Check and call one bet.

You have the third best possible hand, but I don't know if you want to lead out again with two pair on the board

T9, TT, KT, KK, K9, QJs, 99, all beat you, check/call one bet,

I didn't think at all.
Took the worst line possible.

As soon as I read my post..I saw the better play..but was hitting submit already. To think, I'm usually too passive and check here...not this time.

With the exception of KT, all of these hands are very unlikely. Especially QJs, since we have the Qs.

I say **** it, and bet/call.

I think you would have heard from trip nines before the river.
I also think you would have heard from a pair of kings on the turn.

One of your opponents could be on a flush draw, but is now too scared to bet it since the board has two pair. Also, one could be such a donk that they raise with a flush draw, unaware of the possible full house, so you have to call if raised.

One of your opponents most likely has a ten. It's unlikely that one has a king because of the way the hand played out. It's also unlikely that they'll bet because of the scary nature of the board - but they probably will make crying calls.

If you get raised by an extremely passive opponent bet/fold is the best line.
