Gerber Ace-Asking 4C -------------------- 4C is used as an ask for Aces. The response are: 4D 0 or 4 aces 4H 1 ace 4S 2 aces 4NT 3 aces The king ask is 5C and the responses are: 5D 0 or 4 kings 5H 1 king 5S 2 kings 5NT 3 kings Playing Gerber, 4NT is natural and quantitative. In most cases people play Gerber only after a NT opening or a natural NT bid. However, Gerber may be played after any opening or response-- if the partnership agrees on it. In some cases where 4C may be confused with a natural club bid, a jump to 5C can be use to ask for Aces (this is called Super Gerber). Other people have solved this problem by playing that if clubs could be a suit, then 4D would be the ask (I think this is called Redwood, but I'm not sure). About the 5C King-ask --------------------- In some cases you may want to *play* in 5C rather than signing off with 4NT. This problem of 5C possibly being natural and possibly be a king ask is solved by this partnership agreement: 5C is natural and to play 5NT is the king ask While this uses up a whole level, you generally do not lose anything since the partnership has all the aces and the king ask SHOULD be used for finding a GRAND SLAM, not a SMALL SLAM. In a 1991 or 1992 Bridge World Magazine, one author had an interesting suggestion for new responses to the 5C ask: instead of responding with the number of kings, respond with the number of quick tricks that you have: 5D shows 0 quick tricks 5H shows 1 quick trick (a king) 5S shows 2 5NT shows 3 6C shows 4 6D shows 6 etc... Quick tricks are counted by: counting the number of tricks that the suit will run. Thus, KQx is 2 tricks since you expect partner to have at least Ax. K is 1 trick. KQ is also 1 trick (for it to be two partner needs Axx). AKQJTx is counted as 5 tricks-- you don't count the Ace since your response to 4C already showed that one. Thus, after 5C (which confirms all the Aces), holding: S: KQx/ H: Kx/ D: QJxxx/ C: Axx you would respond 5NT to show 3 quick tricks (the K of hearts and the KQ of spades). You assume that partner has the Ax of the suit and respond accordingly. S: Qx/ H: KQx/ D: KQJTx/ C: Axx You respond 6D.
