Opener's Rebid with a Medium Hand after a 1-level response

You've opened 1-of-a-suit but don't have a minimum (about 12-14), but neither do you have a maximum (about 18-20). You have to choose a rebid. With that in-between range, opener won't have a balanced hand (would have opened 1NT with 15-17 balanced). So, your possibilities are: 1) Jump rebid your suit (6+ card suit, roughly 15-18 in playing strength) 2) Jump raise your partner (4-card support, roughly 15-18 in playing strength) 3) Bid a new suit (very wide range). For 1♠-1♠-2♠ you could have a dead minimum, but could have up to about 17 or 18 (because 1♠-1♠-3♠ would be GF) .

Note: In #3,  "Bid a new suit" does not refer to a jump shift (GF) or a reverse (forcing one round).

    4♠

    Answer: 4

    3♠. No need to mention spades--you already have found your 8+ card fit. You are too strong for only 2♠, but not strong enough to do more than invite with 3♠.

    2♠. You don't have enough to jumpshift to 3♠ (game forcing).

    1♠. You must show your major, but you aren't strong enough to jumpshift to 2♠ (game-forcing).

    3♠

    Answer: 2

    2♠. You have only 15 HCP, but this hand is worth much more. With a void, a great 7-card suit and a fitting honor in partner's suit, you are worth this reverse. It is forcing 1 round (not to game). It shows 4 hearts and longer diamonds and a good hand. I can't think of a more accurate description. A jump rebid of 3♠ would show similar strength, but is less descriptive than 2♠ which also tells the story about the 4-card heart suit.

    I wouldn't open 1♠. You sometimes have to look ahead before opening. I don't love opening notrump with two doubletons, but you need to consider a rebid. I wouldn't open 1NT with a five-card major and a four-card minor, but with this shape you have a no-win rebid problem that you could have easily avoided by opening 1NT.
