Réti endgame study

The Réti maneuver is named after Richard Réti chess motif. A king approaches by pulling along a diagonal two goals at the same time, forcing the achievement of one of the two. The maneuver is due to the peculiarity of the checkerboard geometry, that the path of a king on a slope just lasts as long as a straight line.

The maneuver was named after RETIS famous study. It is well known among chess players, because it is seen as relevant to practice and aesthetically challenging. The idea of the study contradicts the conventional wisdom: "You can not chase two rabbits at the same time, otherwise both will run away ."

Arrangements of the theme by Réti

The requirement of RETIS study from 1921 looks at first glance from unsatisfiable, since the white king the black farmers can not seem to catch up, the black king the white farmers but already. So the white king must pursue two goals simultaneously:

• Support their own farmers
• Intercept the opponent's pawn

If the black king with KB6 approaches the white farmers, then the white king wins a train time to approach the square of the opponent's pawn. On the other hand -drawn black only his pawn forward, then the white king has enough time to support their own farmers and peasants both transform in the same pair of trains in a lady to. The chess master and author Savielly Tartakower praised RETIS study as " squaring the circle ".

Solution:

Or 2 ... h4 - h3 3 Kf6 - e7, and the King helps his peasants to collect the same time with the black.

That's the punch line. White now reached either time his peasants, or he catches the black pawn off after 3 ... Kb6xc6 4 KE5 - f4

The farmers are simultaneously move - draw.

This alternative version of Réti itself is almost more amazing than the first version due to the material preponderance of black. White plays first Kh5 - g6 and holds in all variants draw: 1 ... Ka 6 - b6 ( 1 ... h4 h5 2 Kxg7 3 Kxf6; 1 ... f5 2 Kxg7 f4 3 Kf6 f3 Ke6 4 ) 2 Kg6xg7 h6 - h5 ( 2 ... f5 f4 Kf6 3 4 5 Kd6 KE5 f3 ) 3 Kg7xf6 Kb6xc6 4 Kf6 - e5, together with a draw.

Studies by other composers

Although the maneuver occurred already in this much older study, it was named after Réti because his study was much better known. Here appears white on the train to have to force a draw by perpetual check, for how should farmers be stopped? However, it helps the Réti holds: The white king is his tower on the queenside to subsequently conquer g3 farmers!

This processing appears to be even more difficult to solve than the study of Réti because Black still has a runner. The paradoxical approach is to sacrifice the first two tempos to push the opponent's pawn forward, where it can then be intercepted by a Réti maneuver. solution:
