The Whitfeld Eight

by William Whitfeld

Spades are trump.   South to lead and win all.

South trumps a club, then leads a spade.  East must keep all his clubs to prevent establishment of declarer's long card; so he discards a red suit — say, hearts.  South also sheds a heart, then plays a heart to the ace.  The ♣A is cashed, discarding a diamond from dummy, and a club is ruffed.  Now the lead of dummy's last spade effects a double squeeze; east must guard clubs and west must guard hearts, so neither opponent can guard diamonds.

Trap: cashing the ♣A early would compel a premature commitment from dummy.  East would hold onto the same red suit as the dummy, and the squeeze would evaporate.
