Thanks for organizing this, here’s the pseudocode for my entry.
Robot 1:
Cooperate at first, then tit for tat for 42 rounds, then identify yourself by playing: [0, 1, 1, 0, 0, 0, 1,1, 1, 1], then cooperate if the opponent did the same, otherwise defect.
Robot 2:
Same as robot 1, ending with:
… otherwise tit for tat
Robot 3 (secret):
Same as robot 1, with a secret identifying sequence and number of initial ronds (you pick Isaac).
