When you add any bid to your repertoire, you give up something. When you play negative doubles, you give up the ability to double some low-level bids by opponents for penalty.
Even a lot of experienced players aren’t aware of the fact that the reopening double is an integral part of the negative double system. What if you’re in third seat and the bidding goes 1 by your partner then 1 by your RHO? It’s now your bid and you hold the following cards:
Playing in 6, South won the opening spade lead, drew three rounds of trumps and discarded his diamond loser on the A. Unfortunately the clubs broke badly, and South had to lose two club tricks. Down one.
When South opens 1, North can describe his hand best by a Bergen mixed raise (artificial and forcing). Now East must be able to double that artificial club bid as lead-directional if he wants to prevent North-South from recording +170 or 620+ in hearts.
Check board 7 of the ACBL-Wide Seniors Pairs :
On Monday, March 2nd, the North Bay Duplicate Bridge Club participated in the ACBL-Wide Seniors Pairs Game.
At Board 1, you have an immediate important decision to make. Which choice would you make playing in 3NT?
A. Take a sure 430 or
B. Take an extra chance to make another overtrick and 460.
Ever wonder why certain players always seem to do better than others. They win or place on a consistent basis, while you languish in the middle or bottom tier. In fact you tend to be intimidated by their stature or knowledge or ability.
