A simple overcall has many roles. It can suggest a sacrifice, buy
the contract, or ask for a lead. The following hand has a lead
directing overcall and also shows how important carding is to the

BIDDING: After South's 2 opening bid, North used an
artificial 2 bid to show a very weak hand
containing 0-3 high card points. East took advantage of the
vulnerability to make a lead directing overcall and North-South
continued on to game.
PLAY: West led the club three to his partner's jack. When
East continued with another high club, West had the opportunity to make
a SUIT PREFERENCE play. He followed with the ten to show values
in hearts, the higher ranking of the two side suits. Switch his
red suit holdings and he would have played the five of clubs.
Looking at the problem from the East seat, without help from his
partner East would have no idea how to continue after winning the
second club trick.
Note that without the heart shift, declarer will make the hand by
drawing trumps and then discarding two of dummy's heart losers on good
diamonds. The opportunities for suit preference occur frequently
so remember: every card you play has a meaning.
