New Canadian Bridge
East put up the ace to return the heart jack as South won the king, discarding a spade from the table. Five club winners came next on which West had to find three discards. He parted with a spade and a diamond but was pressured by the last club. He elected to throw a heart but now South could play a spade, driving out the ace. West could cash two hearts but nine tricks were home, N-S +400. A second diamond discard will result in ten tricks when the top diamonds drop the queen. The early play revealed that West needed the queen of diamonds for an opening bid and South was confident of success when clubs divided 22.
North's leap to three hearts was a splinter showing a singleton heart, excellent club support and a strong hand. This action asked South to make an informed decision regarding the final contract. South had no desire to play in clubs and chose to advance to 3NT with a heart stopper. The minor suit game is icy because trumps break 2-2 where the defense scores only the major suit aces.
East should offer a heart raise over the double which will put up a roadblock that will be difficult for the opponents to overcome. After two passes, North will re-open with a double but it is far from clear that game will be reached.
