Kokish Game Tries

• Bridge Conventions (List)

The auction 1D-2C is a problem auction for Standard bidders. To solve this, 2/1 and strong notrumpers have often chosen to play it as game forcing. Kearse/Shienwold system bidders have different problems; 1D/2C can sometimes be bid on weaker hands than Standard bidders. Then if opener has an unbalanced hand, disambiguating the responding hand's values can be difficult.

The Standard approach is to allow the rebid to be pretty much anything, but that (in particular in K/S) forces a rebid by responder and leaves the auction unclear. (Playing Standard, who is responsible for starting the search for a 4-4 major suit fit?)

A set of rebids, attributed to Eric Kokish, attempts to handle these problems. They were designed for use along with a weak NT, but work with any NT range. I'll assume 15-17 NTs and others can transpose from there.

1D-2C

 	2D=5+ diamonds and 1 round forcing 	2H = 4441 hand 	2S=good club raise  	2NT= balanced hand with 12-14 HCP 	3C=bad club raise 	3D=16+ HCP, good 6 card diamond suit 	3H,3S = splinter in support of clubs 	3NT= 18-19 balanced 

Responder's major suit rebid is normally a 4-card suit, but can sometimes be just a stopper; opener is not expected to go past 3NT. Opener's 2S and 3C deny a four-card major, but 2D often contains one.

A bidding convention is an agreement between two players on a different meaning of a bid in the card game bridge. These agreements are made so that partners can more quickly determine which contract, with both their cards, they can win together. Often, conventions are forged together into one, which is then called a bidding system.
