With the addition and evolution of various treatments and conventions, it is now more generally ...
Gerber convention. Gerber is a contract bridge convention devised by William Konigsberger and Win Nye from Switzerland [1] who published it in 1936; John Gerber of Texas introduced it to North America in 1938 where it was named after him.

After an overcall by RHO, assuming that the bidding has not gone past 1NT, the convention is still on (for example after 1 ♦ - (pass) - 1 ♥ - (1 ♠) - X where X is a Support Double). The XYZ sequence that starts with 2C after 1-1-1 usually begins an invitational sequence. For example, 1D - 1H -1S - 2C -2D - 2S shows an invitational hand ...

Key to this process is that players evaluate and re-evaluate the trick-taking potential of their hands as the auction proceeds and additional information about partner's hand and ...

As such, it makes overcalls more difficult, since they have to be made at the ...
2/1 game forcing (Two-over-one game forcing) is a bidding system in modern contract bridge structured around the following responses to a one-level opening bid: a non-jump response in a new suit at the one-level is constructive and forcing for one round, a non-jump response in a new suit at the two-level is forcing to game, and.
