KJxxxx and an outside K is certainly too good to pass 1NT at teams, I'd have thought. I don't know why, I just seem to have a bit of a blind-spot over this issue. I'm posting this because I felt I hadn't properly dealt with a pupil's question on this issue, so maybe I should have posted this in the B&I forum instead. I guess QJT9xx you'd certainly transfer...With AKxxxx you are unlikely to be passing 1NT, but with AQxxxx or KQxxxx there's a fair chance your suit will run, there's also a fair chance you could be totally stranded from it in 1NT.
