Bis hierhin ist alles bereits bekannt und bislang glaubte man, dass das
Endspiel unentschieden ist. Van Wely hat jedoch eine Neuerung parat. In den
naechsten Zuegen werden die Damen getauscht, wonach ein Endspiel entsteht, in
dem Weiss als Ersatz fuer die Minusfigur drei gefaehrliche Bauern amKoenigsflue
gel hat. Der Vorteil von 26.f3 gegenueber dem bisherigen Zug 26.h4 besteht
darin, dass Weiss mit g3-g4 ein weiteres Tempo fuer den Vormarsch seiner
Bauern gewinnt. Ich weiss nicht, ob nach Van Welys Neuerung Weiss sicher auf

{Before the Dutch championship I was in a very good form, winning almost all
the tournaments where I was playing. And having prepared well for this
tournament I was hoping to win the championship. The reality came different, I
was getting winning positions only to draw them. Thus, I just gave 1,5 points
as a present to my opponents. This game against Jan Werle is my win from the
Championship. Who would have thought that I would win only 1 game?!} 1. e4 e5
