This hand came up in a club game (IMPs) the other night.
You open a 10-12 NT. West overcalls 2♠, spades and a minor (at least 5-4), partner doubles to show invitational values or better. 3♥ from you, 3♠ by partner, asking for a spade stopper. The auction ends after you bid 3NT.
West leads ♣K which you allow to hold, East following with the 3, giving count when a king is led against NT (low-high from an even number). ♣J continuation by West.
You are far away from taking 9 tricks. Plan the play please.
