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 1
vs. any other 1-level bid.
Over any other one-level opening:
||= the two lowest-ranking suits
||= the two highest-ranking suits
||= 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 3
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.
