People like Marty Bergen have written things like, "almost anytime you're responding to your partner's 1NT and you have few clubs, you should respond 2 clubs," Stayman (this is a paraphrase, not an exact quote).
The point I think he was trying to make was that you should aim for a two-level suit contract, even with something like (s) xxxx (h) xxx (d) xxxxx (c) x.
Here, you're bidding Stayman while, weak, not aiming for a game contract.
If partner responds 2 diamonds (no four card major), should you just pass and be glad he bid your "suit," even though he might have a 3-3-2-5 distribution? If he bids 2 hearts, should you accept what may be "Moysian" (4-3) fit and pass?
In general, should you pass whatever your partner bids, after bidding a weak Stayman? Are there exceptions to the rule? Or would you recommend against bidding this way with the hand listed above?
