| rowspan="2" | The '''Réti Endgame Study''',<br/><br />
composed by [https://en.wikipedia.org/wiki/Richard_R%C3%A9ti Richard Réti] and published in 1921 in ''[https://en.wikipedia.org/wiki/Bernhard_Kagan Kagan's Neueste Schachnachrichten]'' <ref>[https://en.wikipedia.org/wiki/R%C3%A9ti_endgame_study Réti endgame study from Wikipedia]</ref>, demonstrates how a king can make multiple threats, and how it can take more than one path to a given location with the same number of moves. White to move and draw!<br />
<br />
At the first glance it seems that White has no hope. His king is far [[Rule of the Square|outside the square]] of the black pawn and further has a long way from supporting his own pawn with the opponent king inside its square.<br />
<br />
But the white king threatens to support his own [[Passed Pawn|passer]], while simultaneously coming closer to the black passer's pawn square. While the black king will have to spend two [[Tempo|tempi]] to stop the white passer from [[Promotions|queening]], this is the number of tempi the white king needs to gain in order to get into the square of the black passer. <br />
<br />
Inside a chess program's [[Evaluation|evaluation]], a too "rough" [[Rule of the Square|rule of the square]] implementation with huge "winning" scores will fail badly here, despite [[Search|search]] with [[Transposition Table|transposition table]] will solve Réti's study quickly, not to mention [[Endgame Tablebases|tablebases]]. <br />
