You are 2nd seat, unfavorable.
What’s your call? The opponents stand to have at least eight combined hearts, so we stand to get a poor matchpoint result allowing them to play in that contract. We recommend a takeout double, despite the vulnerability. Notice that you passed in 2nd seat, so partner should not expect you to have more in high cards.
We would have opened the bidding with the South cards. After opening one club, South has an easy one spade rebid if partner responds in hearts.
