You think that when someone makes a vulnerable jump overcall in hearts, they are more likely to have the ♦K than the ♥A?
If he really holds A, why the lead was club? What types of hand and quality of H should overcall 1H in vul? And what types of hand and quality of H should overcall 2H in vul and claim as weak?
If he holds A, the lead was club, be careful that the lead was signleton but it seems not likely to happen (16 cards in spade and diamond, 10 out of 26 in opps. hand has filled in diamond and spade). If one holds singelton club, means south is somehow 2 suiters hand, may be 1-6-0-6 or 0-6-1-6 or 1-5-1-6 or 2-5-0-6, which is unlikely to happen because north will be 2 suiters in spade and diamond also.
My sense told me that after such competing bids but they don't lead their suit, usually the players leading is holding that suit A.
