Bergen raises.
There are 4 types of Bergen Raises :
  • 1- 3 A "Constructive" raise, showing 7-10 points and exactly 4-card trump support. 
  • 2-3 A "Limit" raise, showing 10-12 points and exactly 4-card trump support. 
  • 3- 3 in the agreed major A "Preemptive" raise, showing 0-6 points and exactly 4-card trump support. 
  • 4- 3 in the unbid major An "ambiguous splinter" raise. An unbalanced, game-forcing raise promising 12+ points and 4-card trump support, with an undisclosed singleton or void. With a balanced game-forcing raise, use the Jacoby 2NT convention instead.
