Bidding : (W)   1NT - 2♣ (- 2♥ - 4♥)
 
Many Novice players will respond with 3♠, after all you have 5 spades.   The smarter bid however is to bid Stayman  2♣ first !  This way you can check on Opener's 4-card heart suit if he has one. 
  If Opener replies in the negative (2♦) you bid 3♠ at your next turn ! (This shows that you have 5 spades and 4 hearts.)
