Having reached the game zone, the next decision is whether to try for slam. Obviously you need enough values, but Chilli also has a number of absolute systemic requirements to bid a slam. You need:
| sufficient keycards | all five keycards (the four aces and the king of trumps) to bid a grand slam, and at least four of them to bid a small slam; a void opposite a holding with no ace and sufficient trumps is as good as a keycard |
| good trumps | the queen of trumps to bid seven, or six when missing a keycard; two extra trumps (guaranteeing a ten-card fit) will do instead |
| good methods | the right tools. |
