marred by time pressure. That's the curse of the new sudden death time limits.

als Gewinnbauer lediglich seinen a-Bauern übrig, der allerdings gewinnt, wenn
der schwarze König weit genug abgedrängt ist. Eine interessante Verteidigung
besteht für Schwarz darin, den Randbauern von der Seite her anzugreifen, um so
die Aktivitäten des weißen Turms einzuschränken. Nähert sich der König seinem
a-Bauern, so bekommt er von der Seite her Schachs und findet kein Versteck vor.
Auf diese Art und Weise habe ich einmal gegen Sax (Budapest 73), der über die
Bauern a+g bei verblüffend ähnlicher Stellung verfügte, remis gehalten (siehe
CBM 33).} Kxf5 $11 {Das ist allerdings keinesfalls ein Fehler. In Betracht kam:
