Winstar $4/$8 tough river spot with 2 pair

4 limpers, I'm on the button with T♦7♦ and I limp along, SB completes, BB checks.

I have a very narrow limpalong range on the button - I raise 66+, 87s+, Axs, K8s+, KJo+ along with all the preemies after 3 or more limpers, especially when I believe the blinds will call along with most of their range. That may be too tight, I need to rethink it and come back to this. I think this hand is just a shade too weak to try to limp along on the button hoping to "flop something" and I will probably fold this in the future.

As played:

7 players, 7 sb, flop T73r.

Checks around to the CO who bets, I raise, SB coldcalls, everyone else folds.

SB is a player I've never played with before who sat down with $300 and has literally played every single hand. He's called down to the river with some holdings that surprised even me. CO is Mr.-Check-In-The-Dark who plays too many hands and has a couple postflop leaks but isn't completely horrible. I've SEEN him bet into 5 other players with less than top pair but it doesn't happen very often.

3 players, 6bb (adjusting for rake), turn J putting out a twoflush.

Checks around to me. I have to be aware of the possibility of 98 being out there but it's a very small part of the range that BOTH of these players would take the lines they've taken with. If either of them pulled ahead of me there's a very strong chance they'd have let me know it, so a bet is basically a no-brainer. I bet, they both call. Now I'm about 99% sure I have the best hand.

3 players, 9bb, river is an A that doesn't complete a flush.

SB bets, CO raises.

Uggh. I'm getting 6 to 1 with the possibility of seeing it get reraised or even capped. CO very rarely bets the flop without at least a pair. I know nothing about SB but calling stations rarely donk into a player who's shown aggression without two pair or better. That's arguably the worst river card I could have seen (though any board-pairing card is a thread to a low, raggedy two pair like T7).

This is a horrible spot. I think this is a fold, but it's so hard to fold two pair.

Thoughts?
