  Your partner denies having Spades, and cannot bid the minor suits because he has fewer than the 9 or 10 points needed. But he does have at least 6 HCP. You must not leave it in NT, with a maximum of 4 Spades between you. Bidding two diamonds will allow your partner to choose between the red suits at the two level, knowing that you have a 5-4 distribution.

  You know partner might only have 6 points, and 9 at the most, so game is not on, since we are shy of 25. We've got good Hearts, but we don't have suit agreement in Hearts. We've got Spades covered, so the chances are high that our partner's limited strength is in the minors. So there are probably enough stoppers to be safe in 1NT. Probably better than 2H, where he could be short or even very short.

  With only 15 HCP, you are one short of what's needed to invite to NT game. Also, NT may be bit dangerous with a weak doubleton in diamonds, when your partner could have as few as 6 HCP spread across the 3 weakest suits and therefore little protection in diamonds. Your partner is probably denying having 3 Spades, since he is allowed to give weak support in Spades with 3 cards if he has no good alternative. Not an easy decision: either pass or 2 Spades.
  Now have a look at partner's hand - he's East in the dela shown. Was he a bit naughty not bidding those Spades? That would have made your life a bit easier.

  You know your partner has 6-9 points. So a NT game is unlikely to be possible since your maximum combined point count is 24. What's the best part-score you can find? Spades are no good: if partner had 4 Spades, he would have bid them. So, either rebid Hearts, or leaves it at 1 NT.
  
  But there's little point rebidding Hearts, since he will only have 0-3 of them, and even having 3 is unlikely, since being a Major he would probably have bid them with only 3 - if he'd little shape such as an outside singleton.
  
  If in doubt, only rebid a suit after a 1NT bid from partner if you have 6 or more of them.
