At
 the end of 2017 a draughts player asked me to have translations of some
 of my Spanish books that deal with the history of draughts. In one book
 I describe my draughts career by the side of Sijbrands and Wiersma, and
 in another book of two volumes I describe the life of the draughts 
world champion Maurice Raichenbach. I decided to start with the first 
book and  add some information about my business life in Spain. With 
that schoolteachers become aware of the great benefit that draughts has 
on the mind of children and their future business possibilities. 
There
 are not many biographies of draughts players and the books there are 
usually deal with the game. It is clear that I did not want to write 
them in Dutch, because there are many books about these players in the 
Netherlands and I cannot teach them anything. They know much more than I
 do. It is much more difficult to see Spanish texts about them and that 
was the reason why I wrote books in Spanish about Amadou Kandi, 
Woldouby, Maurice Raichenbach, Baba Sy, and others, because hopefully 
this way we can rescue future players in South America from obscurity. 
This
 time I will write in English so that the international players can also
 learn about some of the initial draughts lives of Wiersma and Sijbrands
 that today can be considered as history.
After
 the short introduction to the history of draughts in chapter 1 here 
come some words about the other content of this book. I wrote (in 
Spanish) the biography of Maurice Raichenbach, for several reasons. 
Firstly because with the "Raichenbach coup" against young Sijbrands I 
could have become immortal in 1963, as Harm Wiersma said. Secondly 
Raichenbach made the same victorious continuation in his game against 
Herman de Jongh, as Harm Wiersma did in 1963 against me in the Brinta 
Youth Tournament when he was just 10 years old. On the other hand 
Raichenbach was noted for his corner game on the board, as I used to 
play in 1965. Finally Raichenbach played to win tempi, as I also used to
 do in 1965. All these events are explained in chapters 2-6 which 
describe my short draughts career. I think that knowing Raichenbach’s 
game is necessary, since it now belongs to the theory that we must 
master draughts when we play it. 
Finally, I am attracted to Raichenbach, because this player left checkers to engage in successful business. 
During
 my many trips to Africa and South America I saw the way of life of 
their inhabitants. Checkers for them is a means of getting out of 
isolation. In Holland we already have many African players who make a 
living by playing in different draughts clubs. Draughts does not serve 
only to earn money, but also to increase our intelligence by 25%.
I
 hope my books on checkers will be useful for the young people of 
certain countries to come out of their isolation. In this short work the
 reader will realize that three children prodigies (Ton Sijbrands, Harm 
Wiersma, and Andreas Kuijken), among whom I was lucky to be, began to 
make life impossible for Russian draughts players. In this way Holland 
gradually regained its hegemony in draughts between 1972 and 1984. 
It
 is my desire that with my historical works about Woldouby,  Maurice 
Raichenbach, Baba Sy, other famous draughts players, and my short 
draughts career in Holland as expressed in this book readers become 
interested in the game of checkers, as was my case in the Netherlands. I
 met Baba Sy, visited many foreign countries, and witnessed other 
cultures to finally settle in Spain and believe me, I owe a lot to 
checkers.
The
 game of draughts deserves a more respectful place than it has and in 
this sense one should remember that draughts is more difficult than 
chess, as is explained in chapter 7 of this book.
Draughts
 players are very good at analyzing, tactics, strategy, intuition, 
fighting spirit, performance drive, thinking ahead, long-term planning, 
numeracy, patience, perseverance, creativity, concentration, logical 
thinking, imagination, and many other good qualities.  On the other hand
 draughts players are very creative. They are often able to discover a 
draw in a hopelessly standing position by means of threats or shots.  
All of that is explained in chapter 8.
I
 left draughts in 1965, but I felt myself playing draughts with the 
creation of products in various companies. For me the new products were 
like new variants in checkers. Draughts awakened my desire to master 
several languages and gave me a very competitive spirit, since I always 
wanted to be the best in the world with my products. I was co-owner and 
founder of an important company in the world of citrus extracts and 
among my wise friends and partners were two rectors of the University of
 Murcia. 
After
 the sale of this company in 1989 to a multinational I did the same job 
of competitive intelligence until 2012 (the year of my retirement) in 
other new companies, which nowadays are also on a high level in the 
world with their products. One of them was sold in 2015 to an Israeli 
multinational.Some of my business, draughts and history activities are 
explained in chapter 9. 
Since
 this book will be read by international readers and the term “King” for
 the most powerful piece in the game can give confusion to other 
speaking countries, I have dedicated some pages to the origin of this 
new powerful piece on the board in 1495, such as explained in chapter 
10. In Holland we have in the international draughts game a square on 
the board on which we place the “kroonschijf” (crown piece) and that is 
known in the English game as king-row piece. In chapter 11 I discuss its
 Spanish origin.
In
 chapter 12 there finally are some words about the Frenchman Dr. Diego 
Rodríguez (1940-2015) who gave me a lot of information by phone and sent
 me many photos of the draughts tournaments and players in the past. He 
was the ambassador of draughts in the Spanish-speaking world and a man 
of immense generosity.
I
 recommend this book to psycologists and all professionals who work with
 children as a source of knowledge and a challenge to think in new 
concepts.
