I'm lag and am in a bad spot, $50NL 6m

The hand before this I was caught making a raise in early position with A8s and being agressive with no hand on the flop or turn then catching an ace on the river splitting the pot with AQ (K933A board), i've been raising alot preflop, with many marginal hands but the previous hand was the first ive shown down in awhile, won many hands betting the pot on the flop, the table is full of alot of tight and agressive players.

The river bet looks like a post oak bluff, or begging for a call from me if I have an ace as I represent. I have the feeling I was outplayed here but at the same time I am feeling very second best here.
