Trump Coup

Playing technique.  The lead of a plain suit card from a hand without any trumps, through a player with only trumps left, thus forcing a ruff, which can then be overruffed in the next hand.  It achieves the same effect as a finesse  in the trump suit but without requiring there to be a trump to lead.  In preparing the play, the hand need to reduce the number of trumps to that of  the opponent has. Also, entries are critical in planning this play.

The lead was the king of diamonds on which East played the jack. South won with the ace and led a heart: 4 - queen - king. To eliminate any diamond ruffs, East returned the 5 of hearts. South played the ace and North followed with the ten. North's diamond bid with so few points suggested considerable length, confirmed by the play in diamonds, which indicated a shortage with East. South therefore took it that trumps were likely to have been 4-2 originally, and that the ten of hearts was a true card from an original doubleton. In that case South had to trap East's hearts with a trump coup.

After ace of clubs, then the queen, overtaking with dummy's king, South ruffed a club to shorten his trumps to the same length as South's.

Then led a spade to dummy and led a top club. If East ruffed, South would overruff, draw the last trump and return to dummy's winners with a spade.

In fact, East discarded a spade, but South simply continued with the clubs. After trick 11, East had 8-6 in hearts and South had J-7. With the lead in dummy, South was bounded to make the last two tricks.
