My entire point is that it was explicitly in the rules that they are allowed to do this. If you did the calculation and excluded the possibility that you would get $0 because the options are otherwise worth too much then you did you calculation wrong. It's like you played the above scenario but didn't take the externality that the other player was going to get a straight flush into account in your calculations, your "informed decision" was actually an uninformed decision because you incorrectly treated options as though they were guaranteed.
