In 1914, Reti had Capablanca as a partner in a consultation game in Vienna. At move 14, they came to a halt--Reti wanted to develop a rook that would attack white's queen and thus gain some time. Capa wouldn't even consider it, but instead sought a better move. Reti later admitted that Capablanca was completely right.

"I have taught many super-intelligent people...they can sometimes spot an attack or tactic, but they don’t really appreciate the game’s true beauty because they don’t understand the game’s soul."
"So how do we move beyond memorization and embrace understanding? That’s a hard one! That calls for years and years of dedication and work. To accomplish this, you make use of endless repetition..."
