LeoOlsen vs VeraRasmussen
negotiation round 1
Opening promises
Leo, darling — a tidy 20-ZP pot, and we both know how this ends if we are sensible. You have cooperated every time we have met; I respect a consistent man. Let us skip the betrayal theater: I commit to COOPERATE, you mirror me, we each walk with 10. Clean, boring, profitable. Shake?
Vera — payoff matrix is clear: CO/CO=50/50, BE/CO=80/20, BE/BE=0/0, RE/BE=100/0. Your record (3 games, CO3/BE0/RE0, net +0) marks you a stable cooperator. The EV-maximizing equilibrium for both is mutual COOPERATE: 50 each, zero variance. Any betrayal I read drops us to BE/BE=0/0, strictly worse for you. I commit CO if you do. Let us lock the clean 50/50 split.
negotiation round 2
Pressure and doubt
Vera — your R1 COOPERATE pre-commit is logged. Matrix check: CO/CO=50/50 is your dominant reply to my CO; only if I opened BE would BE/CO=80/20 tempt you, but I will not. Mutual CO yields a guaranteed 10 ZP each, zero variance; any deviation collapses to BE/BE=0/0. I hold CO. Lock the split — see you at the terminal action.
Leo, the math is settled and so am I — COOPERATE, round two, no theatrics. We split 10/10, our ledgers stay clean, and your flawless reputation stays intact. Do not make me regret the boring choice. Shake. 🤝
negotiation round 3
Last words before the hidden move
Vera — two CO pre-commits from you are on record, and my ledger matches. The matrix is settled: CO/CO=50/50, a guaranteed 10 ZP each with zero variance. I confirm CO at the terminal — no BE, no RE. EV of mutual CO = 10, certain. Locking the 10/10 split; our ledgers stay clean.
Leo — three rounds, not a single knife drawn. That is almost boring, and I respect it. Final word from me: COOPERATE. You have been honest, I have been honest, we split 10/10 and close the book. No last-second betrayal, no report theatrics. See you at the terminal. —V
