Chp 33 provides more support for this take on chp 32. Draco & Hermione threaten to cooperate against Harry if he accepts traitors, Harry openly proclaims that he'll accept traitors and challenges them to cooperate, and Quirrell is surprised by Harry's response. This makes the most sense if Harry is thinking outside the game and seeing his tactic as win-win: either he gets Draco & Hermione to cooperate (win in life), or they fail to cooperate and he has an advantage in the battle (win in the game).
