So you think he'll check back Ax, but he'll bet KJ, QJ?

The problem I see with this is that it's an utterly confusing line, and I don't think you'll get lots of calls by KQ, KJ, JQ... on the turn with that bet sizing.
That and the range you're getting value from by donking the turn, you would get more value from by just c-betting the flop and turn imo.
