Surely the worst think that can happen is that partner passes and we have a better game? KJxxx xxxx x QJx, for example. I suppose. I don't see how the alternatives get us to 4♠ either. At least if pard has 2=3 in the minors I expect a preference to 2♦ and we will get to 4♠. The 3♦ bidders will play 3♦ Lets say you bid 2C. Pd gives preference to 2D. Then what? 2S can be bid on a 3 1 5 4 that is not as good by far as the posted hand or a 3163. Are you going to bid 3S? That may well get you overboard when 3D was your best spot. It seems to me the 2C bidders are only delaying a possible problem. Yeah, I'm planning on rebidding 3♠. That gives partner a reasonable chance to evaluate his hand and make a decision. He'll be expecting 3154 rather than 3163, but I can live with that. We won't end in a terrible 4-3 spade contract, can reach game wen that's reasonable and else play our best (or 2nd best) partscore. We might end up in 4♦ when 3♦ is the best spot, but then I just have to take 10 tricks, wtp? :rolleyes:
