odds to chase?

[RustedCorpse]

I really felt like I was chasing during this hand. Table is incredibly passive with most hands. I've had checked down Ace high for winners at least twice within the last 40 hands.
SB is 28.9%SF/8.7PFR/1.6 aggro over 150 hands. We've played four hands against each other at this table. 2 were checked rivers; one of which he called down with K high and lost. The other two hands he's called my pot sized bets unable to beat top pair (my table stats: 17.8/11.7/2.2)

Overcaller is new to table 15.9/7.0/0.4 over about 80 hands.

At the time I felt that I'm looking at a decent chance of being paid of on the river given the nature of SB.. but even then I am getting odds on every street right?
