In bridge, Ghestem is a conventional two-suited overcall that shows at least 5-5 distribution. The convention is named for its inventor, the late Piere Ghestem of France. The overcalls differ if the opponents opened 1C vs. any other 1-level bid.

Over 1C:

2D = H and S
2NT = D and H
3C = D and S

Over any other one-level opening:

2NT = the two lowest-ranking suits
3C = the two highest-ranking suits
Cuebid = the top and bottom suits


Point strength needed for Ghestem depends on partnership agreement. Here are three possible approaches:

  • Constructive, showing 12+ points
  • Any strength, 0+ points
  • Weak (0-10 points) or strong (16+ points). With an intermediate hand of 11-15 points, begin with a simple overcall and bid your second suit later.


Ghestem vs. Michaels

Compared to the Michaels cuebid, Ghestem always specifies exactly two suits. A Michaels major-suit cuebid, on the other hand, shows the other major and an unspecified minor.

But Ghestem has its own drawbacks. The 3C jump overcall loses its weak preemptive meaning and also forces the bidding up to the 3-level. Compare this to Michaels, in which a 2-level minor-suit cuebid lets the overcaller compete at the 2-level.
