If it goes 1♠ X XX I'd bid 2♣, just because I play pass to be punitive in these instances. However, I think my partner should bid just 2♥, which shouldn't go wrong with a spade void (it's not gonna be 1♠ 2♥ pass pass pass, unless partner has the hand you had or one more spade and then it won't be so bad to play just 2♥)
