PS 50/50: When Only 1 Hand Beats You

My way isn't definitely the right way. I don't love 4-bet pushing PF. I'd much rather call and crai on a friendly board (which was the plan). Normally, I definitely would bet the turn, but for some reason I decided to check it to disguise my hand. I thought it was rare for someone to check behind twice here, even with overs. On the river, as played, I REALLY don't like checking because I think we get AK to call and he very rarely has KK/AA here.
