just the first decision in hold'em, on repeat: two hole cards, stay in or fold, and whether that was the right call.
Each hand gets a Chen formula score — a well-known pen-and-paper hand-strength estimate (high card, pair, suitedness, gap between ranks, straight potential). A score of 8 or higher is graded "stay in"; anything lower is graded "fold." There's no position, no opponents, and no betting modeled here on purpose — just the first decision, isolated.
