Having a 5-crd minor doesnt mean responder has to show the suit: ♠ K32 ♥ QJ2 ♦ AQ ♣ J5432 favors a NT response, since the club suit is bad, and all suits are stopped. We bid a forcing 2N. With ♠ QJ32 ♥ KJ ♦ Q5432 ♣ KJ we bid 1♠. Chances for game appear to be in spades or NT. For 5D - partner with the weak variant doesnt have 4 diamonds we need too much extra.
Continuations over 2♣, 2♦ responses
Opener shows a 4-crd major (hearts, if both). With a strong club opener doesnt jump, since the auction is game-forcing. Raising responders suit promises a 4-crd fit and no 4-crd major it doesnt have to have extras. Responder rebidding his suit is forcing...
OK, great. Some questions remain.
1. If opener has 5+ clubs and a 4 card major, does he bid 1♣-2♦-3♣? Does it matter how strong he is? (And presumably 1♣-2♣-2♦ shows a strong hand with diamonds? That would make this pretty much the only sequence where it's good to have this hand type...)
1a. If the answer to question 1 is to bid the clubs, how does opener then make a forcing raise of the major after 1♣-2♦-3♣-3M?
2. Say it goes 1♣-2♦-2♠. Should responder, with 4 hearts and no club stopper, bid 3♥, or is it better to rebid his minor even if it is only 5 cards?
2a. If the answer to question 2 is to rebid the hearts, how does opener (say he has a strong hand with 5♠4♥) then show a forcing heart raise? 1♣-2♦-2♠-3♥-4NT is surely needed as a quantitative slam invite, isn't it?
