Riding the MTA

South to make 7
Opening Lead: 9

This nifty layout utilizes a double transfer squeeze, which is quite rarely seen.

Declarer wins the A and finesses in diamonds.  Trumps are drawn, then the J is led, covered and won by south, transferring the heart guard to west.  Two spades are played off; on the second, west is squeezed in three suits.  He must unguard a minor — say, diamonds; dummy discards a club.

South now leads the 9, covered and won in dummy; this transfers the heart guard back to east.  Then, A, club to the king.  The lead of the last trump squeezes east in hearts and clubs.

If instead west unguards clubs, dummy throws a diamond.  Now the 9 nine as before, followed by the A-K.  The last trump squeezes east in hearts and diamonds.
