A double jump in a new suit on the second round of bidding, showing a fit with partner's suit and a shortage in the fourth suit. The last bid in each of the following is a fragment bid:

1C - P - 1H - P 1C - P - 1H -P 1C - P - 1H - P

3S 1S - P - 4D 1S - P - 4C

The fragment bidder usually has two or three cards in the fragment suit, and must have a singleton or void in the fourth suit (clubs in the second example above).
