NL25-FR- jj in pos after UTG min-raise

[jk1986]

No reads on UTG min raiser, other villain has a seenflop percentage of 18.6%, and has played fairly weak tight (using pokeroffice not pokertracker so not posting aggr factor). Hero has been playing tight aggressive, with flop % of 22.6
At the table there's been a large amount of slowplaying, I've seen overpairs slowplayed on v dangerous boards. Hence the check on the flop as an attempt to keep the pot small. Would you have bet the flop?
Would you check behind on the river too?

I would have bet the flop, and if I did that I check behind on the river. As played, I think I fire at the river.
