I don't think you need anything more than just an overcards to bet the turn HU in this pot. But you do need to have a pretty good feel for the opponent, and access if you think his turn bet means strength. There's a good chance you're still ahead on the turn.

Against an unknown Party 1/2 player I bet this turn a lot. Almost always, since the pot is heads up. 100 hands later, after I have confirmed my read that he is a typical weak tight Party 1/2 player, I'll usually bet the river unimproved too and watch him fold.

Reads are extremely important here, as is your table image. Some players will never fold their bottom/middle pair, especially if you've made some plays that look strange to them -- they'll always call you down. I'd still bet the turn then (likely) and but would check the river.
