Dealer: South Vuln: None

1. Playing strong No Trump so rebid now showing 13/14 balanced

This hand is real touch and go and you have to take advantage of a non Club lead and a good layout in the Heart suit.

After winning the first trick with  the ♠10 immediately play a Diamond and more diamonds. The opponents take the third round of Diamonds and persist with Spades which you win in dummy, While in the dummy, take the Heart finesse (making sure you do not cash the winning diamond at this point as you need it as an entry later on (hopefully) for  13th Heart.

The heart finesse works and West does not cover the Queen. 

Now play the Heart Jack and when East covers, duck it thereby ensuring the safe hand wins and your club king in dummy is still safe as East in this situation is the safe hand and we do not mind East getting the lead.

East gets off lead with a spade which you win.

Now play the Ace Hearts delighted to see the remaining hearts breaking kindly 3:3.

You now go over to that precious Diamond Queen to cash the winning established  Heart.

You eventually made 3 Spades, 3 Hearts and 3 Diamonds unlike my partner who managed to go 3 down despite the friendly defence,

(Perhaps West might lead the ♣Queen next time.)
