You hold: KQ9832, Q86,Q73,Q, everyone is vulnerable, and RHO bids 3C, Your call?
Some local experts bid 3S. Bill Pettis said yes at matchpoiints (which this was) and no at imps. Alan Sontag said no at any form of the game, "too dangerous". If you pass, then LHO bids 4C and partner passes. Its your call again.
Both Pettis and Sontag agreed that is was an easy 4S bid. Pettis said the 4S call was much safer than the 3S call, because partner must have an opening hand and can't bid. Sontag agreed, "the 4C bid made it easier since you know partner must have values and couldn't bid directly".
Partner's hand was J75, A3, AK1096,J75, if LHO doesn't bid, Sontag suggests partner can balance with 3d, and you can bid 3S". Its not clear that you should even reach 4S if LHO doesn't bid 4C.
In the actual game bidding 4S and making 5 when N didn't shift to a heart after the A of clubs was a top. 4 of the eight pairs bid 4S, 2 others played in a spade partial, and 1 NS pair was minus 150
