Three prisoners have a brief strategy meeting, and then are not allowed to communicate.

Each night one of the three has steak for dinner, while the other two have fish tacos. Also each night, each of the three prisoners votes for one of the following two options:

1. All of us have had steak at least once.
2. Don't know yet.

If a majority go with option 2, nothing happens that night. If a majority go with option 1, then they are set free if they are right, and executed if they are wrong.

What should their strategy be?
