Bid 2 .  Generally with a good, distributional hand you should choose to bid your second suit rather than rebid your first suit.  You could certainly bid 3 (showing 15+ to 18- HCPs and 6+ spades), but then you have tossed out the opportunity to play hearts or diamonds.  2 shows 4+ diamonds and 12-17 HCPs.


Let’s look at what might happen over 2.  If partner bids 3, you have a fabulous hand that might even make slam in diamonds.  If partner bids 2, you can raise to 3 showing a heart fit and 16 to 18 HCPs.  If partner preferences back to 2, you can raise to three spades showing 16-18 HCPs and six spades and four diamonds….much more descriptive than jumping to 3 initially.


Yes, Responder can pass 2, but if they do so, they probably have a singleton spade so you are probably better off in diamonds than spades anyway.


Shape is what can push a hand to games or slams, even when the HCPs are not there.  Try to always bid out your shape (your pattern).
