Echoes on the White Squares- from Chigorin to Gufeld
I beg to be forgiven; I am from another era. Started playing chess in 1972, when the Spassky-Fisher fever was on. wanted to be World Champion; would study sometimes 6 hours a day!
Was champion of my country at 19; then, in a Zonal Tournament for the World Championship, "failed" to get the IM title, but in the process, played the best game of my life, and learned that a chess career was not my destiny.
Fifty years later, I still love chess, maybe too much. I find chess incredibly relaxing; it is a human and intellectual pursuit. The aesthetics of the game are more important for me now than winning and losing (except when I play for the Reykjavik Team in the Spring; I really do not want to embarrass my friend who invites me to play for the team!).
Being form the old guard, I prefer actual physical books to e-books; there is something magical about opening a favorite book on a random page, and finding something great, something good, something immortal. Right now, my personal chess library numbers over 200 chess books; mostly game collections.
One of my best chess books is almost impossible to find. It is so good, it has been bought out by people who know, who can tell when something is good. I am talking about Jimmy Adam's book on Chigorin:

One of the things that makes this book immortal is the collection of annotators to some of the games. You might get comments by Chigorin himself, and by some of his contemporaries, such as Lasker, Potter, Schiffers, Tarrasch....and by 20th Century Masters such as Botvinnik, Panov and Romanovsky, among others. How is this possible? Well, towards the end of the 19th Century and beginning of the 20th, one of the ways chess players made money was to write chess columns for newspapers, and Chigorin's games were so rich in content, in new ideas, that they were featured in chess columns, which Jimmy Adams tracked down in this wonderful piece of work.
But what about the "Echoes on the White Squares"?, you may ask.
Well, before the two examples which show an echo theme, I will recommend another book,
"My Life in Chess", by Eduard Gufeld. He writes with a lot of human warmth.....

No idea if the book is still available. A jewel of a book, indeed!
Ok, so here are the two examples. The first is the game Bagirov-Gufeld, which Gufeld considers to be his own immortal game. Gufeld plays the King's Indian Defense, and Bagirov plays the Saemisch Variation, castles long, and launches an attack......Gufeld employs the Panno System (with ....Nc6, Rb8, a6, Bd7 and b5), and launches a counterattack.
I will post the moves, and then a variation at the end, which contains the theme......
This is a beautiful motif.....but imagine my surprise when, perusing the Chigorin book, I found this game, in which a similar motif could have occurred.....
Two different opening systems, 76 years apart, but with some common themes.....opposite-side castling, exposed White King, and a possible checkmate on b5 with the black Queen..... Enough for me to notice!
Sorry, I do not have time for more now. Enjoy....
Peace.
