A dubious choice by the future 11th worldchampion in the history of chess. Even if thismove is sufficient for a draw, it in any case

makes play more difficult for Black in the

future. Right at the start of the search for a

move, a goal must be formulated which isbased on an evaluation of the position. Here

Fischer over-estimated his position and set

himself an over-ambitious goal.

After 29...Ke7 30.h3 (30.Ke4 f5 31.Kd4?Lh2+) 30...e5= followed by 31... Ke6

Fischer had no problems in drawing.Eine fragwrdige Wahl des spteren 11.Weltmeisters der Schachgeschichte. Selbst

wenn auch dieser Zug zum Remis ausreicht,

es erschwert in jedem Fall das weitere Spielfr Schwarz. Ganz am Anfang jeder

Zugfindung muss ein Ziel aufgrund einer

Stellungseinschtzung formuliert werden.

Hier berschtzte Fischer seine Stellung undsetzte sich daraufhin ein zu ambitioniertes

Ziel. Mit 29...Ke7 30.h3 (30.Ke4 f5

31.Kd4? Lh2+) 30...e5=, gefolgt von31...Ke6 konnte Fischer problemlos

remisieren.30.g3 h530...Ke7!? 31.a4 (31.Ld2 Kd6 32.Lb4 Ke5
