1st Hand: You have 11 running tricks spade finesse or finding the right Hearts card will give the 12 trick however, another way is to play a strip squeeze on LHO over the Heart Ace and Spade queen for the 12 trick.The club lead influence the strip squeeze line as passive leads are normally made when holding much values you dont want to lead from or holding nothing ( that's based on aggressive leads is preferred against slams). I would probably cash the Spade Ace, 5 clubs and 4 diamonds from opponents discards you might be able to find the spade queen either by finesse or strip squeeze. If you take this line your last 3 cards will be K♥ and KJ♠ depending on clubs and diamond distribution and opponents discards you might find the right decision 1- end play LHO 2- Finesse Spade 3- cash spade king to drop the queen (note that some players might discard spades to hold the stiff queen as a counter move to the strip squeeze). Also, note that this line will reveal RHO if he hold all the missing key cards as he will be automatically squeezed and it will be much easier to make if that's the case. This line still loses on some layouts I don't think there is 100% play here. 2nd Hand: After bidding twice vul against non I don't think your p has Qxxx in Spades or he might have raised to 3♠ also, all kinds of switches doesn't seem promising so I'll return high spade hoping P is able to ruff over dummy.
