abstract:The Grand Slam Force is a bidding convention in contract bridge that was developed by Ely Culbertson in 1936. It is intended to be used in cases where the combined hands of a partnership are so strong that a slam (winning at least 12 tricks) is a near-certainty and a grand slam (winning all 13 tricks) is a possibility.
Thomas warned Welsh rugby it could take as long as it took England which could force respected coach Gatland, who guided Wales to the GrandSlam in his first Six Nations campaign, to consider his own future.
