TPGK facing small c/r from strong player

[Fly]

Villain in this hand is 2p2er Olgi, he runs about 22/18/5 over 700 hands. His flop AF is 14.5 (wow!!). Before this session I hadn't played w/ him for a long time so I don't really remember any history (if there is any?). This session we played one hand where he he raised in the CO and I called otb w/ 87cc. Flop came K25hh. He made a small cbet and I called. Turn came 7o, he bet like 2/3 and I called. River was check/check and my sevens beat his 6 high . At this table I'm pretty sure I had been playing more aggro than normal but I'm not sure what I was running at.
