Balanced hand
In the game of contract bridge, a balanced hand denotes a hand of thirteen cards which contains no singleton or void and at most one. Three hand patterns are classified as truly balanced: 4-3-3-3, 4-4-3-2 and 5-3-3-2. The hand patterns 5-4-2-2 and 6-3-2-2 are generally referred to as semi-balanced.
In natural bidding systems, balanced hands within specified high card point ranges are generally opened with a notrump bid, or rebid in notrump.
In the Netherlands, a bidding system called Saaie klaver that reserves the 1 opening for all balanced hands, has gained some popularity.Literature
