This is a game of movei against Ufim in the nunn games of Heinz and I am trying
to analyze if movei missed a win.
It seems that the position is a draw after 68.gxf6 but I am not sure if there
was a winning alternative because inspite of the fact that white has a pawn and
has a piece advantage I do not see way for white to make progress.
