Richard Reti (1889-1922) is one of my favourite chess personalities. He is a well known chess player, but maybe not so well-known as Alekhine, Capablanca, Anand, Carlsen, etc.
This thread is not, however a biography about Richard Reti, but an account of some of his achievments. One of his most favorite endgame studies is this:
Richard Reti was also a great opening player. He made one of my favorite openings as white the RETI opening.
This game has one of the most premature errors in the history of chess. The great Tartakower blunders a mate in 3! Can you find it?
Also see this one, looks like another Réti fan.
