Yes, 3♣ - just not enough firepower for 3♦. If pard take delayed preference to diamonds, I will press on.
Anyone think 3♦ is forcing (by pard over 3♣)? I think you can make a very strong case that it is.
In earlier discussions, I came to the conclusion that after 1
♣ 1
♠ 2
♦ then responder, if holding diamonds and enough values for a direct 3
♦, should show that now even if he holds five spades. My thinking was that firstly opener usually does not have three spades and secondly it gets tough to show both the strength and the shape if, after the 2
♠ rebid, opener cannot raise spades. So far, on a small sample size, this seems to work. If opener has three spades he bids them at his third turn. Now if you played the way you suggest, that argument would be weakened significantly. Perhaps it should be forcing.
Forcing wouldn't really help here, since I doubt responder with modest values would want to make a forcing 3
♦ bid when he has no reason to believe I have five diamonds. Possibly it is better here for it to be non-forcing. With QJx he could, perhaps, decide to give 3
♦ a try figuring that it gives me another opportunity and if I pass, well QJx may suffice.
Btw, I don't see the 3
♣ bid as promising six cards. Give me 1=3=4=5 with values concentrated in the minors. What am I to do over 2
♠? Taking a potshot at 2NT on Qxx doesn't appeal to me, and even if I have Axx it seems I had better have at least the clubs ready to run.
People say "It promises six clubs but sometimes you have to lie". To me, this means that it doesn't promise six.
We got this far.
2♠ showed five spades, was forcing, did not promise or deny the strength to go on. If N had four diamonds and five spades he would have shown the diamond fit rather than rebid the spades, but other than that the 2♠ just shows five spades.
3♦ over 2♠ would now show the 6-5 shape and be forcing, 3♣ would not be forcing, nor would it promise any extra shape, other than a preference for 3♣ rather than 2NT, since opener had to bid something over 2♠. Your call?
This was a matchpoint game.
