The wording of your comment reveals your bias towards the other school of thought, Strong AI. But what is "true" intelligence? I don't think anyone has a clear definition of this, and in reality it's all just a philosophical quagmire.
An important distinction is whether mimicry is equivalent to "true" intelligence, or whether it should be treated as such, barring a better litmus test. With that in mind, taking a methodologically agnostic perspective of adequately reproducing behavior that is predicated as intelligence seems like a much more reasonable goal to me.
Strong AI wouldn't make same silly mistakes which people make all the time. So would the Strong AI need to be smart enough to play dumb to fool people? Because people are illogical, smart machines surely wouldn't be?
A Strong AI is by definition more intelligent than humans, so it could also deceive. No need to "be illogical", just playing along. In any case it's rather irrelevant, because presumably if there is a Strong AI, it would be so impressive that there is no need for a Turing test to prove it.
