What is the meaning of "A blonder hand might have turned the game even at that point"

You had me confused..... the text reads, "One fierce blow at the unsuspecting horseman at his side, one cry to his French troops, one desperate charge upon the unready lines before him, and these rebellious Barons might rue the day they dared to thwart his plans! A bolder hand might have turned the game even at that point. Had it been a Richard there! the cup of liberty might have been dashed from England’s lips, and the taste of freedom held back for a hundred years."

Bolder infers someone more daring..... willing to take risks.
