We encountered this hand yesterday in a f2f game. Let me explain the beginning part of the auction. I opened the bidding 1C. My partner then bid 1S. Our system is that if the opener does not have shortness and has 12-14 hcp, (defined as a singleton or void) then we bid 1N, even with a semi balanced hand. Not sure if this hand is too unbalanced for that treatment, but the alternative would be 2C which is not any better. This way partner knows that you have at least 2 of their suit.
My partner then bid 2D, which is xyz and an artificial game force. I obviously still know nothing about diamonds at this point. I bid 3C indicating real clubs and likely 5 decent clubs. My partner then bid 3D, which I took as natural.
Knowing that the lead would be coming to me, and still not knowing about support in clubs, but now knowing that diamonds were covered, I bid 3N.
Now the questions we had -- Partner bid 4C, which I took to be some support in clubs, a run from NT due to a distributional type hand (he in fact did have 1 singleton) - and I felt that we were strong enough so I bid 5C. My partner having such a strong hand, and likely influenced by his singleton AH, bid 6 clubs.
We got a mediocre result because 7N makes, as does 7C. In fact, we made 7C.
My partner was "hoping" that I would respond to his 4C bid using Q-Gerber. I told him I thought that was not on even though the last bid was NT because I had bid clubs 2 times during the auction. Even if it were, I would have responded 4D indicating little interest in slam. At that point, he would have bid 4H saying tell me anyway, and my response then would have been 4S (we play 1430 Q gerber). Not sure that this would have changed the bid to NT vs clubs anyway - again given his singleton heart.
Given the bidding sequence to get to the 3N bid, is there any way for partner to ask about key cards, or given that partner has all but one anyway, is it better to just go to 6 and hope that is good enough.
Curious as to how the bidding should have gone so that we at least get to 6N instead of clubs, and of course it would be great to get to 7C or 7N.
Thanks in advance.
