The contract is 7 Spades in the south and the opening lead is the
king of diamonds.

You have twelve tricks off the top and have to find one more trick.

South reaches seven spades, and there is apparently an inescapable heart loser.  Before reading any further, see if you can figure out a way to make the grand slam.  (Yes, you may look at all four hands.)

Most declarers give up on this hand.  They go down one because they assume the contract is impossible.  Actually seven spades is quite a good contract, as it will probably succeed with a normal 3-2 trump break.  But it requires a little mental gymnastics.

Imagine that you get up from your South chair, walk around the table, and sit in the North seat.  Now, pretend the North hand is yours and South is the dummy.  You will be pleasantly surprised at how much brighter things look from this angle.

Although your trump holdings (the J 9 8) is not pretentious, it's good enough to draw the five outstanding trumps, provided they break 3-2.  Your three diamond losers can all be ruffed in "dummy."  And best of all, your two heart losers can eventually be thrown on "dummy's" magnificent club suit.

Win the opening lead with the diamond ace, and ruff a diamond with the spade ace.  Lead the spade five to North's eight, and ruff another diamond with the king.  Lead the spade ten to North's jack, and ruff the last diamond with south's last spade, the queen.  Now return to the North hand with the club queen, and lead the spade nine.  This draws the opponents' last trump, and as South has no spades left, he discards the heart six.  The South hand is now high and the grand slam is home!

Jack wrote
Maybe I'm missing something, but I find myself disappointed with the sequence specified in the bridge solution.  If you move two diamonds from West, say the 10,5, and replace them with two hearts from East, say the 10,2, then West should still lead the K of diamonds.  West will drop his club on the third diamond ruff, and South can't get to the dummy to clear trumps.  South needs to use the club entry before the trump entries...

This is one example from Dorthy Truscott's book "Winning Declarer Play."  Buy the book, read it, and rereat it a dozen times.  I guarantee it will improve your bridge game.
