inducing bluff vs missed draw

[booger]

PokerStars No-Limit Hold'em, $0.25 BB (6 handed) converter
I had doubled through on a $50 table and tripled up on a $25 table when this came up on a $25 table. I only had been 3 tabling for about 20 minutes and was up ~$100-fast early rush like I havent had in a long long time and for some reason didn't play this normally and kept thinking or hoping this river check would induce a bluff. This player is definitely LAG. I win the pot any guesses on villian hand? I normally bet close to pot on all streets but this guy was getting beat up a bit and I felt he would take a stab after the check....he left the table after this hand
