A commenter identified that the unique model of this query was not as fascinating as some aspect points accompanying it. So I’m going to ask a second query to handle these “aspect points.”

At matchpoint duplicate bridge, not susceptible vrrsus susceptible, and sitting West, I held

♠ AK32
♡ J643
♢ 6
♣ JT82

Partner (East) opened one coronary heart, South overcalled one spade with the next, a hand that I thought-about “mild” for the aim.

♠ Q874
♡ 973
♢ AK85
♣ 53

I raised to 2 hearts, North bid two spades, and there have been three passes.

South’s “mild” overcall acquired them a high rating on the board, and us a backside. Was it a correct overcall, that’s, was South “skillful” or “fortunate.” More to the purpose, ought to companion or I’ve bid three hearts in some unspecified time in the future?
