Unsurprisingly, overcalling works out poorly: [hv=d=w&v=n&n=sxxhktdtxxxcakqxx&w=sakhxxxdajxctxxxx&e=sqtxxxxxhxxxdqxxc&s=sjxhaqjxxdk9xcjxx]399|300|Scoring: IMP[/hv] EW can take 4♥ down four on good defense. They have to double to win more than 1 IMP, however, as South will likely lead diamonds against a spade contract. It's interesting to note that if West opens a Precision 1♦, 4♥x will be a very likely contract for N-S.
