"Pass" is what an expert (Frank Stewart) advocates with the following hand, at rubber, at favorable vulnerability, in response to a one diamond opening bid by RHO.
Specifically, Stewart wrote, "I would be ashamed to table a hand like that, after forcing my partner to bid." I (the OP) am a conservative bidder (perhaps overly so), but "Pass" seems overcautious even to me. Especially when non vulnerable vs. vulnerable.
The worst case for partner is a "Yarborough" and a 3-3-4-3 distribution (with the four in opponents" diamonds). But as a practical matter, the worst likely scenario is that partner will have only Jxxx in his "best" suit. This would play relatively well opposite KQxx, KQx, or QTx in the three unbid suits. A three pointer, with all three non-diamond jacks, could play very well. I don't see the shame in that, even for a forced bid.
I would rather double with the above hand than Stewart's other offerings, hand one, which had three cards but no honors (or even a T, 9, or 8) in the spade suit, or hand two, which had a "side" suit with only two cards (clubs).
Is a hand that meets the description in the title a clear double? Or are there 14 hcp balanced hands (regarding both cards and honors) that should be passed?
