The absence of a fourth spade makes the overcall a safer option. A take out double of one major will usually show four cards in the other major. West with eleven points may try 2NT. A penalty double of 2C will also reap handsome dividends on this particular hand, as East can obtain a diamond ruff and score plus 500. Over 2NT, East has a natural bid of 4H and will lose just two clubs and a trump. 53 A Q 10 8 Q 87 A K 62 9 74 Q 82 6 532 J 974 K J 5 A 6 J 10 8 Q 954 A K J 10 6 K 10 9432 73 15 NT N 3 5 3 4 4 5 9 S 3 5 3 4 4 E 11 W Board 2 : Dealer East : NS Vulnerable Pass 1S Pass 2C Pass 2D Pass 2H* Pass 3D Pass 3NT North s bid of 2H* is fourth suit forcing to game.

If South had a stronger hand he could investigate a slam as he knows North has a good hand. 3NT will usually be the final contract. A club lead will see declarer win in hand, take spade finesse and likely end up with ten tricks..

As the spade suit is solid, it must contain the queen. In the play, West will win the likely heart lead and immediately play on diamonds hoping to establish the suit and discard dummy s losing clubs. South will win the second diamond and should switch to a club. It will be necessary for declarer to finesse.

That will help South in the play. If West leads Spade Jack, an immediate finesse will enable declarer discard a losing club. The finesse at this stage cannot cost as a losing club can be discarded later. As West has not led a club honour it is a reasonable assumption for declarer to believe that the club honours are split. As West has made a take out double it is also reasonable to place him with Diamond Queen. South can demonstrate his expertise by taking a backward finesse in diamonds and make three tricks in the suit. Leading the Jack is the winning play. If it is covered a finesse of the nine on the way back will lead to declarer making eleven tricks. 8 53 K Q K J 975 J 43 J 10 762 A Q 4 A J 862 10 53 10 6 32 9 7 K Q 86 K 9 9 74 A Q 84 A 10 52 10 NT N 2 4 2 6 11 S 2 4 2 E 3 2 13 W 2 2 Board 6 : Dealer East : EW Vulnerable Pass 1NT Some fearless West players will enter the fray with a bid to show both majors, despite partner passing and holding just six high card points. North can bid 2NT using the Lebensohl convention. In this instance, the bid of 2NT shows a hand where North wants to compete in the bidding. South, if East passes, will bid 3C and North now will compete with 3D. The effect of West s intervention is that N/S have reached their optimum spot in diamonds scoring 130 instead of 120 if West had passed. An immediate bid of 3D by North over West s intervention would show a stronger hand and be forcing to game.

This hand will be a tug of war between East and West. Some East players will have a system to show diamonds and a major.

The brave West players who go on to 3C will win the day. A winning spade can be set up by playing Ace King and Jack (running it if not covered) so that a losing heart can be discarded.

North has three small hearts but the club Ace is a valuable card and some North players will bid on to game. West will often lead the heart 5 (MUD Middle Up - Down).

The bid of 3C will normally show five spades as well as a club suit. North will lead the heart 7 2 nd highest from a poor suit. South, hoping it is from the nine, will return the heart queen at trick two. West s best play now is to duck a diamond. He will normally make ten or twelve tricks depending on his play of the spade suit. It will be important for South to keep his two spades when the diamonds are being run so as not to expose the position.
