When partner preempts the bidding at the 2-Level, and we have a good hand we expect the auction to be difficult. We need to have good agreements with partner and exercise some good judgment to get to the right final contract. When we have a fit for partner’s suit (especially a Major suit) then we know what strain we are likely to play in. We need to exchange useful information with partner. There are a variety of systems for accomplishing this, including Optional Feature, Ogust, Steps, and Modified Ogust.
