"Chess is like a language. The top players are very fluent at it. Talent can be developed scientifically, but you have to find first what you are good at."

🔸 Viswanathan Anand

From "The Historic New Orleans Collection":

“The magnificent American master had the most extraordinary brain that anybody has ever had for chess. Technique, strategy, tactics, knowledge which is inconceivable for us; all that was possessed by Morphy fifty-four years ago.”

🔸 Jose R. Capablanca

Here is the only problem attributed to Morphy: White play and mat in 2
