You are right, of course. But Frans finds it distasteful to try to get a point
by playing on Piket's time (six minutes vs 61 for Fritz). Naturally Fritz itself
would have played on, since it was displaying a substantial plus. And with the
knight it would have created enough complications to occupy the opponent for
more than six minutes. But apparently that's not the way Frans wants to win
games. His commentary after the game was typical: "The result is okay. Fritz
didn't play any crazy moves, I'm very pleased".
