Most likely butchered AQ TP+NFD, 6-max

Why does he need to be deep to check behind here?

[soah]

Because he can't get blown off his draw when he is short.

consider the two cases where you and villain each have 1 psb left on the turn versus the case where you and villain have 2 psb or greater. in the first case, you bet hand over and just hope that in the long run your pot and fold equity on the turn make it a +ev move. in the latter case you have to deal with the % of the time where villain can checkraise. a great % of the time, a turn checkraise means that our equity is ~20%. we don't want to bet the turn and be forced to make a fold when we could have seen the river for free. you miss out on the chance to get value from his range of weaker hands as you are able to when you both only have 1 psb.

Ah. Makes sense.
