This calculator evaluates balanced hands to determine if they should open a strong 1NT (15-17 points).

  • Enter a (semi)balanced hand and hit "Calculate" when done.
  • Tens ("T" or "10"), nines and eights are evaluated, so include them if desired.
  • Unsorted suits like "342" instead of "432" will not be recognized.
