How to Identify Extra Winners in Bridge
When you play a bridge hand at a trump contract, you count losers and extra winners. An extra winner is a winning trick in the dummy (North), upon which you can discard a loser from your own hand (South).
You can get rid of some of your losers by using extra winners. Extra winners come into play only after you (South) are void in the suit being played. Therefore, extra winners can exist only in a suit that’s unevenly divided between the two hands (and the greater length must be in the dummy). The stronger the extra winner suit (that is, the more high cards it has), the better.
Yes, you can have extra winners in your own hand, on which you can discard a loser (or losers) from the dummy. But actually gaining an extra trick from this process is rare.
This image shows you two extra winners in their natural habitat.
These cards fill the bill for extra winners because spades is an unevenly divided suit, and the greater length is in the dummy. After you lead the ♠3 and play the ♠Q from the dummy, you’re void in spades. Now you can discard two losers from your hand when you lead the ♠A and the ♠K from the dummy. Therefore, you can count two extra winners in spades.
By contrast, the cards in this image look hopeful, but unfortunately, they can’t offer you any extra winners.
These cards don’t fit the mold for extra winners because you have the same number of spades in each hand. No matter how strong a suit is, if you have the same number of cards in each hand, you can’t squeeze any extra winners out of the suit. You just have to follow suit each time. True, the ♠AKQ aren’t chopped liver; although this hand has no spade losers, it gives you no extra winners, either. Sorry!
The cards in this image contain no extra winners, either.
The dummy’s ♠AK take care of your two losing spades, but you have nothing extra over there — no ♠Q, for example — upon which you can discard one of your losers. This spade suit has no losers and no extra winners. You need to have extra winners to be able to throw a loser away. Your ♠A and ♠K do an excellent job of covering your two spade losers, but no more. You can’t squeeze blood out of a turnip.
