Question:

Partner opens 1NT. What is your plan with: 

10854
8654
2
9732

Answer:

Pass. While you may strike gold if you use Stayman and partner has a major, you are in big trouble if partner bids 2. Some players use a method where after the 2 bid, 2 asks for partner to pass or correct to 2. Even if you've made that agreement, you need to hope partner remembers (and doesn't think it's invitational).
