We play 5 major. My partner opened with 1 club. I had 5 heart cards with king heart, 3 spades cards: King, Jack and 10, two diamond cards, one of them king, 3 club cards- 2,4,5 In total I had 10 points so I answered 1 heart He answered : 1 spade (I understood it means he had 4 spade cards). How should I answer him back?
