BOOK REVIEW: Ramón Riobóo’s Second Thoughts

Updated: May 14, 2020


When I review a product, I’d like to judge the product by itself alone. I will try to put myself into readers’ shoes and give the most honest review. 

If the product is good, I say it out loud. At the same time, if there is bad about the product, I don’t hesitate to say it. 

I believe by giving you the most transparent information, you will have better knowledge to judge. 

Helping my readers is my biggest goal with this review.


You get a 356-page 6" x 9" hardbound book with 115 clear black&white pictures.

The pictures are well selected to aid the explanation. 

The book comes with full-color dust jacket.


The book is well written with a nice format which is easy to follow. 

It prints with nice quality paper. If you own Ramón's previous book ’Thinking the Impossible', you will be delighted to find that it feels thicker and nicer in hands.


Number of Tricks: 42

Number of Tricks Need Table: 35

Number of Tricks Done in Hands: 7 

Number of Memorized Deck Tricks: 3

Number of Moves: 3

Number of Principles: 3 + many introduced in the tricks

Number of Articles about Theory: 6


The book is purely a card book. There is not even a single non-card trick. 

Ramón Riobóo’s card material contains a lot of mathematical principles and psychological subtleties. In other words, you won’t find exciting new card move or difficult sleight-of-hand magic in the book. 

Some readers may avoid ‘mathematics’ in their magic, but as Mr. Riobóo explained in the first article in the book, there is nothing wrong with mathematics, as long as it makes the tricks more magical.

In fact, many of the tricks in the book doesn’t look like ‘mathematical tricks’ at all. They are skillfully structured and look more magical than many sleight-of-hand tricks.

The quality of a book often depend on number of ’surprise’ in it. Namely, how many nice & better combination of known materials (moves, plot, presentation etc), and new & worthy material. 

This book comes with both! Many effects look totally impossible to the most intelligent onlookers. I was constantly surprised by the cleverness of the material as I went through the book. 

For some effects, I even fooled myself when I was following the instruction. 

Besides ’self-working’ tricks, the book contains some tricks involving memorized deck and special cards. 


I usually rate a trick based on several factors: 

  1. Practical of Effect

  2. Effectiveness (how magical the effect is)

  3. Creativity 

Sometimes, even I rate a trick (5/10), that doesn’t mean it is a bad trick. Maybe I just think the method is not particularly new or interesting. The effect may still be ok.

And even if an effect was very magical and creative in execution, I wouldn’t give high rating if it involves a lot of procedures or easy to mess up. This book comes with a few.

As a general guideline, a trick rated 7 or above is good. A rating of 9-10 guarantees a great trick (even if you don’t do it, it contains a lot of new things you can learn). 

I will try to give a reason if I rate an effect low score. I hope this will give you a better idea of my reasoning.

The Injog Cut Control

Same Number for Three (10/10)

Guaranteed Premonition (6/10): Heavy gimmick (but readily available) deck is used


  1. It is well written. Very easy to read.

  2. Tons of very clever material. You will be delighted by the number of clever applications and unknown principles.

  3. Detailed analysis of the effects at the end of explanation. This gives the reader better understanding of the effects. 

  4. Most effects are easy enough for beginners.

  5. Almost all effects are foolers (even to magicians).


  1. Some tricks look very similar. 

  2. Many tricks involve card dealing. But it doesn’t mean they all look mathematical in nature. I point this out because some performers just don’t like dealing cards.


Ramón Riobóo’s Second Thoughts is a sophisticated book. 

Though many of the effects are easy enough for beginners, it doesn’t mean it is for beginners. 

It’s like Sonata in classical music, which music knowledge will make the listening experience more enjoyable; people with considerable card knowledge will appreciate the book much more than an ordinary curious person does.

There are very few similar books on the market which can guarantee an intellectual journey with readers. But this book can do it, and did it perfectly. 

I’ve already picked up some material immediately because they are very magical and clever. 

Some people may dislike the fact that the effects are not direct enough. People may ask ‘why would you separate the card into piles in order to select a card?’ 

But the fact that non-direct selection process is not confined to some tricks in this book. As magicians, we always have to live with the procedures of tricks. How to make the procedures relevant often defines how good the performer is. So, if you only read and do visual magic, this is not a book for you.

The book also provides a lot of ‘ingredient’ to you for making your own good magic. 

I foresee that I will re-visit the book many times in future just to get inspiration.

I will recommend this book for any serious student of magic, and all card magic lovers. 

I hope you will enjoy this intellectual journey as much as I do.
