I'd still be betting & probably fold to a raise as I don't see him c/r the river with a ton of hands that don't beat us/chop. If we don't bet, I think this is a big mistake as he's going to call with worse/fold.

the only hand in his range that beats you is QJhh (and he raises turn with it sometimes (and should all the time)), so I would just bet small to get a call from 2 pair/set that cant fold. You could also overbet as a bluff to fold a chop if you thought hed play a jack like this a lot (not raising turn)

If the structure of the board was different so that more flushes were possible, then I might just check behind, but it would really depend on how stationy i thought this player was.

I think this is a good bet OTR, you can still get value from 2p-sets as mentionned by toothpaste if he/she raises here you can fold

yep, vs fish and some regs i make overbet on flops like this, coz it is a good opportunity to play on stack with 2pairs+, and riverbet also standart vs fishy opponents. I realy didn't expect to see call from nitty guy, but it's NL5, and he shows TT O_O
