against ecient in nding and avoiding slams a strong op ener and the resp onse N is forcing against the weak variant A strong op ening may b e a tactical weak ness at least when it is only mo derately strong Responses to as in Tangerine Opp onents are often eager to anyshape use psychics whichtendtomake the bidding hearts more random than usual In order to avoid this spades Tangerine has an ambiguous op ening showing N balanced either p oints and a balanced or semibalanced clubs hand or with any shap e If the opp onents diamonds try any psychics they risk fo oling themselves exactly
