After losing to a Kings Gambit of Spassky in the Mar del plata tournament in 1959, he published the following article, which is regarded as the most read article on an opening.

Quoting the initial paragraph:
“The King's Gambit has lost popularity, but not sympathy.Analysts treat it with kid gloves and seem reluctant to demonstrate an outright refuatation."The Chessplayers Manual" by Gossip and Lipschutz, published in 1874, devotes 237 pages to this gambit without arriving at a conclusion. To this day the opening has been analyzed romantically – not scientifically.

Moderns seem to share the same unconscious attitude that caused the old-timers to curse stubborn Steinitz:"He took the beauty out of chess."

To the public, the player of the King's Gambit exhibits courage and derring-do. The gambit has been making a comeback with the younger Soviet masters, notably Spassky (who defeated Bronstein, Averbach and myself with it).

His victories rarely reflected the merits of the opening since his opponents went wrong in the mid-game. It is often the case, also, as with Santasiere and Bronstein, that the King's Gambit is played with a view to a favorable endgame. Spassky told me himself the gambit doesn't give White much, but he plays it because neither does the Ruy Lopez nor the Giuoco Piano.”
