To some extent yes. But it depends on what function Bob implements. If Bob always playes Defect, Alice has no way of making him playing Cooperate (likewise, if he always playes Cooperate, Alice can’t make him play Defect).
Yes, but didn’t we already establish that Bob would always defect, because he had nothing to gain in either case, in which case he will defect no matter what Alice chooses? Or is Bob also a TDT-style agent?
