Enter North-South suit holding and click Analyze
North Enter actual cards, or x if insignificant (presumed lowest unspecified). Example: AJTxx. Enter Souths cards in the box below.
Length in suit Adjust if you know about E-W lengths in the suit entered. If East showed a balanced hand, set East Min 2 and Max 5.
Vacant spaces Adjust if you know the exact E-W lengths of other suits. If West has 6 known and East 2, set to 7 and 11, respectively.
HCP in suit Adjust if you know about E-W HCP in the suit entered. If your holding lacks the ace and you know West has it, set West Min 4.
Free HCP in hand Adjust if one opponent is known to have a stronger hand, or more specifically, a greater number of unaccounted HCP. Set both West and East to their portion of free HCP. Results with this setting are not exact but a close approximation, because it depends on which specific cards comprise the E-W HCP.
