Create an end position that follows the following restrictions: -All high cards, jack through ace, in each suit are used. -N/S can win all of the tricks except one in no-trump. -N/S can not win all of the tricks except one in any suit. In addition, minimize the N/S HCP. Here's an example: [hv=pc=n&s=shqdak4ca54&w=skjthkjdc62&n=saq3hat2dc3&e=s4hdqj3ckqj]399|300[/hv] N/S has 5 top tricks. In no trumps, cash ♦A and ♣A, discarding a heart. Now lead the ♦K pitching a spade. If west pitches a spade, play a heart to the ace and concede a heart. If west throws a heart, you have an extra heart winner. If the end position is in any suit except diamonds, you have 2 unavoidable losers, and in diamonds, if you try the same squeeze east ruffs when you play a heart, or if you play ♦AKx, east returns a spade! and you have to lose a heart at the end.
