Original problem:
 	Seeing all four hands, make seven Hearts against BEST defense.

                               S 5
                               H 85
                               D AK7
                               C AK85432

	   S KT7                                S 86432
           H 9                                  H Q762
           D QT83                               D J62
           C QJT97                              C 6

                               S AQJ9
                               H AKJT43
                               D 954
                               C --

   It is considerably more difficult than it first appears.  Remember that
the defense can see all four hands also.
/* ---------- */

I have a partial solution, but I am posting it anyway in hoping that 
someone can complete the solution.

Case 1:  If the opening lead is a Club,
	 take it with A of C, and discard a Diamond from hand.  
	 Play K of C.

    Case 1.1:  If East ruffs with low Heart, 
	       then cover it.  Lead Spades until West's K of S is forced
	       out, then ruff it in the board.  Finesse a trump, and claim.

    Case 1.2:  If East discards a spade,
	       ruff it! (very important to shorten the trumps in hand.)
	       Play Spades to force out K of S and ruff it in the board.
	       Finesse a trump, and clean West's trump on the way.
	       Play the rest of Spades.  A of D to the board.  Another
	       Club ruff; the best East can do here is to discard a Diamond.
	       K of D to enter the board.  The remaining cards look like the
	       following

			S --
			H --
			D 7
			C 85
	S --				S --	
	H --				H Q76
	D QT				D --
	C Q				C --
			S --
			H AKJ
			D --
			C --

	       Lead anything from the board toward hand, you have the rest
	       of the tricks.

    Case 1.3:  If East discards a Diamond,
	       discard a Spade from hand.
	       Finesse a trump.  A of D to the board.  Finesse another trump.
	       Now play three rounds of trumps ending in the following

			S 5
			H --
			D K7
			C 32
	S KT				S 8643
	H --				H --
	D QT				D J
	C Q				C --
			S AQJ
			H 3
			D 5
			C --

	       Lead the last trump, West is squeezed.
	       If West discards a Spade or a Club, you can claim then.
	       If West discards a diamond, cash K of D.  The situation
	       is as the following

			S 5
			H --
			D 7
			C 2
	S KT				S 864
	H --				H --
	D --				D --
	C Q				C --
			S AQJ
			H --
			D --
			C --

	       Lead the last Diamond, and West is squeezed again.

Case 2:  If the opening lead is 9 of H,
	 get a free finesse.  
	 A of D to the board.  A of C to discard a diamond from hand.
	 Now play K of C.  The situation is similar to the above.
	 If East ruffs low, play as Case 1.1.
	 If East discards a Spade, then shorten trumps and play
	 as Case 1.2.
	 If East discards a Diamond, then squeeze West as Case 1.3.

Case 3:  If the opening lead is a Spade or a Diamond,
	 it seems that the above line of playing does not work
	 due to lack of transportation.  Anybody has solutions for
	 these two cases?
