New Canadian Bridge
South won the ace, drew trump and successfully passed the queen of clubs when East declined to cover. However, there was no way to avoid the loss of a club and a spade trick, N-S +650.
3NT will yield only ten tricks when West begins with the king of spades but North judged to employ Stayman since he did not hold a perfectly balanced hand.
North declined to try for slam when the 4-4 heart fit was uncovered. He could have disclosed some slam interest by rebidding two spades which could not be natural according to their methods. This continuation would function as a balanced hand slam try with hearts agreed. South owns a maximum but the pancake pattern is not an asset and he is liable to sign off at game Slam is a poor proposition where declarer must avoid the loss a club for success. The addition of the ten of clubs to either hand would result in twelve tricks as long as the club king was onside.
Some partnerships would play that North's two spade continuation would reveal four spades with a hand of invitational strength. In their methods, the two club response does not necessarily promise a four-card major. Therefore, a 2NT rebid by North would deny four spades where a direct raise to 2NT would function as a transfer to diamonds.
