You got to 4♥ after your partner bids 3♣ – fourth suit forcing to game – and discover that your partner has a singleton heart. West leads the ♣A and then the ♦4. How are you going to make it?

If you look at the hand you can count five sure tricks with hearts, three with spades and then you have the ♦A. Finding the tenth trick is tricky, you must promote your ♣Q or the ♦10 to become a winner.

While playing this hand you must also bear in mind transportation as your only entries to dummy are the ♥K and the ♦A. You take the second trick with the ♦A and lead a small spade, take two tricks with the ♠K and ♠Q and use the ♥K to get back to dummy.

Next crossroad is the choice whether to lead the ♠A and discard the ♣10 or to lead a small spade and ruff taking the lead back to your hand to start pulling the trumps.

Tempting as the thought is to discard your singleton club you might need it to take down the ♣K or the ♣ J.

So you lead the ♠9 from dummy, ruff and start pulling the trumps playing ♥AQJ one after another. From dummy you discard two diamonds and a small club.

East discards the ♣4 in the last trump trick.

Now you must choose what to lead, clubs or diamonds.

West led the ♦4 after winning the first trick with the ♣A indicating length in diamonds and as East played the ♦J in this trick. Therefore it can be concluded that the probable distribution of the remaining diamonds is such that West has ♦Kxx and East the ♦Q.

If you lead a small diamond, East wins the trick with the ruutu Q and has to lead clubs enabling you to take two of the last four tricks.
