I slightly miskeyed this - W should have been dealer, so ignore S's first pass (vul is correct).
E/W playing natural methods, reasonably competent club players but not star level. This hand is from the Whitelaw Cup VuGraph, where one of the commentators was friendly enough to chat with me about the lead. I'll just repost the conversation:
Quote
Jinksy: why would you prefer a C to a H lead here? i would have thought the clearer count it gave, the better honour holding, plus the fact that it's a major all point to Hs?
roswolf: declarer is ready for a heart lead by bidding 3nt therefore a club is the better lead looking at the black suits
Jinksy: that seems like it's getting into regress - if dec is drawing attention to majors by not bidding them, but directing the lead away from them by showing he's ready for it, surely that directs him to bid it on a weak H holding on that knowledge and so on ad infinitum...
roswolf: too deep for me but bluff bridge (pysching) is rarely encountered in england these days. human nature is to be ready for the "obvious lead" therefore do something unexpected if reasonable
Jinksy: i just mean it seems like when you have a regress like that, your optimal strategy in that pos is probably something like 'bid 3N with stoppish holdings in both suits and hope the opps get the lead wrong'
I've seen this kind of reasoning in books before (they 'look ready' for lead A, so make lead B instead), but I've always had this problem with it.
(I'll post the other hands in the first reply since I'll lose them otherwise - obviously don't look at it before picking a lead if you want to treat this as a lead problem)
