This is a moronic example on many levels. First of all, how did 9 BBs get into the pot by fifth and you're head up? Second, if you call to the river and she bets you'd be getting 13-1 on a call. There are very few players who I'd be sure weren't either overplaying a queens up or semibluffing a hand like pair + straight draw, or just flat bluffing that I could fold here. In general, Schoonmaker's stuff is pretty poor from a poker point of view. His basic point here, that you can read a passive player as having the straight often enough to make three betting with trips wrong is reasonable. But the idea that you'll be able to lock that read down so tight that you can fold getting 13-1 is a step too far in most cases.
