustration and allows faster decisions during casino sessions.
Many classic slots also function better during short breaks because rounds finish quickly without long bonus interruptions. That’s why simpler slots became popular again at many casinos, including Casino Online CrazyTower and such.
