Good Fold?

[Two_Slick]

Table is very loose and fairly aggressive. I've seen villain play just about any hand regardless of number of bets to him. I hate folding on the river to a LAG capable of a bluff, but the bet seemed very out of place (and it seemed like a terrible place to bluff since I haven't folded to agression regularly).

We were HU for 1 hand at the end of the session and he made a similar bet:

He could have made a move the 2nd time thinking I would fold to any A on the river. Thoughts?
