I'd play my partner for 5card support and opener for K 3rd in ♦, so I see no point in blowing a trump trick on a ruff I cannot prevent. Hard to picture a 2NT call without the remaining 3 Ks and one or likely both queens. However partner may still have ♣Qx(x) or ♣xx and ♠Qx, in which case there will be 3 late club and trump losers. I take A♦ and continue passive J♥.

I do not quite understand the 3♠ bid. If partner has a ♠ stop (very unlikely) they are likely to go off 3-5 in 2S and yet there may not be a game for us. Even if he has no stop - 2♠X could be best. You rather need some agreements on pass and dbl after opps bid and raise here. I think everything has been said about a Moysian with no ♠-shortage in the short trump hand.

I expect partner to be full value for 3S and 4 cards since you only show 4 yourself. XX probably bluff/semi-bluff with long D. partner surely would have bid 1S weak 4cards and 2/3S with weak 5cards. holding values in a situation where partner and opps told him he hasn't any he decided to pass to see what is being offered and act accordingly. I bid 4S
