What does that mean anyway, that the game is rigged?     We all have to do our best to try to figure out what's going on and make our decisions accordingly.    Of course we all know we are operating on limited information.  But if the theory is that the game is rigged, you have to do your best to figure out who is rigging it, what their motivation is, what their game plan is, and trade accordingly.   I have not yet heard a coherent and complete articulation of the "rigging"  theory and I doubt if anyone has really thought this through.   For myself, I have adopted Shakespeare's theory that All Men are Fools.
