Should I Run this Honour? When wondering whether to take a finesse by running an honour, check how many cards you have backing up your lower honours. The longer the sequence, the stronger the sequence: look for tens and nines in particular.
When your partner opens 1NT, you know almost exactly what kind of hand he holds. It is one of only 3 possible shapes: 4333, 4432 or 5332 - the balanced hands. And it sits in a very narrow point range: 12-14 if you are playing Acol; or 15-17 if you are playing Standard American.
North opens the bidding 1♦ and East overcalls 1♠. Sitting South, we have a lovely 6-card heart suit but only 6 high card points. We want to do something but aren't strong enough to bid hearts. Luckily, we have the negative double which will ask partner to bid one of the unbid suits. North now bids 2♣ and when it comes back to us, we must decide what to do.
