On hands like the one shown, it is important not to start with a strong two bid. These use too much space and make it difficult to express your shape. Opening one spade is ideal. If partner has enough for game, they will respond to a one bid and, if they pass, the other side will usually back into the auction. As it happens, partner responds 2C showing 11+ HCP and four or more cards. Now the jump rebid of 3S makes the auction forcing to game. It also denies a second suit since you would bid another suit if you had one. Since partner knows you don’t have a second suit, it is clear that the 4D bid is not an attempt to find another fit and so it must be a cue bid. This suggests slam interest. It is not clear which twelve tricks are available but the club suit will probably provide them. After checking there are not too many top losers, South bids the slam. Rather than making an adventurous lead from a red suit honour, West decides to make a quiet trump lead. This is safe since he knows that any missing trump honours are onside and declarer will always pick them up naturally. Declarer can count eleven tricks comprising six spades, two hearts, two clubs and one diamond. Most club players would draw trumps and take the heart finesse and make or go down depending on the position of the KH. Better players will see that there is also a chance that the clubs are 3- 3 and that the thirteenth club will provide a heart discard instead of the risky heart finesse. This is only a 36% chance but you can try for the 3- 3 break and, when it fails, the heart finesse will win 50% giving a 68% total chance which is much better than the heart finesse alone. Thus, declarer should draw trumps, play the heart ace and then ace, king and another club. If the clubs are not 3- 3 ( or QJ doubleton), win the return and take the heart finesse. The key is that two chances are much better than one but you must try them in the correct order!
