My short answer: check the turn more.

Then usually fold the river, and sometimes call the river. (I'm talking about AK on a dry board). Sounds like these blinds are on to you. I don't think they are continuing beyond the flop without a pair, so take the free card on the turn because you are behind, and fold the river if they bet.

This is an adjustment I have been making based on the opponents. Against two loose passives who call my A high flop continuation bet, I will try to assess how much of the time they have a pair when they do that. With those who are close to 100% I start checking the turn and folding UI on the river. They may still check the river with their little pairs so you get more info.

Then of course you have to occasionally call on the river because even bad players will try to take advantage.

There are some loose passives who will fold on the turn with nothing. Against them you have to bet the turn with your A high and check behind on the river UI.
