1 ♣ Pass
1 ♠ 2 ♥ ???

My bid was 4 ♥, intended as stronger than 3 ♥. Not a good bid since 3 ♥ is already unlimited and the 4 ♥ bid suggests a void.  

I like 4 ♠.   If you bid 4 ♠ you are saying that you want to play 4 ♠ even opposite only 6 HCP with 4 spades.   After you 4 ♠ bid West can calculate support points and see if slam is in reach.  

West had ♠A87652 ♥3 ♦65 ♣Q1064, only 6HCP but around 14 support points.   With East promising around 19, slam should be a possibility.
