I'm with ggwhiz on this one. I like reversing with this hand, then jumping, if possible, in partner's suit. It should show a hand with ♣ shortness that is just too good to splinter.

Give responder something like ♠ KQxxx ♥ Qxx ♦ Qx ♣ xx and it's hard to move over a direct 4 S (or 4 H if you flip the majors). Neither will this hand move over a splinter which can be made on a decent 16-17. But after something like

1 ♦ - 1 ♠
2 ♥ - 2 ♠
4 ♠

responder will know opener's hand is either 4=3=5=1. 4=4=4=1, or 4=4=5=0 and very strong and might make a move.

How does responder know opener has 4 spades rather than 3? (3451 or 3460) That would make a difference in many cases where responder considers slam, as a 9-fit plays a lot better than an 8-fit.

IMHO, always support immediately with support. If not playing a system where I can show a strong 4441, I'd start with 1D and rebid 4C.

3 cards in spades passes 3nt, period.

I would splinter, We play that a jump to 4♥/4♠ specifically denies shortage.

I am not a fan of the 1♦ opening. I would open (in order of preference):
- 2♦ - if our muti includes strong 4441 hands.
- 2NT - I am prepared to treat as balanced. (Much less of a distortion than, for example, reversing with this shape).
- 1♥ - We play four-card majors and whilst I would normally open 1♦ with this shape, we are so strong that we can open 1♥ and cope with any response (if we get any).
- 1♦ - 4th choice!

Assuming you don't open 2NT and you bid 1D and partner responds either 1H or 1S what is your rebid?

Thanks all

I used to play an opening of 2 diamonds to mean a 4-4-4-1 and 17-21 HCP. Responder bids 2 Hearts to ask for the singleton. Opener bids the suit below the stiff. Then responder calls the shots. If it is 1 diamond--1M, then I ask for aces. This hand is too good to settle for less than slam if one ace is present in partner's hand.

4S.

This shows about 20 points, typically balanced or semi-balanced with 4 card support.

The power raise is superior to the 4C splinter rebid. With a stiff King, you don't want to encourage partner to devalue club holdings like Axx, AQx, Qxx, or QJx by showing shortness in that suit.

3 ♠ in this auction would show the 3=4=5=1 or 3=4=6=0 hands.
