She knew who he was through her Party connections, and immediately let him in. It was Trijntje who went to the door at his knock. They were of similar mind on another matter too: when Frans van der Wiel showed up at their front door-tall and slim, and wearing a fedora and long wool coat over a jacket and tie-both could appreciate his movie-star looks.

When Truus found a forced sequence of moves that won a checker, the program would remember the conditions necessary for the sequence to work. One of Truus' novel features was the extensive use of tactical patterns in the evaluation function, and its ability to learn Draughts tactics.
