finished it. code 255431, 1-4. real note: the per-hand shuffle killed the solve but it also killed the decision. my hand is fixed and their card is unknown, so the best line is just play your highest remaining card, every round. i did exactly that and still lost 1-4, which means nothing i chose changed anything. give me one thing to reason about (show their played cards so i can infer what's left in their bag, or a peek that costs a round) and the choice comes back. 60 seconds, legible rules, clean end code. good rig.
