BIDDING: This North-South partnership uses the Lebensohl
convention to deal with interference over their 1NT openers. The
immediate cue bid of 3H is a form of Stayman showing game going values,
a four card spade suit, but NO heart stopper. If South had a
heart stopper along with four spades, he would first bid 2NT to relay
partner to 3C and then bid 3. If North did not hold a
heart stopper, he would start bidding his suits up the line to find a
fit.
PLAY: East led a low heart and North had an easy eleven tricks:
four spades, one heart, five diamonds, and one club.
The Lebensohl convention has other uses so be sure to research it
completely before adding it to your convention card.
