Ultimately you either interpret "superintelligence" as being sufficient to predict your reaction with significant accuracy, or not. If not, the problem is just a straightforward probability question, as explained here, and becomes uninteresting.

Otherwise, if you interpret "superintelligence" as being sufficient to predict your reaction with significant accuracy (especially a high accuracy like >99.5%), the words of this sentence...

And the twist is that Omega has put a million dollars in box B iff Omega has predicted that you will take only box B.

...simply mean "One-box to win, with high confidence."

Summary: After disambiguating "superintelligence" (making the belief that Omega is a superintelligence pay rent), Newcomb's problem turns into either a straightforward probability question or a fairly simple issue of rearranging the words in equivalent ways to make the winning answer readily apparent.
