You arrived in a reasonable 6♠ given the auction where East is a favourite to hold ♥A. Without interference the slam is rather bad, around 34% because it needs ♥A on side and clubs 3-2.
Anyway, that's academic, because East overcalled 3♥ after 1♠ pass 2♠. West leads ♣9. Plain sailing now, isn't it?
